Question

PLEASE DO IN JAVA

1) Create interface named “Person” which exposes getter/setter methods for the person’s name and college ID: 1. getName 2. setName 3. getID 4. setID. The college ID is represented as “int”. Define two classes, Student and Faculty, which implement Person. Add field GPA to Student and department to faculty. Make them private and create corresponding getters (getGPA, getDepartment) and setters (setGPA, setDepartment). Use appropriate types.

2) Write a class College, which contains the name of the college and a single private array that can store up to 100 students and faculties. Write the following methods: 1. addPerson: takes a student or a faculty as parameter and adds it to the college 2. setName: and getName: get and set the name of the college

3) Add the following method to College: 1. sort(): moves all students to the first positions of the array, and all faculties after that. As an example, let fn indicate faculty n and sn indicate student n. If the array contains s1|f1|f2|s2|s3|f3|s4, after invoking sort the array will contain s1|s2|s3|s4|f1|f2|f3 (this does not have to be done “in place”). Students and faculty are sorted by last name. You can use any number of auxiliary (private) methods, if needed.

4) Add a method storeCollege(String filename) to College. This method saves all the college information in a file (name specified in variable filename). Use ObjectOutputStream and write one single object. Add method loadStoreCollege(String filename) which loads the information written by storeCollege.

5) Add the program’s main method to College. The main method instantiates a new College, adds some faculty and students in random order (populated with their name and ID), sorts them using the code in Part 3, and stores them into a file. It then instantiates a new college that loads the data previously written to file, and verifies that the first and second college contain identical data. The main method does not ask for any input from the terminal.

Answer 1

thanks for the question, please post only 1 question at a time. As per Chegg policy, we are limited to answering only the first question. I have solved Question 1 and Question 2.

Please post question 3,4 and 5 as a separate post and I will solve the rest. Sorry for the inconvenience caused here.

Here are the 4 files you will be needing as part of Question 1 and 2
