Java Concurrency: Managing Threads and Synchronization

Is there anything more fascinating than how the applications you use for your everyday tasks can provide you with multiple tasks at once, seamlessly juggling between different actions? Java concurrency holds the answer.

Concurrency refers to the ability of a system or program to execute multiple tasks concurrently. In the context of Java programming, it involves managing threads and synchronization to ensure the efficient execution of concurrent tasks.

Concurrency in Java brings about its own set of challenges. Coordinating access to shared resources among threads can lead to issues like race conditions, deadlocks, and inconsistent data states. To tackle these challenges, developers need to understand how to manage threads and synchronize their actions effectively.

This article provide a comprehensive understanding of concurrent programming in Java. We will explore topics such as thread creation and management techniques, as well as synchronization mechanisms like locks, semaphores, monitors, etc. 

Let's take a look at Java's threads and synchronization.

Understanding Threads in Java

Threads are a fundamental concept in Java that allows for concurrent execution of multiple tasks within a program. A thread can be considered an independent flow of control that operates within the context of a process. By utilizing threads, developers can achieve parallelism and improve the performance and responsiveness of their applications.

In Java, threads go through different states during their lifecycle:

New: When a thread is created but has not yet started.

Runnable: The thread is ready for execution and waiting for available CPU time.

Blocked: A blocked thread is temporarily paused due to synchronization or resource constraints.

Waiting: A thread enters the waiting state when it waits indefinitely until another notifies it.

Terminated: The final state of a terminated thread after it completes its execution or terminates prematurely.

In Java, there are two ways to create it:

By extending the Thread class: This approach involves creating a subclass of Thread and overriding its run() method.

By implementing the Runnable interface: This approach separates the code responsible for running tasks from the threading logic.

Each Java thread has an associated priority ranging from 1 (lowest) to 10 (highest). These priorities help determine how much CPU time each thread receives relative to others with different priorities. However, relying solely on priorities for precise control over scheduling is not recommended since it depends on platform-specific implementations.

Here is a list of the best Java development companies: Intelliware Development, Jelvix, Cleveroad, The Brihaspati Infotech, DevCom, BrainMobi, Zibtek, and Itransition. Each of these companies has extensive experience developing Java applications and is well-equipped to provide top-quality services.

Thread Synchronization

In concurrent programming, thread synchronization is essential to ensure the correct and predictable execution of multiple threads accessing shared resources. Without proper synchronization, race conditions and data inconsistencies can occur, leading to unexpected behavior.

Java provides synchronized blocks and methods as mechanisms for thread synchronization. By using the synchronized keyword, you can restrict access to critical sections of code, allowing only one thread at a time to execute them. This ensures that shared resources are accessed in a controlled manner.

In addition to synchronized blocks and methods, Java offers more explicit control over thread synchronization through locks. The ReentrantLock class provides advanced features such as fairness policies and condition variables that enable fine-grained control over locking mechanisms.

To achieve thread safety, it is crucial to design classes in a way that allows safe concurrent access by multiple threads without introducing race conditions or data corruption. One approach is creating immutable objects - objects whose state cannot be modified once created. Immutable objects eliminate the need for synchronization since they can be safely shared among threads without any risk of interference.

Java Concurrent Collections

Java provides a set of concurrent collections designed to be thread-safe and support efficient concurrent access. These collections ensure that multiple threads can safely access and modify the stored data without encountering issues like data corruption or race conditions.

ConcurrentHashMap is a high-performance concurrent implementation of the Map interface. It allows multiple threads to read from and write to the map concurrently, providing better scalability compared to traditional synchronized maps. It achieves this by dividing the underlying data structure into segments, allowing different threads to operate on different segments simultaneously.

The ConcurrentLinkedQueue class implements a thread-safe queue based on linked nodes. It supports concurrent insertion, removal, and retrieval operations without explicit synchronization. This makes it suitable for scenarios where multiple threads need to access a shared queue efficiently.

When iterating over a collection while other threads modify it concurrently, a ConcurrentModificationException is possible. To overcome this issue, Java provides fail-safe iterators in concurrent collections. Fail-safe iterators create copies of the original collection at the time of iteration, ensuring that modifications made during iteration do not affect its integrity.

Executor Framework

The Executor framework provides a higher-level abstraction for managing and executing tasks asynchronously. It simplifies the process of thread creation, management, and scheduling, allowing developers to focus on the logic of their tasks rather than dealing with low-level threading details.

ThreadPoolExecutor` is an implementation of the `ExecutorService` interface that manages a pool of worker threads. It allows efficient reuse of threads by maintaining a pool instead of creating new ones for each task. The ThreadPoolExecutor dynamically adjusts the number of threads based on workload and can handle large numbers of concurrent tasks efficiently.

