program to add two numbers in java code example

Example 1: java program to add two numbers using method

// addition program in java
import java.util.Scanner;
public class AddTwoNumbers
{
   public static void main(String[] args)
   {
      int num1, num2, sum;
      Scanner sc = new Scanner(System.in);
      System.out.println("First number : ");
      num1 = sc.nextInt();
      System.out.println("Second number : ");
      num2 = sc.nextInt();
      sum = addTwo(num1, num2);
      System.out.println("Sum : " + sum);
      sc.close();
   }
   public static int addTwo(int a, int b)
   {
      int sum = a + b;
      return sum;
   }
}

Example 2: java accept 2 integers from the user, and using a method add these numbers and print the result

static void M1(int num1, int num2) {
        int sum = num1 + num2;
        System.out.println("sum of " + num1 + " and " + num2+ " = " + sum);    
    }
 
    public static void main(String[] args) {
        // using Methods
        Scanner input = new Scanner(System.in);
        int num1,num2;
        System.out.println("Enter a number: ");
        num1 =input.nextInt();
        System.out.println("Enter 2nd number: ");
        num2 =input.nextInt();
        input.close();
        M1(num1, num2);
    }
}
