In Java, every application begins with a class definition. In the program, HelloWorld is the name of the class, and the class definition is:

class HelloWorld {
... .. ...
}
or now, just remember that every Java application has a class definition, and the name of the class should match the filename in Java.
public static void main(String[] args) { ... }

This is the main method. Every application in Java must contain the main method. The Java compiler starts executing the code from the main method.

How does it work? Good question. However, we will not discuss it in this article. After all, it's a basic program to introduce Java programming language to a newbie. We will learn the meaning of public, static, void, and how methods work? in later chapters.

For now, just remember that the main function is the entry point of your Java application, and it's mandatory in a Java program. The signature of the main method in Java is:

public static void main(String[] args) {
... .. ...
}
System.out.println("Hello, World!");
