PB.MAIN

Use the method name 'main' only for the entry point method

Description

This rule checks whether the method name `main' is used for something other than the entry point method.

Because the method name `main' has a special meaning in Java, you can avoid confusion by not using it for purposes other than defining 'public static void main(java.lang.String[])'.

Example

 package PB;
 
 public class AMOP {
 
     public static void main(String[] args) {
         System.out.println("This is main method");
     }
 
     public static void main() {  //violation
         System.out.println("This is another main method");
     }
 }

Repair

 package PB;
 
 public class AMOP {
 
     public static void main(String[] args) {
         System.out.println("This is main method");
     }
 
     public static void other_main() {
         System.out.println("This is another main method");
     }
 }
