Assignment For this assignment you will write a class DogWeight which is a subclass of the Weight class which was written for the fourth assignment. It represents a weight of a domesticated dog. I have provided a template for the class found in the DogWeight.java file as well as a starting file Weightjava, both of which are posted to D2L. You should begin your assignment by downloading that template, and you should note that the Weight class is slightly different than the one you may have written for the fourth assignment. Please start with my Weight.java file not your own. Note that I have also provided a test program called TestWeight.java. You will need all three files to complete this assignment, although you will only submit the DogWeight.java file The DogWeight class has a single static variable numDogs that represents the number of DogWeight objects in existence. It also has four constants, one each for the maximum weight in pounds and kilograms and the minimum weight in pounds and kilograms. You are not allowed to create any extra variables in the class, other than variables local to the methods You will complete the assignment by writing the following methods for the DogWeight class 1. public DogWeight0: The default constructor first calls the Weight constructor in order to set the dog's weight to 10 pounds. Note: It should NOT set either scale or wValue directly. These should be set using a call to the Weight constructor. Once the Weight constructor has been called, it should modify the number of DogWeight objects appropriately. This will have to be done directly 2. public DogWeight(double initW, char initS): The constructor first checks if initS is valid, e.g. is one of p'or 'k' in either capitalization. If it is, it uses initS to set scale. Otherwise it sets scale to 'p' or 'P (pick one!) Then the constructor sets the dog's weight measurement. If the scale is pounds, it checks that initW is less than or equal to MAXP and greater than or equal to MINP. If it is, it uses initW to set wValue. Otherwise it sets wValue to MINP. If the scale is kilograms, it does a similar check except it uses MAXK and MINK and uses MINK as the default. It also modifys the number of DogWeight objects appropriately 3. public String toString0: The method returns the numeric weight to 2 decimal places and labeled with whatever scale is currently used in the object. Note that you will need to have an if statement to check the char scale and return the correct String based on what you find in scale. See the examples below for specific information about what should be displayed in each case 4. public boolean equals(DogWeight other): This method returns true if the current Dog Weight object and other have the same value when considered in the same scale and false otherwise. For full credit you are required to either use getK or getP in this method in order to obtain a measurement for each object. Solutions that duplicate the code found in getK and getP will not earn full credit, even if completely correct. 5. public static int getNumDogs0: This method returns the number of DogWeight objects that have been created. It does so by returning the value of the static variable that tracks the number of DogWeight objects I have provided a driver program (e.g. a main method that uses the DogWeight class) TestWeight.java to help you test your code which has been posted to D2L. Be aware that the grader may add to that program when grading, so if you feel that any of you modify as necessary. However, you should only submit the DogWeight.java class r methods haven't been tested effectively by the driver program, please Below you can see the sample output produced by the TestWeight class when it is run in conjunction with a correctly completed DogWeight class. Note that you wil need to use two packages for this assignment: wt to hold the Weight.java and DogWeight.java files and hw6 to hold the TestWeight.java file. DO NOT change the name of these packages-- use the ones I have specified
