In this exercise, you have to implement a calculator which can perform addition, subtraction, multiplication, and division. Problem Statement# Write a Java class called Calculator with ● private fields: ○ num1 and num2 (double type) And methods: ● add(), a method which returns the addition of two numbers ● subtract(), a method which returns the subtraction of num1 from num2 ● multiply(), a method which returns the multiplication of numbers ● divide(), a method which returns the division of num2 by num1 ● Define a parameterized constructor which takes two parameters num1 and num2 and assigns these variables to the respective fields in the class. Input# Pass double point numbers in the parameterized constructor Output# addition, subtraction, division, and multiplication Sample Input# Calculator obj = new Calculator(10, 94); obj.add() obj.subtract() obj.multiply() obj.divide() Sample Output# 104 84 940 9.4 Part of the Solution class Calculator { // write class fields here public Calculator(double num1, double num2) { //write definition here } double add() { //write definition here return 0; } double subtract() { //write definition here return 0; } double multiply() { //write definition here return 0; } double divide() { //write definition here return 0; } } class Demo { public static void main(String args[]) { Calculator obj = new Calculator(10, 94); System.out.println(obj.add()); System.out.println(obj.subtract()); System.out.println(obj.multiply()); System.out.println(obj.divide());
