- **Java Programming** Consider a system which manages a library for the students and books details. The details of library are name and location. The library has many books and students. The operations of library are list of students which prints the list of students names, no of students which prints the total no of students in library, list of books which prints the title of books and no of books which prints the total no of books in the library. The detail of each student is name, id, batch and semester. The operations of students are add student which add the student to the library, view student which prints the details of the student and assign book which add the book id in the details of the student. The book has two types course books and knowledge books. The common fields of both books are title, author, publisher, issue date and issued. The detail of course book has one more field semester.
