What's Java?

Java is a programming language and computing platform first released by Sun Microsystems in 1995. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. Java is fast, secure, and reliable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!

Yes, Java is free to download. Get the latest version at java.com.

The latest Java version contains important enhancements to improve performance, stability and security of the Java applications that run on your machine. Installing this free update will ensure that your Java applications continue to run safely and efficiently.

The Java Runtime Environment (JRE) is what you get when you download Java software. The JRE consists of the Java Virtual Machine (JVM), Java platform core classes, and supporting Java platform libraries. The JRE is the runtime portion of Java software, which is all you need to run it in your Web browser.

The Java Virtual Machine is only one aspect of Java software that is involved in web interaction. The Java Virtual Machine is built right into your Java software download, and helps run Java applications.

Make It

On the empty line in the middle of the program press tab twice and type "System.out.println("Hello, World!");"

This part of any program is where we're telling the computer to do something. The heart of programming lies in being able to do this. Write this line of code and you've essentially done it. "System.out" is the first part of this instruction we need to understand. System is a class readily available at any time anywhere. Appending ".out" to System allows gives us access to a class contained in System that gives us access to the computer's output. Calling the "println" method from out will write (or print) the text passed to the method to the available output. In our case this will be the command line.

Run It!

java compilation

1. Navigate to your My Documents directory in you file explorer.

2. Create a new folder (right click hover over "New" and click on "Folder")

3. Name it "MyFirstProgramFolder" (as soon as the folder is made type out the name).

4. Drag your "MyFirstProgram" file to the folder. Do not enter the folder.

5. While holding shift right click on "MyFirstProgramFolder" and select "Open command window here...".

6. Once in the command prompt type ' " '

7. Right click in the window and select "Paste".

8. The path you copied from step 7 should appear. If not, just repeat step 7 without closing the command prompt and try again.

9. With the path pasted type ' " '

10. Type "\javac MyFirstProgram.java".

CONGRATULATIONS!! You just compiled your program. This means that your computer now has access to a file with instructions it can understand.

Better It!!

Ready to really dive into java?

Java is used amongst many frameworks (ie J2EE, Android, JavaFX etc) I would be happy to provide deeper tutorials, but these things take time. During the meantime, I reccomend you come here Click Me!

Why stop here?

We have barely scratched the surface, I am happy to take you to further into OOP (object oriented programming) or even into Game Development. As I was self taught, I want to help impart some of my Game development knowledge to you. Please stand by for the augemnted instructional pages which will allow you to learn in a more interactive environment, try hands on tools and personal user stats. Thank you for your patience!
