∙ 10y agoHere 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
