How to restart a method from inside it in java

Question

Hi, is there a way of restarting a method in java from inside the one you want rerun?

thanks

Answer 1

recursion? of course java supports it

public int foo (int param) {
   if (param == 0)
       return 0;
   return param + foo (--param);
}

public static void main (String[] args) {
   System.out.println (foo (5));
}

Answer 2

I guess you want to use recursion.

Answer 3

Not sure what you are trying to do, but you can simply call a method from itself (it's called recursion):

void recursiveMethod() {
    System.out.println("Called the recursive method");
    recursiveMethod();
}

Calling that method will print the line "Called the recursive method" until you get a StackOverflowError.

Answer 4

You can call the method again from inside itself (AKA recursion). So, something like this:

public void myMethod() {
  // Do some stuff here.

  // Possible conditional statement...
  if(restart) {
    myMethod();  // This will "restart" the method.
  }
}

If you have a more specific example that you're thinking of, that may help improve your question.
