300+ TOP JAVA SWING Interview Questions and Answers

JAVA SWING Interview Questions for freshers experienced :-

1. What is Java Swing? Swing is bascially a type of Toolkit which is GUI toolkit for Java. It is one part of the Java Foundation Classes (JFC). Swing includes graphical user interface (GUI) widgets such as text boxes, buttons, split-panes, and tables. Swing widgets provide more sophisticated GUI components than the earlier Abstract Window Toolkit. Since they are written in pure Java, they run the same on all platforms, unlike the AWT which is tied to the underlying platform's windowing system. Swing supports plug gable look and feel ? not by using the native platform's facilities, but by roughly emulating them. This means you can get any supported look and feel on any platform. The disadvantage of lightweight components is slower execution. The advantage is uniform behavior on all platforms. 2. What is JFC? JFC stands for Java Foundation Classes. The Java Foundation Classes (JFC) are a set of Java class libraries provided as part of Java 2 Platform, Standard Edition (J2SE) to support building graphics user interface (GUI) and graphics functionality for client applications that will run on popular platforms such as Microsoft Windows, Linux, and Mac OSX 3. What is AWT? AWT is basically stands for Abstract Window Toolkit. AWT enables programmers to develop Java applications with GUI components, such as windows, and buttons. The Java Virtual Machine (JVM) is responsible for translating the AWT calls into the appropriate calls to the host operating system. 4. What are the differences between Swing and AWT? Many difference are there : AWT is heavy-weight components, but Swing is light-weight components. AWT is OS dependent because it uses native components, But Swing components are OS independent. We can change the look and feel in Swing which is not possible in AWT. Swing takes less memory compared to AWT. For drawing AWT uses screen rendering where Swing uses double buffering. 5. What are heavy weight components ? A Heavyweight component is basically associated with its own native screen resource which is generally known as a peer. 6. What is lightweight component? A Lightweight component is the basically one that "borrows" the screen resource of an ancestor , which means it has no native resource of its own -- so it's "lighter". 7. What is double buffering ? Double buffering is basically the process of use of two buffers rather than one to temporarily hold data being moved to and from an I/O device. Double buffering increases data transfer speed because one buffer can be filled while the other is being emptied. 8. What is an event in Swing? Event is bascially as Changing the state of an object is called an event. 9. What is an event handler in swing? An Event handler is basically a part of a computer program created to tell the program how to act in response to a specific event. 10. What is a layout manager? A layout manager is an object that is used to organize components in a container.

