Calculator class In the file Calculator. java, write a class called Calculator that emulates basic functions of a calculator: add, subtract, multiply, divide, and clear. The class has one private member field called 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:
The initial value of the instance field, value
The value after adding num1
The value after multiplying by 3
The value after subtracting num2
The value after dividing by 2
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
