Question

Chapter 11 Assignment (Exception Handling) - 10 points Your goal is to rewrite a past program to include exception handling. Rewrite one of the following exercises to include exception handling: o Guessing Game o Tallying Coin Toss The exception handling should handle bad input. (4 points) It should re-prompt the user for the correct input until the user enters valid input. (6 points) .

This is the source code: Please incorporate the Exception Handling

import javax.swing.JOptionPane;
import java.awt.*;

public class GuessingGame {
public static void main(String[] args) {

int computerNumber = (int) (Math.random() * 10 + 1);

System.out.println("The correct guess would be " + computerNumber);
int userAnswer = 0;
int count = 0;

while (computerNumber != userAnswer) {
count++;

String response = JOptionPane.showInputDialog(null,
"Enter a guess between 1 and 10");

userAnswer = Integer.parseInt(response);
String result = null;

if (userAnswer == computerNumber) {
result = "Correct";
} else {
if (userAnswer <= 0 || userAnswer > 10) {
result = "Invalid guess";
} else if (userAnswer > computerNumber) {
result = "Too High";
} else {
result = "Too Low;";
}
}
JOptionPane.showMessageDialog(null, result +
"\nTry Number " + count);
}
if (count == 1){
JOptionPane.showMessageDialog(null,"You must be psychic!");
} else if (count < 3){
JOptionPane.showMessageDialog(null, "Amazing");
} else if (count < 5){
JOptionPane.showMessageDialog(null,"Great Job");
} else {
JOptionPane.showMessageDialog(null, "You need some practice");
}
}

}

Program

import java.util.InputMismatchException;

import javax.swing.JOptionPane;

public class GuessingGame {
   public static void main(String[] args) {
       //Generate random number
       int computerNumber = (int) (Math.random() * 10 + 1);
        System.out.println("The correct guess would be " + computerNumber);
        int userAnswer = 0;
        int count = 0;
        //Loop until guess will be correct
        while (computerNumber != userAnswer) {
           //Guess count
           count++;
           try {
               //Prompt for user guess
               String response = JOptionPane.showInputDialog(null,"Enter a guess between 1 and 10");
               //Read user guess
               userAnswer = Integer.parseInt(response);
               String result = null;
               if (userAnswer == computerNumber) {
                   result = "Correct";
               }
               else {
                   //Exception out of range
                   if (userAnswer <= 0 || userAnswer > 10) {
                       //result = "Invalid guess";
                       throw new InputMismatchException("Invalid guess!Must be 1-10!!");
                   }
                   else if (userAnswer > computerNumber) {
                       result = "Too High";
                   }
                   else {
                       result = "Too Low;";
                   }
                }
               JOptionPane.showMessageDialog(null, result +"\nTry Number " + count);
               }catch(NumberFormatException ex) { //Exception when input is not integer
                   JOptionPane.showMessageDialog(null,"Invalid input||must be integer!!!other than "+ex);
               } catch (InputMismatchException ex) { //Out of range excepion generator
                   JOptionPane.showMessageDialog(null,ex);
                }
        }
           //Display revies result according to attempt count
           if (count == 1){
               JOptionPane.showMessageDialog(null,"You must be psychic!");
           }
           else if (count < 3){
               JOptionPane.showMessageDialog(null, "Amazing");
           }
           else if (count < 5){
               JOptionPane.showMessageDialog(null,"Great Job");
           }
           else {
               JOptionPane.showMessageDialog(null, "You need some practice");
           }
        }
   }

Note

Please add your second program for adding exception handling.

Here i add input mismatch and out of range exceptions
