package calculator;

public class Calculation {

      int result;

      //Method for addition

      public int add(int num1, int num2){

            result = num1+num2;

            return result;

      }

      //Method for subtraction

      public int substract(int num1, int num2){

            result = num1-num2;

            return result;

      }

      //Method for multiplication

      public int multiply(int num1, int num2){

            result = num1*num2;

            return result;

      }

      //Method for division

      public float divide(int num1, int num2){

            result = num1/num2;

            return result;

      }

      private int firstNumber;

      private int secondNumber;

     

      public int getFirstNumber() {

            return firstNumber;

      }

      public void setFirstNumber(int firstNumber) {

            this.firstNumber = firstNumber;

      }

      public int getSecondNumber() {

            return secondNumber;

      }

      public void setSecondNumber(int secondNumber) {

            this.secondNumber = secondNumber;

      }

     

}

Source: MainClass.java

package calculator;

public class MainClass {

      public static void main(String[] args) {

           

            CalculatorVO calVO = new CalculatorVO();

            //Input can be taken from user

            calVO.setFirstNumber(100);

            calVO.setSecondNumber(11);

           

            Calculation cal = new Calculation();

           

            int addResult = cal.add(calVO.getFirstNumber(), calVO.getSecondNumber());

            System.out.println("Addition Result ="+addResult);

           

            int subResult = cal.substract(calVO.getFirstNumber(), calVO.getSecondNumber());

            System.out.println("Subtraction Result ="+subResult);

           

            int mulResult = cal.multiply(calVO.getFirstNumber(), calVO.getSecondNumber());

            System.out.println("Multiplication Result ="+mulResult);

           

            float divResult = cal.divide(calVO.getFirstNumber(), calVO.getSecondNumber());

            System.out.println("Division Result ="+divResult);

      }

}

OUTPUT:

Addition Result =111

Subtraction Result =89

Multiplication Result =1100

Division Result =9.0