The `Executors` class provides factory methods to create different types of executor services, such as fixed-size thread pools, cached thread pools, or scheduled thread pools. These pre-configured executor services simplify the setup process by providing convenient defaults for common use cases.

The `ExecutorService` interface represents an asynchronous execution service that extends the base `Executor`. It adds additional functionality like managing task submission, tracking progress using futures, and controlling termination.

The `Future` interface represents a result of an asynchronous computation. It provides methods to check if the computation has been completed, retrieve its result (blocking if necessary), or cancel it if desired.

The `Callable` interface is similar to a `Runnable`, but it can return a value upon completion. Callables are submitted to executor services using methods like `submit()` or `invokeAll()`, which return corresponding Future objects representing pending results.

Java Memory Model

The Java Memory Model (JMM) defines the rules and guarantees for how threads interact with memory in a multi-threaded environment. It specifies how changes made by one thread become visible to other threads.

The volatile keyword is used in Java to ensure that variables are read and written directly from/to the main memory, bypassing any local caching mechanisms. It guarantees visibility across multiple threads, ensuring that changes made by one thread are immediately visible to others.

The happens-before relationship is a key concept in JMM. It establishes order between actions performed by different threads. If an action A happens before another action B, then all changes made by A will be visible to B when it executes.

Memory consistency errors occur when multiple threads access shared data without proper synchronization, leading to unpredictable behavior or incorrect results. To avoid such errors, developers can use synchronization mechanisms like locks or synchronized blocks/methods to establish proper ordering of operations on shared data.

Additionally, using atomic classes from the java.util.concurrent package or concurrent collections ensures atomicity and thread safety without explicit locking.

Thread Communication

Interthread communication refers to the mechanisms used by threads to coordinate and exchange information with each other. It allows threads to synchronize their actions, share data, and work together towards a common goal.

The Object class provides methods like wait(), notify(), and notifyAll() for inter-thread communication. These methods are used in conjunction with synchronized blocks or methods to enable threads to wait for certain conditions and signal when those conditions are met.

The producer-consumer problem is a classic synchronization problem where one or more producer threads generate data items, while one or more consumer threads consume these items concurrently. 

Proper thread communication techniques, such as using shared queues or buffers, can be employed to ensure that producers only produce when there is space available in the buffer, and consumers only consume when there are items present.

Java's BlockingQueue interface provides an implementation of a thread-safe queue that supports blocking operations such as put() (to add elements) and take() (to retrieve elements). Blocking queues facilitate efficient thread communication by allowing producers to block if the queue is full and consumers to block if it is empty.

Best Practices for Concurrency in Java

To avoid deadlocks, it is crucial to ensure that threads acquire locks in a consistent order and release them appropriately. Careful analysis of the locking hierarchy can prevent potential deadlocks. Additionally, using thread-safe data structures and synchronization mechanisms helps mitigate race conditions.

Minimizing shared mutable state reduces the complexity of concurrent programming. Immutable objects or thread-local variables eliminate the need for explicit synchronization altogether. When sharing mutable state is unavoidable, proper synchronization techniques like synchronized blocks or higher-level abstractions should be employed.

Thread pools provide efficient management of worker threads by reusing them instead of creating new ones for each task. However, it's important to choose an appropriate pool size based on available resources to avoid resource exhaustion or excessive context switching.

Properly shutting down threads is crucial to prevent resource leaks and ensure application stability. Using ExecutorService's shutdown() method allows pending tasks to complete while rejecting new tasks from being submitted. It's also important to handle interruptions correctly and gracefully terminate any long-running operations.

Conclusion

Understanding Java concurrency concepts and proper thread management is crucial for building successful and efficient applications. By leveraging the power of concurrency, developers can enhance application responsiveness and utilize system resources effectively. Properly managing threads ensures that tasks are executed concurrently without conflicts or resource contention.

Successful offshore development management also relies on a solid grasp of Java concurrency. Efficient use of concurrent programming allows distributed teams to collaborate seamlessly, maximizing productivity and minimizing communication overhead.

Incorporating concurrency in Java development enhances performance and scalability, a key to offshore success. Finoit, led by CEO Yogesh Choudhary, champions this approach for robust software solutions.

[lionmageaz]

Some notes on my efforts to implement the Gamma function 𝚪(z).

[ladyhindsight]

There’s some rewriting past actions and relationships and a lot more world-building but the kind that creates more questions. This chapter also contains many statements and observations that make no sense due to lack of previous context in the series (or outright lies), so I’m just really fighting my way through. And it’s only the first proper chapter.

The chapter begins with Jordan giving Jace Jedi training.

