Assume the availability of an existing class, ICalculator, that models an integer arithmetic calculator and contains: an instance variable currentValue that stores the current int value of the calculator methods add, sub, mul, and div Each method in ICalculator receives an int argument and applies its operation to currentValue and returns the new value of currentValue. So, if currentValue has the value 8 and sub(6) is invoked then currentValue ends up with the value 2, and 2 is returned. So, you are to write the definition of a subclass, ICalculator1, based on ICalculator. The class ICalculator1 has one additional method, sign, that receives no arguments, and doesn’t modify currentValue. Instead, it simply returns 1, 0 or -1 depending on the whether currentValue is positive, zero, or negative respectively.
