Suppose you have a pre-existing class Height that keeps track of a height in feet and inches. The class has the following data and constructor: Field/Constructor private String description private int feet private double inches Description W Describes the type of height, one of "Building, "Person, and "Tree". W Number of feet (always > 0) public Height(String description, int constructs a Height object with the given description, and number of feet and inches. Throws an exception if description is not one of "Building", "Person" and "Tree", or if feet or inches are negative, or if inches is greater than or equal to 12. feet, int inches) Number of inches (always 0 and <12) Your task is to modify the class to be comparable by adding an appropriate compareTo method. Height objects of different heights are just compared by height irrespective of their description. That is a Height object ("Person", 6 feet, 2.5 inches) is considered greater than a Height object ("Tree", 4 feet, 3.6 inches). Height objects of the same height are compared by their description. For the same height, "Building" Height objects are greater than "Tree" Height objects, and "Tree" Height objects are greater than "Person" Height objects. If two Height objects have the same description and the same height (i.e. same number of feet and inches), they are considered equal. Your method should not modify any Height object's state. You may assume that the parameter passed is not null. . to contain an override of the equals method from Object (public boolean equals(Object obj)). As stated in the compareTo question, two Height objects are considered equal if they have the same description and the same height. to contain an override of the hashCode method from Object (public int hashCode()). The return value of the hashCode method of an object is used to compute the index of the location of the object in a hash table. Write the three methods compareTo, equals and hashCode below.
