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

Because Strings are what you're passing into the command line.

the 45 from

myProgram.exe 45

is not an integer. it is a string containing the characters 4 and 5

It just so happens that you can use a string like "45" to represent an integer. It's a little more difficult to do it the other way around.(for the user at least)
