I have a variable "book" which askes the user for four titles which will be
with one patron's name.
How would i load this with a loop?
Some how I am getting lost?
Thank you.

input Patron's name
name = reader.readLine("Enter the first patron's name: ");
patron.setName(p);
for (int i = 1; i <= 3; i++){
Book = reader.readLine("Enter the book's title: ");
Book.setBook(i, Book);

On the line that reads:

patron.setName(p);

Shouldn't is be:

patron.setName(name);

I have been attempting to modify this program below to accept user input for
patron's
name and book's title:

public class LibraryTester{

public static void main (String[] args)

{

Patron p = new Patron("Ken Lambert");

Book b1 = new Book("Cider House Rules", "John Irving");

Book b2 = new Book("The Perfect Storm", "Sebastian Junger");

Book b3 = new Book("The Illiad", "Homer");

Book b4 = new Book("Hamlet", "William Shakespeare");

System.out.println(p.borrowBook(b1));

System.out.println(p.borrowBook(b2));

System.out.println(p.borrowBook(b3));

System.out.println(p.borrowBook(b4));

System.out.println(p);

System.out.println(p.returnBook("Cider House Rules"));

System.out.println(p.hasBook("Cider House Rules"));

System.out.println(p.hasBook("The Perfect Storm"));

System.out.println(p);

}

}

**********************************************

to pass data to another two programs, this one is Book:

public class Book {

//instance varibles

private String author, title;

//construction method

public Book()

{

author = " ";

title = " ";

}

//another constructor method - same name

public Book(String author, String title)

{

author = author;

title = title;

}

public String author()

{

return(author);

}

public String title()

{

return(title);

}

public String toString()

{

return("Title: " + title + "n" + "Author:" +
author);

}

}

****************************************************

And pass to this program Patron:

public class Patron {

//instance varibles

private String name;

private Book Book1, Book2, Book3;

//constructor method

public Patron()

{

name = " ";

Book1 = null;

Book2 = null;

Book3 = null;

}

public void setName(String nm){

//Set a student's name

name=nm;

}

public String getName()

{

return(name);

}

public boolean borrow(Book B)

{

if (Book1 == null)

{

Book1 = B;

return(true);

}

else if (Book2 == null)

{

Book2 = B;

return(true);

}

else if (Book3 == null)

{

Book3 = B;

return(true);

}

else

return(false);

}

public boolean hasbook(String title)

{

if (Book1 !=null)

if
(Book1.title().equals(title))

return(true);

if (Book2 !=null)

if
(Book2.title().equals(title))

return(true);

if (Book3 !=null)

if
(Book3.title().equals(title))

return(true);

return(false);

}

public boolean returnbook(String title)

{

if (Book1 !=null)

if
(Book1.title().equals(title))

{

Book1 = null;

return(true);

}

if (Book2 !=null)

if
(Book2.title().equals(title))

{

Book2 = null;

return(true);

}

if (Book3 !=null)

if
(Book3.title().equals(title))

{

Book3 = null;

return(true);

}

return(false);

}

public String toString()

{

String str;

str = ("Patron's name: " +
name);

if (Book1 != null)

str = (str +
"n" + Book1);

if (Book2 != null)

str = (str +
"n" + Book2);

if (Book3 != null)

str = (str +
"n" + Book3);

return(str);

}

}

//ends patrons class

I have rewritten my LibraryTester at least 11 times in vain.

Any comments will be greatly appreciated.

Thank you.

[snip for readablility]
My first 18 - 20 attempts to re-code LibraryTester to accept user input was:

import TerminalIO.KeyboardReader;

import java.text.NumberFormat;

import BreezySwing.Format;

public class LibraryTester {

public static void main (String[] args){

// Instantiate the Patrons & Books and the keyboard

Patron patron1 = new Patron();

Patron patron2 = new Patron();

Patron patron3 = new Patron();

//Book b1 = new Book();

//Book b2 = new Book();

//Book b3 = new Book();

KeyboardReader reader = new KeyboardReader();

String name;

String book;

// Input the first patron's data

name = reader.readLine("Enter the first patron's name: ");

//patron1.setName(name);

for (int i = 1; i <= 3; i++){

book = reader.readLine("Enter the book's title: ");

student1.setBook(i, book);

}

// Input the second patron's data

name = reader.readLine("Enter the second patron's name: ");

patron2.setName(name);

for (int i = 1; i <= 3; i++){

book = reader.readLine("Enter the book's title: ");

patron2.setBook(i, book);

}

// Input the third patron's data

name = reader.readLine("Enter the third patron's name: ");

patron3.setName(name);

for (int i = 1; i <= 3; i++){

book = reader.readLine("Enter the book's title: ");

patron3.setBook(i, book);

}

// Output the three patrons information

System.out.println(patron1);

System.out.println(patron2);

*****************************************

I know that I am missing a piece somewhere. Between my wife complaining the
kitchen table is

cluttered with all my java info, books, print outs, and other research stuff
for the last week, I am starting

to believe that I don't understand how to pass info in java.

Any comments, directions, would be greatly appreciated.

Thank you very much for all those that take a minute to review my kaos.
