Project Overview

Create a number guessing game using Random, loops, conditions, and user input.

This beginner Java project helps you practice real coding skills with a small program you can run, edit, and improve.

Java Code

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

public class GuessingGame {
  public static void main(String[] args) {
    Random random = new Random();
    Scanner input = new Scanner(System.in);
    int secret = random.nextInt(10) + 1;
    int guess = 0;
    while (guess != secret) {
      System.out.print("Guess 1 to 10: ");
      guess = input.nextInt();
      if (guess < secret) System.out.println("Too low");
      else if (guess > secret) System.out.println("Too high");
    }
    System.out.println("Correct!");
    input.close();
  }
}
