Create HelloWorld.java

We break the process of programming in Java into three steps:

    1. Create the program by typing it into a text editor and saving it to a file named, say, HelloWorld.java.
    2. Compile it by typing "javac HelloWorld.java" in the terminal window.
    3. Run (or execute) it by typing "java HelloWorld" in the terminal window.

The key line with System.out.println() send the text "Hello, World".

To print a quotation mark, a newline, or a tab, use \", \n, or \t, respectively, within the quotation marks.
