Question

Given the ExceptionOriginal Class, run this class for Run 1plugin values 12 and 5, Run 2 plugin values 24 and 0, Run 3 plugin values 2e and view the exceptions thrown, if any.

Now modify the ExceptionOriginal class and place a test restricting user from dividing by o --- use if.... else block and display appropriate messages. Run 1 plugin values 12 and 5, Run 2 plugin values 24 and 0, and view the exceptions thrown, if any.

Now modify the ExceptionOriginal class and place a test restricting user from dividing by o (ArithmeticException class should be used to catch this exception) and other exception to be caught is (InputMismatchException)--- using try...catch block and display appropriate messages by the exception classes. Run 1 plugin values 45 and 2, Run 2 plugin values 18 and 0, Run 3 plugin values 2753 and 2f1rl.

public class ExceptionOriginal{

public static void main(String[] args) {

Scanner scan = new Scanner(System.in);

int divident, divisor, quotient;

System.out.print("Enter the divident: ");

divident = scan.nextInt();

System.out.println();

System.out.print("Enter the divisor: ");

divisor = scan.nextInt();

System.out.println();

quotient = divident/divisor;

System.out.print("Quotient = " + quotient);

}//end of main()

}//end of class

I have uploaded the Images of the code,Typed code and Output of the Code.I have provided explanation using comments(read them for better understanding).

The given class ExceptionOriginal will raise the Arithmetic Exception and InputMismatch Exceptions.

If we use the if -else block with condition divisor is non Zero value. It may overcome Exception but still may raise InputMismatch Exceptions. So we use try catch block to handle this all Exceptions

Typed Code:

//Importing required packages
import java.util.*;
public class ExceptionOriginal
{
public static void main(String[] args)
{
//creating a Scanner Object
Scanner scan = new Scanner(System.in);
//variables to store input from user
int divident, divisor, quotient;
  
//try-catch block to Handle Exceptions
//placing the entire section of code which
//may raise Exceptions in try block
try
{
//reading input divident
System.out.print("Enter the divident: ");
divident = scan.nextInt();
System.out.println();
//reading input divisor
System.out.print("Enter the divisor: ");
divisor = scan.nextInt();
System.out.println();
  
//performing division if No Exceptions raised
quotient = divident/divisor;
System.out.print("Quotient = " + quotient);
}
//using ArithmeticException class
catch(ArithmeticException e)
{
//displaying the Exception
System.out.println("\nException:"+e);
}
//using InputMismatchException class
catch(InputMismatchException e)
{
//displaying the Exception
System.out.println("\nException:"+e);
}
}//end of main()
}//end of class
//code ended here

Output:

Enter the divident: 45 Enter the divisor: 2 Quotient = 22

Enter the divident: 18 Enter the divisor: 0 Exception:java.lang.ArithmeticException: / by zero

If You Have Any Doubts. Please Ask Using Comments.

Enter the divident: 2753 Enter the divisor: 2firl Exception:java.util.InputMismatchException

Have A Great Day!
