Use the attached UML diagrams to build up your project classes
Make sure to put view for your project by Entering true data
You will need to add 5 books and 5 students and at least 3 LibraryIssues
LibraryIssues keeps track of the borrowed book
The librray uses all classes as mentioned in the UML diagram
You will need to check if book is available before borrowing it.
searchLibrrayIssueByStuent(Student): List
This method returns all book if borrowed by single student, as a student could borrow more than one book
Static NUMBEROFBOOKS: int
Each time you add a book the static variable is increased and Each time a book is removed so the static variable is decreased.
createLibraryIssue(LibraryIssue) : boolean
changed the Boolean variable status in book element to false and return false if book is not available
removeLibrrayIssue(LibraryIssue):Boolean
changed the Boolean variable status in book element to true and return false if book is available
Note
LibrrayIssue and Book in the class Library should be List or map
Do not use array as the size is not fixed
