Thread: Random number guessing game with three tries (loops)

What happens when you compile and execute the code?
If there are error messages, copy and paste them here.

Duplicate local variable randomNumber
randomGenerator cannot be resolved

Is the variable: randomNumber defined more than one time? Rename one of them to a different name.

PLease post the code here, not an image. Find/Search doesn't work with images.

sorry. im changing it again now i think this will be good

package assignment7;
 
import java.util.Scanner;
import java.util.Random;
 
public class Exercise1 
{
 
	static int lowNumber=0;
	static int highNumber=5;
	static int numOfGuessesAllowed=3;
 
public static void main(String[] args) 
	{
		@SuppressWarnings("resource")
		Scanner sc = new Scanner(System.in);
		Random generator = new Random();
		int target = generator.nextInt(highNumber) + lowNumber;
		int numOfGuesses=0;
		while(numOfGuesses < numOfGuessesAllowed) 
	{
 
	System.out.println("Guess a number:");
	int guess = sc.nextInt();
	boolean hasWon = checkNumber(guess, target);
	numOfGuesses++;
	if(hasWon) 
	{
		System.out.println("You win");
		System.exit(0);
	}
	}
		System.out.println("You lose");
		System.exit(0);
	}
 
public static boolean checkNumber(int guess, int target) {
	if(guess < target) 
	{
		System.out.println("Higher");
	} else if (guess > target) {
		System.out.println("Lower");
	}
	return guess==target;
	}
 
}

Compile and Run:

Guess a number:
1
Higher
Guess a number:
2
Higher
Guess a number:
3
Higher
You lose

does it compile and execute now?

Please edit your post and wrap your code with code tags:
[code=java]
YOUR CODE HERE
[/code]
to get highlighting and preserve formatting.

yes it does, and to print out the random number if the player loses would be the code below:

if(hasWon) 
	{
		System.out.println("You win");
		System.exit(0);
	}
	}
		System.out.println("You lose" + "The random number was:" + target);
		System.exit(0);
	}

and that compiles to :
Guess a number:
3
Lower
Guess a number:
3
Lower
Guess a number:
4
Lower
You loseThe random number was:2
