The public static void main function is important function in Java programming language. In this section we will learn about main function.

The main method is the first method, which the Java Virtual Machine executes. When you execute a class with the Java interpreter, the runtime system starts by calling the class's main() method. The main() method then calls all the other methods required to run your application. It can be said that the main method is the entry point in the Java program and java program can't run without this method.

The signature of main() method looks like this:

public static void main(String args[])

• public indicates that the main() method can be called by any object.
