Question

in a java application need  to create an application which prompts the user numerator and denominator values then show the result of the division.  The application will use exception handling to verify the user has entered valid input and will continue to prompt the user for input as long as the value they enter is invalid.  Once the user has entered valid numerator and denominator values, the result is shown and the application exits. had some issues when I entered letters instead of numbers . so when I enter letters in pulls up errors I need a exception handling for errors thanks

• All classes must be in a package following these rules:
  • The package name is your last name plus the first letter of your first name. For example, if you name is Rita Red, her package is “red.r”
  • Package names are all lowercase letters
• All class names must start with an UPPERCASE letter then camel-cased after that.
• All propertynames must start with a lowercase letter then came-cased after that.
• All methodnames must start with a lowercase letter then came-cased after that.
• Output must match the examples.  Watch out for spaces and punctuation.

Answer 1

import java.io.IOException;
import java.util.Scanner;

public class Division {

public static void main(String [] args) throws IOException{
int numerator;
int denominator;
  
Scanner reader = new Scanner(System.in);
System.out.println("Enter the numerator: ");
numerator = reader.nextInt();
System.out.println("Enter the denominator: ");
denominator = reader.nextInt();
try{
if(numerator <= 0 || denominator <= 0) {
throw new IllegalArgumentException("Invalid numerator / denominator value");
} else {
int result = numerator / denominator;
System.out.println("The result is: " + result);
}
}catch(Exception e){
System.out.println(e.getMessage());
}finally{
reader.close();
System.exit(0);
}
}
