why it throws StackOverflowError?

   public class ClassA {
        public void count(int i)
        {
            count(++i); //throws StackOverFlowError
        }
        public static void main(String[] args) {
            ClassA a = new ClassA();
            a.count(3);
        }
    }

when I debug the code I can see that its calling count method inside the count method, but after the pre-increment is done why it keeps incrementing i variable without exiting the method?

Solution

  • You don't have a termination condition for your recursion function, The count method is being called again and again and you will get stack overflow error.
