Need help with my java project. the code is below

1. Program prompts users to play again, and resets values

2. Ask the user for both a minimum and maximum possible value for the chosen random number.

import java.io.IOException;

import java.util.ArrayList;

import java.util.InputMismatchException;

import java.util.List;

import java.util.NoSuchElementException;

import java.util.Random;

import java.util.Scanner;

public class Game {

Scanner scanner = new Scanner(System.in);

int count = userInput(scanner, "Enter number of users");

System.out.println(count);

User[] users = new User[count];

for (int indx = 0; indx < count; indx++) {

User user = new User(indx);

users[indx] = user;

}

int max = 10;

while (true) {

int allCorrect = 0;

for (int bindx = 0; bindx < count; bindx++) {

if (users[bindx].isCorrected()) {

allCorrect++;

}

}

if (allCorrect == count) {

for (int bindx = 0; bindx < count; bindx++) {

System.out.println(users[bindx].toString());

}

System.out

.println("Game finished ! Got all the correct number ");

break;

}

for (int indx = 0; indx < count; indx++) {

int randomNum = new Random().nextInt(10);

System.err

.println(" --------------------------------------------Random number "

+ randomNum);

if (!users[indx].isCorrected()) {

int userGuessValue = userInput(scanner, "Guess any number");

users[indx].getUserGuessValue().add(userGuessValue);

if (userGuessValue == randomNum) {

System.out.println("CORRECT !!");

users[indx].setCorrected(true);

} else {

System.out.println(" Oops !! Number is incorrect ");

int difference = userGuessValue - randomNum;

if (difference < 0) {

difference = -(difference);

}

if (difference >= max) {

System.err.println(" Too High !!");

} else {

System.err.println(" Too Low !!");

}

}

}

}

}

}