An independent eye → Jace cracked his eye open.

God forbid they actually want to spend time together as well and support Jace.

Jordan and Jace have very different views on things that are relaxing and so the meditating session isn’t going well. Then Simon and Clary appear.

Fact check time. Clary and Simon go to Java Jones in City of Bones chapter 3 “Shadowhunter.” Simon immediately goes to get them coffee and Clary goes to find them a seat. A random blonde girl asks Clary whether Simon was her boyfriend, had a girlfriend, or was gay. Clary doesn’t get to respond as Simon returns with their coffees and:

Clary tried to hide a smile as she watched him. Normally she never thought about whether Simon was good-looking or not. He had pretty dark eyes, she supposed, and he’d filled out well over the past year or so.

Clary has an inner battle whether to tell Simon about the girl being interested in him, but decides to tell him and they talk about girls. Clary is resentful and Simon is gloomy and then agitated and then looks faintly greenish. Neither of them seemingly are having particularly fun time nor are laughing like the scene here seems to imply. Then Jace appears and Clary leaves Java Jones going after him. After that the phone call happens and Clary leaves with Jace to check on Jocelyn.

→ There is strange insistency on rewriting history when the scene in Java Jones was nothing like this. They were barely even there before Clary left. The only thing true here is Clary leaving Simon behind and following Jace out to talk to him.

Aside from totally loving the subtext being once again spelled out

→ tense change, new thought, so new paragraph

→ Clary has yet to convince me

Period.

Participle phrases indicate concurrency. Jordan be gone, as in no longer present, while still being in the middle of leaving (in line of sight).

→ He gave a mock salute and slipped into the trees, vanishing with the silent tread…

Blood doesn’t have a pulse. Either “his veins pulsating” or just “pulse”

That’s anything this series as a whole has. Besides, what do you expect, kissing out in the open and right in front of them? (It’s a joke, I know)

→ Would’ve loved this energy in the other books as well, not just in the final one. That makes this rather disingenuous.

→ How would Alec know when Jace has a strange way of showing it (meaning not at all)?

By all accounts there is so much reliable narrative and evidence of Sebastian being a threat. They, whoever they even are, don’t want to believe it because it’s convenient for the plot. Again.

The transition from this to Jace (and Clary) being well-loved by the Clave is weird because there no proper bridge between the two points. Also interested in seeing where this book takes Clary’s trauma, because I don’t remember a lot.

Go away, Clary. This also doesn’t really explain why the bodies could not be examined nonetheless. Old remains can still be examined.

In the Codex it is said that it is often believed that when a Shadowhunter names a seraph blade, the blade not only becomes engulfed by heavenly fire, but some of the named angel's spirit is infused into the blade as well. So is it not believed or is it not just true? Where would the belief and thus the heavenly fire come from if they never managed to capture it in a weapon?

→ Why are two former Shadowhunters celebrating Thanksgiving while it seems to escape a Shadowhunter that is oblivious of such mundane celebrations? For the joke? Okay.

→ Why would the Shadowhunters be annoyed at being left out? Since here they evidently have their own celebrations as well. Why would they care about mundane holidays based on mundane religions they do not even adhere to because ALL THE STORIES ARE TRUE? The idea of being “left out” is stupid because they do not celebrate it with mundane world anyway. Additionally it seems the Shadowhunters celebrate Christmas in a very modern sense (a cultural celebration) because their celebration has nothing to do with Christ, and Clare actively seems to avoid the original meaning of Christmas (being central to Christianity).

→ How thoughtful of you to remember that.

The Lightwood-Herondales have to return to the Institute for a shindig, and Simon and Clary go for Christmas/Hanukkah shopping.

Why would they be though? They are Shadowhunters, but they can appreciate the atmosphere of Christmastime still.

→ Can’t believe we are still in this point after the whole debacle in City of Fallen Angels.

→ We have encapsulated Isabelle’s essence to perfumes (and Magnus to body glitter). Calls nicely back to City of Bones, but per Clary’s judgement then, Isabelle wants to smell like desserts. (love the transition from contempt to support though)

Since we have touched upon the subject here, I still hate the thought never goes deeper than that. So I’ll direct here.

Can’t trust the Clave to handle anything but can trust the Clave not to drop the ball with Simon. Right.

Worried Jocelyn appears out of nowhere and tells Clary they have to go to the Institute at once.

Just for the sake of having pointed one these (of the many) out → A Cold washed through her veins.

We cut to Jace visiting Magnus.

Once again, I’ll direct here. Love that no matter what, Jace has Alec’s back despite Alec being in the wrong (in principle, but what I think is elaborated in that other post.)  Also the idea that it would be a happy relationship if their friends managed to convince Magnus is just nonsense.

