    Default Guessing Game

    public static void main(String[] args)
       {
           Scanner in = new Scanner(System.in);
           System.out.print("Enter your guess:  ");
           int input = in.nextInt();
     
           int comp = (int)(Math.random()*100) + 1;
            if(input < comp)
            {
                System.out.println("Too low");
            }
            else if(input > comp)
            {
                System.out.println("Too High");
            }
     
            else
            {
                System.out.println("Congratulations");
            }
            System.out.println("The random number was:  " + comp);
     
     
     
     
     
     
     
     
        }

    The user is supposed to keep on guessing the number if he doesn't get it correct, but my code doesn't let the person continue to guess.

    What does your program need if you want to do something over and over again?

    What you need is a loop. For example you can use a while loop like this:
    while(input!=comp){}

    You can add a do {} while loop. A do {} while loop will repeat through the code once and then again and again until the while is satisfied, for your code it would look like this:
    public static void main(String[] args)
       {
           Scanner in = new Scanner(System.in);
           int comp = (int)(Math.random()*100) + 1;
           int input = 0;
           do {
                System.out.print("Enter your guess:  ");
                input = in.nextInt();
     
                if(input < comp)
                {
                    System.out.println("Too low");
                }
                else if(input > comp)
                {
                    System.out.println("Too High");
                }
     
                 else
                {
                    System.out.println("Congratulations");
                }
                System.out.println("The random number was:  " + comp);
            } while (input != comp);
    }

    Hello loreneli113,
    The thing you need is called a cycle. More about the types of cycles you can read here.

            {
                System.out.println("Too High");
            }
     
            else
            {
                System.out.println("Congratulations");
            }
            System.out.println("The random number was:  " + comp);
     
     
     
     
     
     
     
     
        }

    How I miss the good old days when you were making a guessing game for the first time. Try using loops, like "for" and "while".

    for(ever)/while(true)/do...until(hell freezes over)

    @OP: this thread needs a break condition! Your response is that trigger that allows it to move forward.

    In fact, Junky asked a question and we are yet to hear a response. I conclude (to borrow a phrase from Peter Sellers) that this thread is either dead or... very, very good at holding its breath.
