Java Programming: How to Write, Compile and Run Your First Java Program

Using Windows I go through the process of how to create your very first computer program in Java. This the traditional Hello World Program.

Before following the steps in this video you must have the Java JDK downloaded and installed correctly on your computer.

Once you install that make sure you add Java to your Path environment variable as described here - https://www.java.com/en/download/help/path.xml

If you have the above steps completed then you should be able to follow what I do in the video to get the Hello World Java Program up and running.

The code used in the video is here for your convenience for copy and pasting:

public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello World");
}
}

Also here are the commands used in the command prompt:

cd Documents\Programming Tutorials
javac
javac HelloWorld.java
java HelloWorld
