// HelloWorld.java // This program (your first Java program!) demonstrates some basics // of Java programming. What you are now reading is a COMMENT. It is // not part of the program, per se -- you can place anything you like // in a comment, and Java will ignore it. You use comments to communicate // with other people, not with Java. You create a comment by typing // two consecutive slashes on a line -- everything after that is a comment. class HelloWorld { public static void main(String[] args) { System.out.println("Hello World!"); } }
