Title: Create a Java Program to Add Two Numbers Using a User-Defined Method
Problem
Write a Java program that demonstrates the use of methods. Create a method named addNumbers() that accepts two integer values as parameters, calculates their sum, and returns the result. In the main() method, create an object of the class, call the method, and display the sum. 
Solution 
public class Calculator {
    public int calulateSum(int firstNumber, int secondNumber) {
        return firstNumber + secondNumber;
    }
    public static void main(String[] args) {
        int num1 = 25;
        int num2 = 28;
        Calculator calculator = new Calculator();
        int result = calculator.calulateSum(num1, num2);
        System.out.println("Sum of numbers is: " + result);
    }
}
