Question

Write a Java program to add two numbers and display the result in the output screen.​

Answer 1

Explanation:

Program to Add Two Integers

public class AddTwoIntegers {

public static void main(String[] args) {

int first = 10;

int second = 20;

System.out.println("Enter two numbers: " + first + " " + second);

int sum = first + second;

System.out.println("The sum is: " + sum);

}

}

Output:

Enter two numbers: 10 20

The sum is: 30

In this program, two integers 10 and 20 are stored in integer variables first and second respectively.

Then, first and second are added using the + operator, and its result is stored in another variable sum.

Finally, sum is printed on the screen using println() function

Answer 2

Answer:

import java.util.Scanner;

public class add

{

public static void main(String[] args)

{

Scanner sc=new Scanner(System.in);

System.out.print("ENTER THE FIRST NUMBER")

double a=sc.nextInt();

System.out.print("ENTER THE SECOND NUMBER")

double b=sc.nextInt();

double c=a+b;

System.out.println("THE SUM OF  "+a+" and "+b+" is "+c)

 }

}
