Question

Write a java program to take two numbers from user and find the sum using function Add( ).​

Answer 1

Answer:

First Example: Sum of two numbers

public class AddTwoNumbers {

public static void main(String[] args) {

int num1 = 5, num2 = 15, sum;

sum = num1 + num2;

System.out.println("Sum of these numbers: "+sum);

}

}

Output:

Sum of these numbers: 20

Second Example: Sum of two numbers using Scanner

The scanner allows us to capture the user input so that we can get the values of both the numbers from user. The program then calculates the sum and displays it.

import java.util.Scanner;

public class AddTwoNumbers2 {

public static void main(String[] args) {

int num1, num2, sum;

Scanner sc = new Scanner(System.in);

System.out.println("Enter First Number: ");

num1 = sc.nextInt();

System.out.println("Enter Second Number: ");

num2 = sc.nextInt();

sc.close();

sum = num1 + num2;

System.out.println("Sum of these numbers: "+sum);

}

}

Output:

Enter First Number:

121

Enter Second Number:

19

Sum of these numbers: 140

Answer 2

Answer:

import java.util.Sacnner;

public class addtion

{

      public void add()

    {

            Scanner sc=new Scanner(System.in);

               System.out.println("Enter two numbers.");

            int num1=sc.nextInt();

               int num2=sc.nextInt();

               int sum=num1+num2;

                return sum;

}

               

    }
