CST 8284 Assignment 1 (due Feb 12, total of 65 marks) The goal of this lab is to create a sub-class in Java, and use inheritance, super, and override. I am giving you some code to start the assignment. You must create each of the following objects: Integer, Rational, and Complex, which must be added to the package assignment1, which already exists I have also created a class called Test, which is in the testing package. This class has a main method which has many lines of code which test the various functions that you will implement Your task is to write the Integer, Rational, and Complex classes so that the tests in the main method all pass. You should also write the JavaDoc comments for the three classes, and create the UML diagrams 1) Integer should be a class that has a single int variable. This class must inherit from Object, and have its own variable, you can not use the Integer class that is already included in the Java language 2) Rational should be a class that inherits from Integer, but has a second integer variable to represent the denominator. Rational numbers are a special kind of number that can be represented as a fraction, in the form a/ b. For example, 2.75 can be written as (275/ 100) or (11/4). The number pi 3.1415926535 is an irrational number, meaning that it can not be written as a fraction a b 3) A complex number is a number that contains both real and imaginary Rational components. The imaginary component, shown by letter i, represents V-1. For this assignment, Complex should extend Rational, and the inherited variables should represent the real component of the number. Complex should then have a new variable, of type Rational, to represent the imaginary component For all three classes, implement the following methods * Empty constructor, Default constructor, Copy constructor, equals clone toString add subtract multiply divide