JAVA SWING Interview Questions 11. What is clipping? Clipping is the basically the process of confining paint operations to a limited area or shape. 12. Which containers use a border Layout as their default layout in swing? many containers are there : The window, Frame and Dialog classes use a border layout as their default layout. 13. What is the preferred size of a component? The preferred size of a component is the minimum component size, whihc will be allow the component to display normally. 14. What method is used to specify a container's layout? The setLayout() method is used to specify a container's layout. 15. Which containers use a Flow Layout as their default layout? The Panel and Applet classes use the Flow Layout as their default layout. 16. Which method of the Component class is used to set the position and size of a component? Method of the Component class is used to set the position and size of a component. hat is defined as : setBounds 17. What is the What is the difference between invokeAndWait() and invokeLater()? ? Mnay difference are there which is defined as : InvokeAndWait() method : in swing is synchronous. It blocks until Runnable task is complete. InvokeLater() method : in swing is asynchronous. It posts an action event to the event queue and returns immediately. It will not wait for the task to complete. 18. Why should any swing call back implementation execute quickly? Callbacks are invoked by the event dispatch thread. Event dispatch thread blocks processing of other events as long as call back method executes. 19. What is an applet? Applet is basically a java program that runs inside a web browser. 20. What is the difference between applications and applets? Many diff are there : Application must be run explicitly within Java Virtual Machine whereas applet loads and runs itself automatically in a java-enabled browser. Application starts execution with its main method whereas applet starts execution with its init method. Application can run with or without graphical user interface whereas applet must run within a graphical user interface. In order to run an applet we need a java enabled web browser or an applet viewer. 21. Which method is used by the applet to recognize the height and width? Method is used by the applet to recognize the height and width which is defined as : > getParameters() 22. When we should go for codebase in applet? If the applet class is not in the same directory,when we used to codebase. 23. What is the lifecycle of an applet? An Applet is basscially lifecyacle is defined as : Init( ) method : called when an applet is first loaded. Start( ) method : called each time an applet is started . Paint( ) method : called when the applet is minimized or maximized . Stop( ) method : called when the browser moves off the applet's page. Destroy( ) method : called when the browser is finished with the applet. 24. Which method is used for setting security in applets? The Method is used for setting security in applets whihc is defined as : > setSecurityManager() 25. What is an event and what are the models available for event handling? Changing the state of an object is called an event. An event is an event object that describes a state of change. In other words, event occurs when an action is generated, like pressing a key on keyboard, clicking mouse, etc. There different types of models for handling events are event-inheritance model and event-delegation model 26. What are the advantages of the event-delegation model over the event-inheritance model? Event-delegation model has two advantages over event-inheritance model. Event delegation model enables event handling by objects other than the ones that generate the events. This allows a clean separation between a component's design and its use. It performs much better in applications where many events are generated. This performance improvement is due to event-delegation model does not have to be repeatedly process unhandled events as is the case of the event-inheritance. 27. Can a class be it?s own event handler? Explain how to implement this? Sure.a Class can be its own event handler. For an example could be a class that extends Jbutton and implements ActionListener. In the actionPerformed method, put the code to perform when the button is pressed. 28. Why does JComponent have add() and remove() methods but Component does not? JComponent have add() and remove() methods but Component does not because JComponent is a subclass of Container, and can contain other components and jcomponents. 29. What is the relationship between clipping and repainting? When a window is repainted by the AWT painting thread, it sets the clipping regions to the area of the window that requires repainting. 30. What class is at the top of the AWT event hierarchy? java.awt.AWTEvent is that class which is at the top of the AWT event hierarchy. if they say java.awt.Event, they haven?t deal with swing or AWT in a while.

How to apply for Android job as a fresher in India?

Mobility and mobile technologies are literally ruling the planet like never before. Now mobile has become an indispensable tool for everyone and no more an item of luxury. More so, the job of a mobile developer has become quite enriching and enticing, commanding high respect in the software industry in terms of packages and benefits. The mobile applications we use have literally transformed how we execute our day to day tasks – be it personal or business. So, what makes this profession tick and how can one become a mobile developer or precisely an Android developer. This article talks about a few key indicators that help you to set your foot in this booming career segment.

What is so great about Android?

Android enjoys the highest market share among all the operating systems across the globe. With dominance in the mobile segment, jobs in Android offer high-level job security. And above all, the Android platform is open source, enabling the developer community to share knowledge including tips, tricks, and tutorials. In fact, developers can focus on building core apps that are in day to day use. With the booming market and myriad Android applications, this is the right time to start a career in Android development. There’s a constant flow of good jobs, wherein the demand for Android apps is soaring like never before with technology being the key driver.

Here are the few important tips that can help you land a good job in Android development:

1.     Acquire the right skill sets

Android development can be executed on any of the systems, be it Mac, Windows PC or the Linux computer. Here are some of the technologies, which you need to gain hands-on to become a right fit in Android development.

·        Java

This is the basic building block for Android development. Hence, if you need to be successful, you need to know the concepts of Java including loops, variables, lists and control structures.

·        SQL

You need to gain a basic knowledge of SQL to know how to organize the databases within the Android apps.

·        Android Software Development Kit (SDK) and Android Studio

The excellent point about Android development is that all the required tools are free of cost and easy to get. You can easily download the Android SDK for free and even the Android Studio, which is the integrated development environment (IDE) for Android app development. Of course, the best part is you can easily submit your apps to Google Play Store – simply register for a Google play publisher account, follow the checklist of Android, submit it via Google Play Developer Console, let Google approve your app and you are done.

·        XML

If you want to describe data, you need XML. Knowledge of XML syntax helps in designing user interface (UI) layouts, apart from parsing data feeds from the internet.

