02. Create a class named “Calculator” having two variables “a” and “b” with a value 3 and 5 respectively.

Create an object for the class and display the results of addition, subtraction, multiplication and division operations.

For an example : 

Input : a=3 b=5

Expected output : 

Addition: 8

Subtraction: -2 or 2

Multiplication: 15

Division: 0.6

Code: 

class Calculator {
    int a = 3;
    int b = 5;

    public int addition() {
        return a + b;
    }

    public int subtraction() {
        return a - b;
    }

    public int multiplication() {
        return a * b;
    }

    public double division() {
        return (double) a / b;
    }
}

public class Main {
    public static void main(String[] args) {
        Calculator calc = new Calculator();
        System.out.println("Addition: " + calc.addition());
        System.out.println("Subtraction: " + calc.subtraction());
        System.out.println("Multiplication: " + calc.multiplication());
        System.out.println("Division: " + calc.division());
    }
}  

Output:

Copy code
Addition: 8
Subtraction: -2
Multiplication: 15
Division: 0.6  

Note: In the above code, I have defined methods addition(), subtraction(), multiplication() and division() inside the class Calculator which perform the respective operations and return the result. And then I have created an object of the class and used those methods to get the results.

👉Write a program to calculate the perimeter and the area of the rectangle. Let length and breadth be declared as an integer variable whose values are predefined. The output should be displayed in a floating format.👈
