Question

Create a class called RandomGuess. In this game, generate and store a random number between 1 and 100. Then, continuously (in a loop):

• Ask the user to enter a number between 1 and 100
• Let the user know if the guess is high or low, until the user enters the correct value
• If the user enters the correct value, then display a count of the number of attempts it
  took and exit

import java.util.Random;
import java.util.Scanner;

public class RandomGuess {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        Random random = new Random();
        int number = random.nextInt(100) + 1;
        int tries = 0, guess;
        while (true) {
            System.out.print("Guess number: ");
            guess = in.nextInt();
            tries++;
            if (guess == number) {
                break;
            }
            if (guess < number) {
                System.out.println("That is too low – Guess again");
            } else {
                System.out.println("That is too high – Guess again");
            }
        }
        System.out.println("Congrats! It took you " + tries + " tries!");
    }
}
