Question

Write a Java Program to allow a user to guess a person’s age until they get it correct. After each guess, the user must be told whether their guess was correct, too high or too low. Once the user enters the correct age, the program must display how many guesses it took the user to guess the correct age.

Answer 1

import java.util.Scanner;

public class GuessAge {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int userAge = 21, numGuesses = 0, age;
        do {
            System.out.print("Guess my age? ");
            age = in.nextInt();
            ++numGuesses;
        } while (age != userAge);
        System.out.println("You guessed my age correctly! It took you " + numGuesses + " guesses");
    }
}
