Avoid printing the last comma

Question

I\'m trying to print this loop without the last comma. I\'ve been Googling about this and from what i\'ve seen everything seems overcomplex for such a small problem. Surely

Answer 1

You can simply use escape sequence for backspace(\b),outside the main loop,it will delete the last comma.

public static void atob(int a,int b)
        {
            for(int i = a; i <= + b; i++) 
            {
                    System.out.print(i + ",");
            }
            System.out.print("\b");
        }
