Question
You will write two classes for program 7. Please submit all classes in one file. The name of the physical program file submitted xxxx_program7.
Assignment: A veterinarian services many pets and their owners. As new pets are added to the population of pets being serviced, their information is entered into a flat text file. Each month, the vet requests a listing of all pets. You have to write a program to produce a report of animals and their owners from the data in the flat text file. Below is a description of the information on the text file:
? The first line on the file contains the number of animals on the file (numeric). It can be used to determine the size of the array. Your program should work for any number of Animals.
? The fields below repeat for each animal:
o Owner name (String)
o Birth year (numeric)
o Bill balance (numeric)
o Species (String)
Program requirements and grading:
From the information provided, write a solution that includes the following:
? An Animal class which includes:
o Instance variables (4 points)
o 2 Constructors (10 points)
o Accessor and mutator methods (16 points)
? Write a class xxxx_program7 which utilizes the following:
o An Array of Animal objects (5 points)
o A method which reads the input file provided and stores the objects in the array of Animals. (10 points)
o A method that formats and prints the output report. Please do not use a toString() method but rather call the getters of the Animal class to print the report. (7.5 points)
o The main method will call all the other methods which will: (7.5 points)
? Read the text file and store the objects in the array
? Format and print the report
? Test the program so that there are no errors using the input file provided, program7.txt. Note that the program will only be tested using the file posted on Blackboard. You should not submit another file. (10 points)
? Submit your program in one file, xxxx_program7, where xxxx is your Kean email id. (5 points)
