Accepted Answer

Main() in Java refers to the entry point for any Java program and is always written as public static void main(String[] args).                                 Public: Public is an access modifier. It is used to specify who can access this method. Public means that this Method could be accessed by any Class.                                                         Static: Static is a keyword that identifies it is class-based. Main() is made static in Java so that it can be accessed without creating the instance of a class but if main is not made static then the compiler will throw an error as main() which is then called by the JVM before any objects are made and only static methods can be directly invoked via the class.                                                 Void: Void refers to the return type of the method and it defines the method which will not return any value.                                                        Main: It is the name of the method which is searched by JVM as a starting point for an application with a particular signature only and main is the method where the main execution occurs.
