Two Main methods with different signatures

Question

I have following class.

public class Test {

    public static void main(Integer[] args) {
        System.out.println(\"This is not a main\"); 
    }   

           


        

Answer 1

The signature of the main method in java is public static void main(String[] args) {} and that is what the JVM's classloader loads at the start of the program. The other main with an Integer argument won't be called unless you did it manually inside main. Try modifying your code as shown below and you'll notice that nothing will be called and your program won't print anything.

public class Test {
   public static void main(Integer[] args) {
      System.out.println("This is not a real main so nothing gets printed"); 
  }   
}

Btw, you can write an overloaded main method with any argument that you want. As long as the argument is not String[] or String... which are the same, nothing will start rolling the program.
