Hibernate: Writing POJO Class

The first step is to create a Java POJO class. We consider a simple class Book as follows:

//Book.java public class Book { private int b_id; private int b_price;

private String b_title; public Book(){}

public Book(String t, int p) {

this.b_title = t; this.b_price = p;

}

public int getId() { return b_id; }

public void setId(int id )      { this.b_id = id; }

public String getTitle() { return b_title; }

public void setTitle(String t ){ this.b_title = t; }

public int getPrice() { return b_price; }

}
public void setPrice(int p ) { this.b_price = p; }

This contains three private fields b_id, b_price and b_title and get and set methods for these fields. The b_id field works like an index, whereas b_titie and b_price fields store the title and price of a book respectively. It is a good idea to write a class in hibernate as JavaBeans compliant class.
