Create two Exception classes: Create an Exception class called BadGuessException

Question

Create two Exception classes: Create an Exception class called BadGuessException [5 point] It will have 2 constructors A no-argument constructor that passes the message "Sorry, that was an invalid guess!" to the parent constructor using keyword super.[5 point] A parameterized constructor that will pass the parameter to the parent constructor using keyword super.[5 point] Create another Exception class called TooManyGuessesException [5 point] It will have 2 constructors A no-argument constructor that passes the message "Sorry, too many guesses!" to the parent constructor using keyword super.[5 point] A parameterized constructor that takes an integer parameter, and passes a String "Sorry, you guessed N times", to the parent constructor using keyword super. Where N is the value of the parameter. [5 point] Create a class called GuessingGame Using the Random class, generate a random number between 1 and 10. Print out the answer to the screen, to make testing the program easier. For example, you can print out "Hint: The answer is N", where N is the number that was generated [5 point] Prompt the user to guess the number. Allow the user up to 5 total attempts to guess the number correctly. [5 point] Once the user guesses the number correctly, print out "YOU WIN!" and also print out how many attempts it took the user to guess the number. [15 point] Using a single try-catch block Add exception handling to your code to throw and catch a BadGuessException if the user enters any number that is not between 1 and 10. [15 point] Add exception handling to your code to throw and catch a TooManyGuessesException if the user guesses incorrectly more than 5 times [15 point] Add another catch block to handle the exception when the user enters an incorrect format for number they guessed, such as "five" or "5.0". This should prevent your program from crashing or throwing a run time exception. When this exception is caught, the program should not crash and should display "Sorry, you entered an invalid number format". [15 point]

Explanation / Answer

GuessingGame.java

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

public class GuessingGame {

   public static void main(String[] args) {
       // Declaring variables
       int noOfGuesses = 0, randNum, userGuess, allowedAttempts = 5;

       // Scanner object is used to get the inputs entered by the user
       Scanner sc = new Scanner(System.in);

       //Creating an Random Class Object
       Random r = new Random();
      
       //generating a random number between 1 and 10
       randNum = r.nextInt(10) + 1;

       //Displaying the number
       System.out.println("Hint: The answer is " + randNum);
       System.out.print("Guess the number :");

       try {
           while (true) {
               //Checking whether the number is integer or not
               if (!sc.hasNextInt()) {
                   throw new IllegalArgumentException("Incorrect format for number");
               }
               userGuess = sc.nextInt();
               //Checking whether the number is in the range or not
               if (userGuess < 1 || userGuess > 10) {
                   throw new BadGuessException();
               } else {
                   noOfGuesses++;
               }

               //Checking whether the number of guesses exceeded
               if (noOfGuesses >= 5) {
                   throw new TooManyGuessesException(noOfGuesses);
               }

               else if (randNum == userGuess) {
                   System.out.println("YOU WIN!");
                   System.out.println("No Of attempts it took to guess :"+ noOfGuesses);
                   break;
               } else {
                   System.out.print("Guess the number :");
                   continue;
               }

           }

       } catch (Exception e) {
           System.out.println("Exception :" + e);
       }

   }
