the "add book function" can be displayed and can be borrowed and returned, it will take a String title,author,publisher and an int book id. but i still don't have any idea on starting this part of my code.

A method can not be displayed. It can display data that is in the program.
That description sounds more like what a Book is, not what the add() method will do. A book can be displayed, borrowed and returned.
What class will the add() method be in? You have posted several classes.


Are those the arguments that would be passed to the add() method.
What would the add() method do with those pieces of data?

sorry bout that. add() method will we in a separate class, and it will accept data from the user such as the string name,author,publisher and int ID. and the add() method would store these data's in an array.

i want my addBook() method in a separate class like my other methods in my program,
the array should be on the Library class of my code,
yes data must be put in a class before the addBook() method stores it to the array,
the addBook() method will accept data by using dialog boxes only,
yes, the data's added will also be used in my searchBook(), rentBook(), and returnBook() methods,

and also can i make a constructor for an array? if so how?

yes the addBook() method will be in my Library class,

ah i see but can i turn this piece of code to an array?

Book book1 = new Book("Hunger Games");
    Book book2 = new Book("Catching	Fire");
    Book book3 = new Book("Mocking Jay");
    Book book4 = new Book("The Da Vinci	Code");
    Book book5 = new Book("Harry Potter	and	The	Sorcerer's Stone");
    Book book6 = new Book("Harry Potter	and	The	Chamber	of Secrets");
    Book book7 = new Book("Harry Potter	and	The	Prisoner of	Azkaban");
    Book book8 = new Book("Harry Potter	and	The	Goblet of Fire");
    Book book9 = new Book("Harry Potter	and	The	Order of The Phoenix");
    Book book10	= new Book("Harry Potter and The Half-blood	Prince");
    Book book11	= new Book("Harry Potter and The Deathly Hallows");

Sure you can, is an array right for you? Does an array provide the kind of storage and access you need? I would vote for some type of grouping vs a bunch of same-name-numbered variables, it is up to you to decide what suits your needs.

an ArrayList maybe? but how?

Well that sounds like another option.
Why don't you try them and see?
There are plenty of Array and ArrayList usage examples on the web.

if i do that the type would be "Book" not string,

Originally Posted by jaydac12

Is that going to be a problem in your project?

yes because i will be needing it to be in inside my if condition using equalsIgnoreCase()

i want to compare it to string,
but how am i going to make an array of the Book class?

so that the user could input a book and the searchBook() method would find matches in the array,

yes i know how to define an array, so it would be like this?
Book[] bookName = new Book[10];

so the type would be "Book" so it's not comparable to String?

the purpose of the comparison is to find matches in the array,
and the String contains the user's input
