Q$3\mathrm{.}4$: Assume you are asked to write a simple JAVA class Borrower representing a library user. Your program needs to manage the books borrowed from the university library.

a$)$ Write a Java class to represent a Borrower. This class should contain instance variables to hold the following pieces of information. Be careful to choose the best types to hold this information.

$[4$ Marks$]$

The name of the Borrower $($both first name and last name$).$

The index number of student library card.

The number of books that the student is currently borrowing.

The total number of books that have been borrowed by the student.

$[4$ Marks$]$

c$)$ Write a new class called Borrowers, which contains a single instance variable $-$ an array of all the students in the class. In its constructor, please use the array with instances of your Borrower class to hold information on the following students:

$[6$ Marks$]$

$\backslash$table$[[$First Name,Last Name,Card number$],[$Sidong$,$Wang,$001],[$Miao$,$Li$,002],[$Tian$,$Zhang,$003]]$
