Question

I need help on creating a while loop for my Java assignment. I am tasked to create a guessing game with numbers 1-10. I am stuck on creating a code where in I have to ask the user if they want to play again.

This is the code I have:

package journal3c;

import java.util.Scanner;

import java.util.Random;

public class Journal3C

{

public static void main(String[] args)

{

Scanner in = new Scanner(System.in);

Random rnd = new Random();

System.out.println("Guess a number between 1 and 10"); // Prime Loop

int count = 1;

int guess = in.nextInt();

int num = rnd.nextInt(10) + 1;

{

System.out.println("Guess a number between 1 and 10");

guess = in.nextInt();

count++;

}

if(guess == num)

System.out.println("It took " + count + " guesses to guess correctly.");

}

I just need a code on how to input : "Do you want to play again? (y/n):"

THANK YOU!

Answer 1

just put it in the do while or while loop.and their are others errors too considering the objective of the program.

code:-

package palindromes;

import java.util.Scanner;

import java.util.Random;

public class Journal3C

{

public static void main(String[] args)

{

Scanner in = new Scanner(System.in);

Random rnd = new Random();
char choice = 'y';// required if player what's to play again.

while(choice=='y')
{
System.out.println("Guess a number between 1 and 10"); // Prime Loop

int count = 1;

int guess = in.nextInt();

int num = rnd.nextInt(10) + 1;

while(guess!=num)// here,loop must exist to count the number of guesses.
{

System.out.println("Guess a number between 1 and 10");

guess = in.nextInt();

count++;

}

/*here there is no need of if(guess == num) condition because once while loop is over
guess will be definitely equal to num.*/

System.out.println("It took " + count + " guesses to guess correctly.");

System.out.print( "Do you want to play again? (y/n): ");//newly added
choice = in.next().charAt(0);/*next() is used to read string from user and charAt() is used to read character at particular
position.*/

}

}
}

output:-
