Java by Example: Hello World

Our first program will print the classic “hello world” message. Here’s the full source code.	public class HelloWorld {
	public static void main(String[] args) {
	System.out.println("Hello, World!"); } }

To run the program, put the code in `HelloWorld.java` and use `javac` to compile and `java` to run.	/ $ javac HelloWorld.java $ java HelloWorld Hello, World!
Now that we can compile and run basic Java programs, let’s learn more about the language.