2.     Be a constant learner

As this is a highly competitive and rewarding field, you need to constantly hone up your skills. Good news is that you have a number of platforms including Stack Overflow, YouTube, Android Weekly and Android Developer’s site to help you learn new tips and tricks or even help you build apps. Another good source of knowledge is to read popular Android books including Head First Java and Android Programming: Pushing the Limits.

3.     Showcase your skills on popular social media sites

This is one of the popular strategies to market your skills and expertise. Showcase your Android portfolio on LinkedIn groups, Twitter chats and GitHub. This will definitely draw the attention of the prospective companies or the hiring consultants to call you for a technical meet up or even may go a one step ahead – offer you the first android programming assignment. Remember, the more you network, the more you improve the prospects of getting hired. So, always stay connected, follow the tips of the seniors and stay updated.

4.     Focus on communication skills

As for any job, having good communication skills makes a huge difference at the time of hiring. Even if you are well equipped with great technical skill sets and knowledge that can even compete with the veterans in the industry, it becomes a waste, if you are not able to project your skills properly. Hence, you need to be good at communication; both oral and written that lets you describe yourself – your personality, traits and skill sets. If you still lack confidence in expressing yourself, we recommend you to join some spoken English language courses or the best way is to start communicating with your friends, colleagues to overcome the fear of the English language. Also, develop the habit of reading good books, periodicals, and newspapers regularly to improve your vocabulary and language skills.

5.     Prepare and post a good resume in networking sites and job portals

Prepare a good resume that projects all your important skill sets and qualities that can catch the attention of the recruiter. If you are a fresher, you may not have much to showcase on the experience front and it would be practical to highlight only your school or college projects, achievements, awards or even extracurricular activities. Remember that your resume should not exceed more than 2 pages and is legible to read and understand. Also, it is preferable to post your latest photo on your resume, though not mandatory.

The next step is to post your resume in popular professional networking sites (Ex: LinkedIn) and job portals such as TapResume to help you get noticed among thousands of applicants. Unlike other job portals, TapResume is an exclusive job portal for technology jobs, focused on any IT domain or sub-domain.

6.     Apply for the right companies

Apart from posting your resume in a job portal or a networking site, you also need to be proactive to look for opportunities matching your skill sets. Shortlist the available opportunities and do a brief research about the companies, where you intend to apply. Before you actually hit the send button to email your resume, it is mandatory to prepare a good covering letter or a note. Rather than focusing more on your skill sets, your covering email should focus more on the value you would bring to the organization and how best you are suited to work in their organizations. This would create a positive impression on the minds of the recruiters before they actually look into your resume.

7.     Prepare a good question bank

Though you are yet to receive a call from prospective companies or face the actual interviews, it is better to understand the current mobility trends and prepare a good bank of probable interview questions that you might expect for the position you had applied. Take the help of the seniors in this regard and be prepared, before you actually ace the interview.

These are some of the important tips that we feel are important for you to take those first steps towards a great Android career. So, be confident, stay focused and put your heart and soul to make the best out of the opportunities to knock your door anytime.

