Build a class called Calculator that emulates basic functions of a calculator: add, subtract, multiply, divide, and clear. The class has one private member field, double value, for the calculator's current value. Implement the following Constructor and instance methods as listed below: public Calculator() - Constructor method to set the member field to 0.0 • public void add(double val) - add the parameter to the member field • public void subtract(double val) - subtract the parameter from the member field • public void multiply(double val) - multiply the member field by the parameter • public void divide(double val) - divide the member field by the parameter • public void clear() - set the member field to 0.0 • public double getValue() - return the member field Given two double input values num1 and num2, the program outputs the following values: 1. The initial value of the instance field, value 2. The value after adding num1 3. The value after multiplying by 3 4. The value after subtracting num2 5. The value after dividing by 2 6. The value after calling the clear() method Ex: If the input is: 10.0 5.0 the output is: 0.0 10.0 30.0 25.0 12.5 0.0
