I have Implement a class Natural Number that represents Postive Integer (x>=0). The class only attribute is Int x. Implemented a constructor that throws exception ErrConstrException if the value of the argument less than 0(x<0). Created a method called void minus(NautralNumber x) that subtracts x from the calling object. It throws exception ErrModifException if the result is less than zer0((y-x) < 0). ErrConstrException and ErrModifException are class that inherit from exception class. There's a driver class that creates an array of NaturalNumber; it can sotre 10 objects of same type. Moreover, the Implementation of the code is tested in this class.
