JAVA Basic

Java is a widely used, versatile, and platform-independent programming language. Here are some key aspects of Java:

Introduction to Java:

Developed by Sun Microsystems (now owned by Oracle Corporation), Java was released in 1995.

It is designed to be platform-independent, meaning that Java programs can run on any device that has a Java Virtual Machine (JVM).

Write Once, Run Anywhere (WORA):

Java follows the principle of "Write Once, Run Anywhere," allowing developers to write code that can run on any device that supports Java.

Object-Oriented Programming (OOP):

Java is an object-oriented programming language, which means it is based on the concept of objects. Objects can contain data in the form of fields, often known as attributes, and code, in the form of procedures, often known as methods.

Syntax and Structure:

Java syntax is similar to C++, making it relatively easy for developers who are familiar with C-based languages to learn Java.

Java programs are organized into classes, and each class contains methods that perform specific tasks.

Platform Independence:

Java code is compiled into an intermediate form called bytecode. This bytecode is then interpreted by the Java Virtual Machine (JVM) at runtime, making it possible to run Java programs on any device with a compatible JVM.

Java Virtual Machine (JVM):

JVM is a key component of the Java Runtime Environment (JRE). It executes Java bytecode, providing the necessary runtime environment for Java applications.

Java Development Kit (JDK):

JDK is a software development kit that includes the necessary tools for Java development, such as the compiler, debugger, and other utilities.

Java Standard Edition (Java SE) and Java Enterprise Edition (Java EE):

Java SE is the standard edition of Java, suitable for developing desktop applications and standalone applications.

Java EE, now known as Jakarta EE, is an extension of Java SE with additional libraries for developing enterprise-level applications, particularly web applications.

Popular Frameworks and Libraries:

Java has a rich ecosystem of frameworks and libraries that simplify the development of various types of applications. Examples include Spring, Hibernate, and Apache Struts.

Community and Support:

Java has a large and active developer community, and there are numerous resources, forums, and documentation available for learning and troubleshooting.

Java is used in a variety of applications, ranging from mobile applications (Android development) to enterprise-level systems. It remains a popular choice for many developers due to its portability, strong community support, and versatility across different domains.

my (sarcastic) favorite part of autism is being great at high level stuff but dogshit at basic things.

im not bragging here because i was genuinely surprised by my ability, but like. in college i got A's in calculus 1 & 2 and calculus-based physics 1 & 2. i have failed math quizes in highschool just by making a bunch of arithmetic mistakes.

i cant remember which months have how many days. do NOT tell me the rhyme. i will NOT remember it. or the knuckles trick i will NOT remember it either.

How is it that i can maintain an almost 4.0 gpa but can't do this shit... thank you autism!

Most of my students (seniors in high school) don't know how to change the formatting on a word doc or in google docs. Simple stuff like "you need to change the indent and not just hit the space bar five times at the start of a new paragraph," is like fucking magic to them.

So this was originally a response to this post:

Which is about people wanting an AO3 app, but then it became large and way off topic, so here you go.

Nobody under the age of 20 knows how to use a computer or the internet. At all. They only know how to use apps. Their whole lives are in their phones or *maybe* a tablet/iPad if they're an artist. This is becoming a huge concern.

I'm a private tutor for middle- and high-school students, and since 2020 my business has been 100% virtual. Either the student's on a tablet, which comes with its own series of problems for screen-sharing and file access, or they're on mom's or dad's computer, and they have zero understanding of it.

They also don't know what the internet is, or even the absolute basics of how it works. You might not think that's an important thing to know, but stick with me.

Last week I accepted a new student. The first session is always about the tech -- I tell them this in advance, that they'll have to set up a few things, but once we're set up, we'll be good to go. They all say the same thing -- it won't be a problem because they're so "online" that they get technology easily.

I never laugh in their faces, but it's always a close thing. Because they are expecting an app. They are not expecting to be shown how little they actually know about tech.

I must say up front: this story is not an outlier. This is *every* student during their first session with me. Every single one. I go through this with each of them because most of them learn more, and more solidly, via discussion and discovery rather than direct instruction.

Once she logged in, I asked her to click on the icon for screen-sharing. I described the icon, then started with "Okay, move your mouse to the bottom right corner of the screen." She did the thing that those of us who are old enough to remember the beginnings of widespread home computers remember - picked up the mouse and moved it and then put it down. I explained she had to pull the mouse along the surface, and then click on the icon. She found this cumbersome. I asked if she was on a laptop or desktop computer. She didn't know what I meant. I asked if the computer screen was connected to the keyboard as one piece of machinery that you can open and close, or if there was a monitor - like a TV - and the keyboard was connected to another machine either by cord or by Bluetooth. Once we figured it out was a laptop, I asked her if she could use the touchpad, because it's similar (though not equivalent) to a phone screen in terms of touching clicking and dragging.

Once we got her using the touchpad, we tried screen-sharing again. We got it working, to an extent, but she was having trouble with... lots of things. I asked if she could email me a download or a photo of her homework instead, and we could both have a copy, and talk through it rather than put it on the screen, and we'd worry about learning more tech another day. She said she tried, but her email blocked her from sending anything to me.

This is because the only email address she has is for school, and she never uses email for any other purpose. I asked if her mom or dad could email it to me. They weren't home.

(Re: school email that blocks any emails not whitelisted by the school: that's great for kids as are all parental controls for young ones, but 16-year-olds really should be getting used to using an email that belongs to them, not an institution.)

I asked if the homework was on a paper handout, or in a book, or on the computer. She said it was on the computer. Great! I asked her where it was saved. She didn't know. I asked her to search for the name of the file. She said she already did that and now it was on her screen. Then, she said to me: "You can just search for it yourself - it's Chapter 5, page 11."

This is because homework is on the school's website, in her math class's homework section, which is where she searched. For her, that was "searching the internet."

Her concepts of "on my computer" "on the internet" or "on my school's website" are all the same thing. If something is displayed on the monitor, it's "on the internet" and "on my phone/tablet/computer" and "on the school's website."

She doesn't understand "upload" or "download," because she does her homework on the school's website and hits a "submit" button when she's done. I asked her how she shares photos and stuff with friends; she said she posts to Snapchat or TikTok, or she AirDrops. (She said she sometimes uses Insta, though she said Insta is more "for old people"). So in her world, there's a button for "post" or "share," and that's how you put things on "the internet".

She doesn't know how it works. None of it. And she doesn't know how to use it, either.

Also, none of them can type. Not a one. They don't want to learn how, because "everything is on my phone."

And you know, maybe that's where we're headed. Maybe one day, everything will be on "my phone" and computers as we know them will be a thing of the past. But for the time being, they're not. Students need to learn how to use computers. They need to learn how to type. No one is telling them this, because people think teenagers are "digital natives." And to an extent, they are, but the definition of that has changed radically in the last 20-30 years. Today it means "everything is on my phone."
