import java.lang.*;
public class Test{
public static void main(String[] args){
Book book = new Book("111", "name", "publisher", 1);

book.PrintBookMessage();

System.out.println("Book NO:" + book.GetBookNumber() + "\n" + "Book name:" + book.GetBookName() +
"\n" + "Publisher name:" + book.GetPublisherName() + "\n" + "Store:" + book.GetStore());
}
}

class Book{
private static String strBookNumber;
private static String strBookName;
private static String strPublisherName;
private static int nStore;

public Book(){
strBookNumber = null;
strBookName = null;
strPublisherName = null;
nStore = 0;
}

public Book(String strBookNumber, String strBookName, String strPublisherName, int nStore){
this.strBookNumber = strBookNumber;
this.strBookName = strBookName;
this.strPublisherName = strPublisherName;
this.nStore = nStore;
}

public void SetBookName(String strBookName){
this.strBookName = strBookName;
}

public String GetBookName(){
return this.strBookName;
}

public void SetBookNumber(String strBookName){
this.strBookNumber = strBookNumber;
}

public String GetBookNumber(){
return this.strBookNumber;
}

public void SetPublisherName(String strPublisherName){
this.strPublisherName = strPublisherName;
}

public String GetPublisherName(){
return this.strPublisherName;
}

public int GetStore(){
return this.nStore;
}

public void SetStore(int nStore){
this.nStore = nStore;
}

public void PrintBookMessage(){
System.out.println("Book NO:" + this.strBookNumber + "\n" + "Book name:" + this.strBookName +
"\n" + "Publisher name:" + this.strPublisherName + "\n" + "Store:" + this.nStore);
}
}
