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. Themain() 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[])
The method signature for the main() method contains three modifiers:
- public indicates that the main() method can be called by any object.
- static indicates that the main() method is a class method.
- void indicates that the main() method has no return value.
