Question

java beginner level how do i add messages that say win, too high or too low for a lottery number generator guessing game?

//generate lottery numbers int lottery = (int) (Math.random() * 500);

int guess = 0; boolean correct = false;

// prompt user to enter a guess Scanner input = new Scanner(System.in);

System.out.print ("Enter your lottery pick (three digits): ");

int number = input.nextInt();

// keep asking user until user enters a 3-digit number while (guess < 100 || guess > 500) { // keep asking user until user enters a 3-digit number System.out.print("Enter your lottery pick (three digits): ");

guess = input.nextInt(); if (number == lottery) { correct = true; System.out.println("you win"); }

else if (number < lottery) { System.out.println("too low"); } else if (number > lottery) { System.out.println("too high"); }

// add error message if guess is not 3 digit number System.out.println("Error: You didnt entered a 3-digit number. Please re-enter.");

System.out.println (" the lottery number is " + lottery); } } }

Executable Code:

import java.util.Scanner;
public class Main {
   //Main Program
   public static void main(String args[]) {
       Scanner input = new Scanner(System.in);
       int guess = 0;
       boolean correct = false;
       int min = 100;
       int max=500;
       int lottery = min + (int)(Math.random() * ((max - min) + 1));
       // prompt user to enter a guess Scanner input = new Scanner(System.in);
       System.out.print ("Enter your lottery pick (three digits): ");
       guess = input.nextInt();
       // keep asking user until user enters a 3-digit number
       while (guess < 100 || guess > 500) { // keep asking user until user enters a 3-digit number
       System.out.println("Error: You didnt entered a 3-digit number. Please re-enter.(100-500");
       System.out.print("Enter your lottery pick (three digits): ");
       guess = input.nextInt();
   }
       if (guess == lottery)
       {
           correct = true;
           System.out.println("you win");
       }
       else if (guess < lottery) {
           System.out.println("too low");
       }
       else if (guess > lottery) {
           System.out.println("too high");
       }
       // add error message if guess is not 3 digit number

System.out.println ("The lottery number is " + lottery);
}
}
