Important Points:

The main method in Java is no extra-terrestrial method. Apart from the fact that main() is  just like any other method & can be overloaded in a similar manner, JVM always looks for the method signature to launch the program. 


    

  • The normal main method acts as an entry point for the JVM to start the execution of program.
    • 

  • We can overload the main method in Java. But the program doesn’t execute the overloaded main method when we run your program, we need to call the overloaded main method from the actual main method only.