300+ TOP ORACLE RAC Interview Questions and Answers

ORACLE RAC Interview Questions for freshers experienced :- 

1. What is cache fusion? In a RAC environment, it is the combining of data blocks, which are shipped across the interconnect from remote database caches (SGA) to the local node, in order to fulfill the reuirements for a transaction (DML, uery of Data Dictionary). 2. What is split brain? When database nodes in a cluster are unable to communicate with each other, they may continue to process and modify the data blocks independently. If the same block is modified by more than one instance, synchronization/locking of the data blocks does not take place and blocks may be overwritten by others in the cluster. This state is called split brain. 3. What is the difference between Crash recovery and Instance recovery? When an instance crashes in a single node database on startup a crash recovery takes place. In a RAC enviornment the same recovery for an instance is performed by the surviving nodes called Instance recovery. 4. What is the interconnect used for? It is a private network which is used to ship data blocks from one instance to another for cache fusion. The physical data blocks as well as data dictionary blocks are shared across this interconnect. 5. How do you determine what protocol is being used for Interconnect traffic? One of the ways is to look at the database alert log for the time period when the database was started up. Want To Get RAC Training From Experts? Enroll Now For Free Demo On Oracle RAC Training. 6. What methods are available to keep the time synchronized on all nodes in the cluster? Either the Network Time Protocol(NTP) can be configured or in 11gr2, Cluster Time Synchronization Service (CTSS) can be used. 7. What files components in RAC must reside on shared storage? Spfiles, ControlFiles, Datafiles and Redolog files should be created on shared storage. 8. Where does the Clusterware write when there is a network or Storage missed heartbeat? The network ping failure is written in $CRS_HOME/log 9. How do you find out what OCR backups are available? The ocrconfig -showbackup can be run to find out the automatic and manually run backups. 10. If your OCR is corrupted what options do have to resolve this? You can use either the logical or the physical OCR backup copy to restore the Repository.

