Program in java to add two numbers?

Answer 1

import javax.swing.JOptionPane;

public class Addition

{

public static void main( String args[] )

{

String firstNumber =

JOptionPane.showInputDialog( "Enter first integer" );

String secondNumber =

JOptionPane.showInputDialog( "Enter second integer" );

int number1 = Integer.parseInt( firstNumber );

int number2 = Integer.parseInt( secondNumber );

int sum = number1 + number2;

JOptionPane.showMessageDialog( null, "The sum is " + sum,

"Sum of Two Integers", JOptionPane.PLAIN_MESSAGE );

}

}

Answer 2

#include <iostream>

using namespace std;

int main()

{

int a;

int b;

cout << "Enter A:" << endl;

cin >> a;

cout << "Enter B:" << endl;

cin >> b;

cout << "A + B =" << a+b << endl;

system("PAUSE");

return o;

}

Answer 3

a = 5;
b = 10;
c = a + b;
System.out.println("The sum is " + c);

a = 5;
b = 10;
c = a + b;
System.out.println("The sum is " + c);

a = 5;
b = 10;
c = a + b;
System.out.println("The sum is " + c);

a = 5;
b = 10;
c = a + b;
System.out.println("The sum is " + c);