→ What a dumb fucking question (in the seemingly obvious context of Jace being Alec’s parabatai, not that his actions in the past generally ever indicate this being the case)

→ You could’ve fit ‘my brother’ in there somewhere

→ You don’t really care about yourself so the bar is not that high

Jace gets a call from Isabelle. She tells him to return to the Institute immediately because they have learned that Sebastian has happened. Jace leaves Magnus with an epic burn and we cut to the Institute, where Sebastian’s actions are revelead.

→ Why aren’t they fully informed?

→ Why did they not react after the first? Why wait for this meeting after two?

→ Why the breaches are such a mystery? Sebastian, no matter what, is still Nephilim. What stops him from entering any Institute at will anyway?

→ What intelligence and where? How did they come to this conclusion?

→ Why didn't they take into account the safety of the Institutes as well? It’s ridiculous that none of the Clave have brains.

The Clave has called for immediate evacuation for all the Institutes. Yay, we’re going back to Idris.

Languages like Haskell, Lisp, Erlang, and some features in languages like JavaScript, Python, and Scala support functional programming paradigms.

Reactive Programming Reactive Programming deals with asynchronous data streams and the propagation of changes. Event-driven applications, and streaming data processing applications benefit from reactive programming.

Generic Programming Generic Programming aims at creating reusable, flexible, and type-independent code by allowing algorithms and data structures to be written without specifying the types they will operate on. Generic programming is extensively used in libraries and frameworks to create data structures like lists, stacks, queues, and algorithms like sorting, searching.

Concurrent Programming Concurrent Programming deals with the execution of multiple tasks or processes simultaneously, improving performance and resource utilization. Concurrent programming is utilized in various applications, including multi-threaded servers, parallel processing, concurrent web servers, and high-performance computing.

[orbitwebtech]

NodeJS excels in web development with its event-driven, non-blocking I/O model, making it ideal for handling concurrent connections and real-time applications like chat apps and live streaming. Its single-threaded architecture and use of JavaScript, both on the server and client side, allow for seamless development across the entire stack. NodeJS is especially suitable for startups and projects that require fast, scalable, and high-performance solutions.

Java, on the other hand, is renowned for its robustness, security, and platform independence. It is a mature technology with a vast ecosystem and a wealth of libraries and frameworks, such as Spring and Hibernate, which facilitate the development of large-scale, enterprise-grade applications. Java's multithreading capabilities and strong memory management make it well-suited for complex, resource-intensive applications where stability and reliability are paramount.

Choosing between NodeJS and Java ultimately depends on the specific needs of your project. For real-time, scalable applications with a need for rapid development, NodeJS is a compelling choice. For enterprise-level applications requiring high stability, security, and comprehensive tool support, Java is often the preferred technology.

Version 1.3.2 of Cornbread's Music Fixer!! I know I literally just merged the Bedrock and Java Edition releases of the pack, but I've decided it would actually be less confusing if they were separate, so I separated them. For those keeping track at home, that means there are now four concurrent versions of the pack!

Apart from editions being split again, 1.3.2 is a minor update that only changes, like, two things. Sorry this is coming out so close to Tricky Trials and has nothing to do with Tricky Trials. I meant to get this out sooner.

Links:

Bedrock Style for Bedrock Edition

Bedrock Style for Java Edition

Java Style for Bedrock Edition

Java Style for Java Edition

Changelog:

Bedrock Style (both editions):

Lowered the volume of Ancestry from 100% (vanilla) to 20%.

Bedrock Edition (both styles):

Added a short description of each subpack under its name.

Removed text "Choose where 'A Familiar Room' will play." from subpack selection as it is now redundant.

Added subpack "Survival Mode+". This subpack makes A Familiar Room and various tracks from the Caves and Cliffs Update play in the Overworld when not in Creative Mode, essentially reverting the selection of non-biome-specific music to how it is in vanilla Java Edition.

Added subpack "Old Growth Taiga+". This subpack makes A Familiar Room and various tracks from the Caves and Cliffs Update play in Old Growth Taigas, essentially reverting their music selection to vanilla, but replacing the swamp music with A Familiar Room.

Subpack "Menu Only" now properly prevents A Familiar Room from playing outside the menu.

A Familiar Room now plays at the correct weight in sound event "music.game_and_wild_favor_game" with subpack "Survival Mode" enabled.

Java Edition (both styles)

The Arboretum in snapshot 24w14potato now plays the correct music. Unfortunately, this means that Flower Forests also play this music in snapshots 24w12a and 24w14potato, due to limitations in Java Edition.

Java Style for Java Edition:

Removed JSON for music.overworld.desert and music.overworld.badlands since they were functionally identical to vanilla.
