The standard "Hello World" program in Java looks like:

class HelloWorld {

public void main(String[] args)

{

System.out.println("Hello World");

}

} //end class

Here is a program which I copied from the Wikipedia article on the Java programming language:

class HelloWorldApp {

public static void main(String[] args) {

System.out.println("Hello World!"); // Display the string.

}

}

Note that in some Java IDEs, if you create a new Java class, the outer "skeleton", which is standard for many classes, is provided automatically; in this case, all you have to complete is the line that starts with System.out.println.

You can experiment with this, and print other texts; or do calculations; you can also add several System.out.println() lines, for example:

System.out.println("Yes, I am starting to learn Java");

System.out.println("1 + 2"); // Result is "1 + 2"

System.out.println(1 + 2); // Result is 3

System.out.println(1 + 2 * 3); // Result is 7
