I'm trying to make a Hi-Lo guessing game, and I've been struggling to find a way to make the game start again when the user enters '-1'.
I have just started to learn java by myself, so please let me know if you have any suggestions or advice to improve the code I made. I would really appreciate your help.
Game explanations
1)The game generates a random number between 0 and 100, and the user has to guess it. If the guess is bigger or smaller than the random number, it displays messages.
2)If the user enters a value out of range, the game displays a warning message.
3)If the guess is correct, the game gives an option asking if the user wants to play it again.
★★4)Here, when the user enters a certain value (I set it to -1), I want the game to end, but also want to give an option to start the game again.★★
//import random number generator and scanner
import java.util.Random;
import java.util.Scanner;
public class HighLowGame {
public static void main(String[] args) {
//create scanner, variables and a random number
Scanner scanner = new Scanner (System.in);
Random generator = new Random();
int number =generator.nextInt(100) + 1;
int count = 0;
boolean game = true;
//prompt user to enter a number
System.out.println("Please guess the number.(Enter -1 to quit): ");
while(game){
//user enters a number
int guess = scanner.nextInt();
//if user enters -1, the game ends
if(guess == -1){
break;
}
//guessed number is out of range
if(guess>100 || guess<0){
System.out.println("The number should be between 0 and 100.");
}
//guessed number is smaller than the random number
if(guess < number && 0 <= guess && guess <= 100 ){
count++;
System.out.println("That is too low. Please try again.(Enter -1 to quit):");
}
// guessed number is bigger than the random number
else if(guess > number && 0 <= guess && guess <= 100){
count++;
System.out.println("That is too high. Please try again.(Enter -1 to quit):");
}
//guessed number is the same as the random number
else if(guess==number) {
count++;
//displays the message and the attempt count
System.out.println("Congratulations! You got the correct number.");
System.out.println("Your attempt was " + count + " tries.");
// ask the user if they want to play the game again
count = 0;
System.out.println("Would you like to play the game again?(yes/no): ");
String another = scanner.next();
// if the user wants to end the game, it ends
if (another.equalsIgnoreCase("no")) {
break;
}
// if the user wants to play the game one more time, it starts again
else {
number = generator.nextInt(100) + 1;
System.out.println("Please guess the number(Enter -1 to quit): ");
}
}
}
}
}
