calling main method inside main in java

Question

Can we call main method inside main?

public static void main(String[] args) {
    main({"a","b","c"});
}

Tried to google.Can't find the link. Sorry if the question is trivial

Solution 1

You can but using the correct format

main(new String[] {"a","b","c"});

should give StackOverFlowError (not tested)

Solution 2

You can. And it is very much legal.
Also, it doesn't necessarily give a StackOverFlowError:

public static void main(String args[]){

    int randomNum = (int)(Math.random()*10);

    if(randomNum >= 8)
    System.exit(0);

    System.out.print("Heyhey!");
    main(new String[]{"Anakin", "Ahsoka", "Obi-Wan"});

}

Just saying.

Solution 3

You will get StackOverFlowError. If you call endless recursive calls/deep function recursions.

Thrown when a stack overflow occurs because an application recurses too deeply.

You need to pass String array like

main(new String[] {"a","b","c"});

Solution 4

Kugathasan is right.

Yes it does give StackOverflow Exception. I tested it right now in Eclipse.

class CallingMain
{
    public static void main(String[] args)
    {
         main(new String[] {"a","b","c"});
    }
}

I have one suggestion, I think the best way to eliminate the confusion is to try coding and running it. Helps with lots of doubts.

It's StackOverFlowError

No, you cannot! Whereas the compiler won't complain, the recursion you create would exhaust the stack quite fast.

this code is not for recursion, this is simple code for calling How to call Main method

What is it when you call main from main?
