    Default Can anyone help me with java code

    Hi everyone

    I am writing a simple java code Library class and Book class. I have hard time to write the code to return a book after borrowing it. I need help. This is my code

    #########################Book class################################
    package Library;

    public class Book {
    String title;

    boolean borrowed = false;
    //borrowed = false;

    // Creates a new Book
    public Book(String bookTitle) {
    title = bookTitle;
    }
    // Marks the book as rented
    public void borrowed() {
    borrowed = true;
    }
    // Marks the book as not rented
    public void returned() {
    borrowed = false;
    }
    // Returns true if the book is rented, false otherwise
    public boolean isBorrowed() {
    if (borrowed)
    return true;
    else
    return false;
    }
    // Returns the title of the book
    public String getTitle() {
    return title;
    }
    }

    ##############################Library class###################################

    package Library;

    public class Library {
    String address;
    String title;

    public Book myBook;

    Library(String streetname) {
    address = streetname;
    }

    String[] tmp = new String[4];
    int bookcount = 0;

    //adding book
    public void addBook(Book book) {
    tmp[bookcount] = book.getTitle();
    bookcount++;
    }

    //Library hours
    public static void printOpeningHours() {
    System.out.println("Libraries are open daily from 9am to 5pm.");
    }

    //Library address
    public void printAddress() {
    System.out.println(this.address);
    }

    //Avaiable book
    public void printAvailableBooks() {
    for (int j = 0; j < bookcount; j++)
    {
    System.out.println(tmp[j]);
    }
    }

    //borrowed book
    public void borrowBook(String title) {
    for (int i = 0; i < bookcount; i++)
    {
    if (tmp[i].equals(title))
    tmp[i] = "";
    }
    }

    //returning book -----> I have trouble here
    /* public void returnBook(String title) {

    for (int i = 0; i < bookcount; i++)
    {
    if (tmp[i].equals(title))
    System.out.println("Your book is from other library. ");
    else

    }
    }*/

    public static void main(String[] args) {
    // Create two libraries
    Library firstLibrary = new Library("10 Main St.");
    Library secondLibrary = new Library("228 Liberty St.");

    // Add four books to the first library
    firstLibrary.addBook(new Book("The Da Vinci Code"));
    firstLibrary.addBook(new Book("Le Petit Prince"));
    firstLibrary.addBook(new Book("A Tale of Two Cities"));
    firstLibrary.addBook(new Book("The Lord of the Rings"));