ORACLE RAC Interview Questions 11. How do you find out what object has its blocks being shipped across the instance the most? You can use the dba_hist_seg_stats. 12. What is a VIP in RAC use for? The VIP is an alternate Virtual IP address assigned to each node in a cluster. During a node failure the VIP of the failed node moves to the surviving node and relays to the application that the node has gone down. Without VIP, the application will wait for TCP timeout and then find out that the session is no longer live due to the failure. 13. How do we know which database instances are part of a RAC cluster? You can uery the V$ACTIVE_INSTANCES view to determine the member instances of the RAC cluster. 14. What is OCLUMON used for in a cluster environment? The Cluster Health Monitor (CHM) stores operating system metrics in the CHM repository for all nodes in a RAC cluster. It stores information on CPU, memory, process, network and other OS data, This information can later be retrieved and used to troubleshoot and identify any cluster related issues. It is a default component of the 11gr2 grid install. The data is stored in the master repository and replicated to a standby repository on a different node. 15. What would be the possible performance impact in a cluster if a less powerful node (e.g. slower CPU’s) is added to the cluster? All processing will show down to the CPU speed of the slowest server. 16. What is the purpose of OLR? Oracle Local repository contains information that allows the cluster processes to be started up with the OCR being in the ASM storage ssytem. Since the ASM file system is unavailable until the Grid processes are started up a local copy of the contents of the OCR is reuired which is stored in the OLR. 17. What is the default memory allocation for ASM? In 10g the default SGA size is 1G in 11g it is set to 256M and in 12c ASM it is set back to 1G. 18. How do you backup ASM Metadata? You can use md_backup to restore the ASM diskgroup configuration in-case of ASM diskgroup storage loss. 19. What files can be stored in the ASM diskgroup? In 11g the following files can be stored in ASM diskgroups. Datafiles Redo logfiles Spfiles In 12c the files below can also new be stored in the ASM Diskgroup Password file 20. What it the ASM POWER_LIMIT? This is the parameter which controls the number of Allocation units the ASM instance will try to rebalance at any given time. In ASM versions less than 11.2.0.3 the default value is 11 however it has been changed to unlimited in later versions. 21. What is a rolling upgrade? A patch is considered a rolling if it is can be applied to the cluster binaries without having to shutting down the database in a RAC environment. All nodes in the cluster are patched in a rolling manner, one by one, with only the node which is being patched unavailable while all other instance open. 22. What are some of the RAC specific parameters? Some of the RAC parameters are: CLUSTER_DATABASE CLUSTER_DATABASE_INSTANCE INSTANCE_TYPE (RDBMS or ASM) ACTIVE_INSTANCE_COUNT UNDO_MANAGEMENT 23. What is the future of the Oracle Grid? The Grid software is becoming more and more capable of not just supporting HA for Oracle Databases but also other applications including Oracle’s applications. With 12c there are more features and functionality built-in and it is easier to deploy these pre-built solutions, available for common Oracle applications. Explore Oracle RAC Sample Resumes! Download & Edit, Get Noticed by Top Employers!Download Now! 24. What components of the Grid should I back up? The backups should include OLR, OCR and ASM Metadata. 25. Is there an easy way to verify the inventory for all remote nodes You can run the OPATCH LSINVENTORY -ALL_NODES command from a single node to look at the inventory details for all nodes in the cluster. 26. If I am using Vendor Clusterware such as Veritas, IBM, Sun or HP, do I still need Oracle Clusterware to run Oracle RAC 10g? Yes. When certified, you can use Vendor Clusterware however you must still install and use Oracle Clusterware for RAC. Best Practice is to leave Oracle Clusterware to manage RAC. For details see Metalink Note 332257.1 and for Veritas SFRAC see 397460.1. 27. Is RAC on VMWare supported? Yes. 28. What is hangcheck timer used for ? The hangcheck timer checks regularly the health of the system. If the system hangs or stop the node will be restarted automatically. There are 2 key parameters for this module: hangcheck-tick: this parameter defines the period of time between checks of system health. The default value is 60 seconds; Oracle recommends setting it to 30seconds. hangcheck-margin: this defines the maximum hang delay that should be tolerated before hangcheck-timer resets the RAC node. 29. Is the hangcheck timer still needed with Oracle RAC 10g? Yes. 30. What files can I put on Linux OCFS2? For optimal performance, you should only put the following files on Linux OCFS2: Datafiles Control Files Redo Logs Archive Logs Shared Configuration File (OCR) Voting File SPFILE 31. Is it possible to use ASM for the OCR and voting disk? No, the OCR and voting disk must be on raw or CFS (cluster file system). 32. Can I change the name of my cluster after I have created it when I am using Oracle Clusterware? No, you must properly uninstall Oracle Clusterware and then re-install. 33. What the O2CB is? The O2CB is the OCFS2 cluster stack. OCFS2 includes some services. These services must be started before using OCFS2 (mount/ format the file systems). 34. What the OCR file is used for? OCR is a file that manages the cluster and RAC configuration. 35. What the Voting Disk file is used for? The voting disk is nothing but a file that contains and manages information of all the node memberships. 36. What is the recommended method to make backups of a RAC environment?                          RMAN to make backups of the database, dd to backup your voting disk and hard copies of the OCR file. 37.  What command would you use to check the availability of the RAC system? crs_stat -t -v (-t -v are optional) 38. What is the minimum number of instances you need to have in order to create a RAC? You can create a RAC with just one server. 39.  Name two specific RAC background processes RAC processes are: LMON, LMDx, LMSn, LKCx and DIAG. 40.  Can you have many database versions in the same RAC? Yes, but Clusterware version must be greater than the greater database version. 41.  What was RAC previous name before it was called RAC?OPS: Oracle Parallel Server 42.  What RAC component is used for communication between instances?Private Interconnect. 43.  What is the difference between normal views and RAC views?A RAC view has the prefix ‘G’. For example, GV$SESSION instead of V$SESSION 44.  Which command will we use to manage (stop, start) RAC services in command-line mode? srvctl 45.  How many alert logs exist in a RAC environment? A- One for each instance. 46. What are Oracle Clusterware Components Voting Disk — Oracle RAC uses the voting disk to manage cluster membership by way of a health check and arbitrates cluster ownership among the instances in case of network failures. The voting disk must reside on shared disk. Oracle Cluster Registry (OCR) — Maintains cluster configuration information as well as configuration information about any cluster database within the cluster. The OCR must reside on shared disk that is accessible by all of the nodes in your cluster 47. How do you backup voting disk #dd if=voting_disk_name of=backup_file_name 48. How do I identify the voting disk location #crsctl query css votedisk 49. How do I identify the OCR file location check /var/opt/oracle/ocr.loc or /etc/ocr.loc ( depends upon platform) or #ocrcheck 50. What is SCAN? Single Client Access Name (SCAN) is s a new Oracle Real Application Clusters (RAC) 11g Release 2 feature that provides a single name for clients to access an Oracle Database running in a cluster. The benefit is clients using SCAN do not need to change if you add or remove nodes in the cluster. ORACLE RAC Questions and Answers pdf download Read the full article
