Question

Create method addUserInput

Write a method called addUserInput().

The method should ask the user to input two integers (one by one), add the two integers, and return the sum.

By using java.util.Scanner to get user input;

The method may not compile due to Scanner Class which need to add a "throws" statement onto the end of the method header because some lines may throw exceptions

Refer to the Java API documentation on Scanner to figure out which specific Exception should be thrown from your method - do not add “throws Exception”.

I only want the addUserInput() method to write out in code with a specific Exception it needs in the method. In Java, it would be appreciated thanks.

Code is Given Below:

========================

import java.util.InputMismatchException;
import java.util.Scanner;

public class UserInputDemo {
   //main method
   public static void main(String[] args) throws InputMismatchException {
       UserInputDemo ui=new UserInputDemo();
       //calling method to find sum
       int sum=ui.addUserInput();
       System.out.println("Sum is : "+sum);
      
   }
  

  
   //creating method
   public int addUserInput() throws InputMismatchException{
       //creating scanner object to get user input
       Scanner scn=new Scanner(System.in);
       //asking user for input
       System.out.print("Enter first Number : ");
       int num1=scn.nextInt();
       System.out.print("Enter second Number : ");
       int num2=scn.nextInt();
       //finding sum and returning it
       return num1+num2;
   }

}

Output:
