Help on ArrayList of Objects
Hello everyone, I am doing a project for university and I抦 having troubles with a method. I try to explain what it is?br>
I have two classes, one is a book class and the other is a catalogue which uses an ArrayList. Each book has a String description and a borrower number.
I have to do a method to search trough the books, but only if the search found ONE book I should be able to borrow that book, by changing the borrower number, which is set to 0 by default.
Can somebody give me a tip?
There is it the code.
public class Book
{
private String description;
private int borrowerNumber;
public Book(String theDescription)
{
borrowerNumber = 0;
description = theDescription;
}
public void print()
{
System.out.println(description);
}
public String getDescription()
{
return description;
}
public int getBorrowerNumber()
{
return borrowerNumber;
}
}
import java.util.ArrayList;
public class Catalogue
{
private ArrayList<Book> books;
private String entry;
private int borrower;
private int searchNumber;
private int yourID;
public Catalogue()
{
books = new ArrayList<Book>();
// searchNumber = 1;
}
public void addBook(String description)
{
books.add(new Book(description));
}
public void Search(String entry, int borrower)
{
searchNumber = 0;
for(Book book : books){
if (book.getDescription().equals(entry) || book.getDescription().contains(entry)){
System.out.println(searchNumber++ + " " + book.getDescription()); }
if (book.getBorrowerNumber() == 0 && book.getDescription().equals("")){
System.out.println(searchNumber+1 + " " + book.getDescription());}
if (book.getBorrowerNumber() == borrower && book.getBorrowerNumber() != 0){
System.out.println(searchNumber+1 + " " + book.getDescription());}
if (searchNumber > 0){
System.out.println("please search better");}
else{
book.getBorrowerNumber()= borrower;}
}
