Part 1 - Find on the bottom of the Jupyter Notebook linked on slide 2

Choose ONE

Write a program where the user inputs their monthly budget. The loop should then ask the user to input each of their monthly expenses. These expenses should be kept in a running total. The final output should display if the user is over or under their budget for the month, and by how much.
Write a program where a random number is generated. Then the user tries to guess the number. If they guess too high display something to let them know, and same for if they guess a number that is too low. The loop must iterate until the number is guessed correctly.

import java.util.Scanner;
import java.util.Random;

public class NumberGuessingGame {

    public static void main(String[] args) {
        int randomNumber, userNumber = 0;
        final int MAX = 100;
        char playGame = 'y';

        Random generator = new Random();

        // ask user if they wish to play
        System.out.println("Would you like to play the Number Guessing y / n");
        Scanner scan = new Scanner(System.in);

        playGame = scan.next().charAt(0);

        
		//The loop controlling the game   
		while (playGame == 'y') {
			if (playGame != 'y')
				break;

			randomNumber = generator.nextInt(MAX) + 1;
			//Creating a flag to control the inner loop
			int correct = 0;

			//The loop to control the round.
			while (correct == 0){
				System.out.println("Please pick a number between 1 and 100");
				userNumber = scan.nextInt();

				// high and low sugguestion
				if (userNumber > randomNumber)
					System.out.println("Number is too high, try something lower.\n");
				if (userNumber < randomNumber)
					System.out.println("Number is too low, try something higher.\n");
				if (userNumber == randomNumber) {
					System.out.println(randomNumber + " number is correct!");
					System.out.println("Thank you for playing!");
					correct = 1;
				}            

			}

		}

	}

}

NumberGuessingGame.main(null);
