How to do Addition in Java

Step 1: Declare two numbers (variables)

int num1 = 5;
int num2 = 10;


Step 2: Add the two numbers and store the result

int sum = num1 + num2;


Step 3: Print the result

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

Full example program:

public class AdditionExample

{


public static void main(String[] args)

 {

   int num1 = 5;
