Listing 1-6. Model: Author

package com.apress.books.model;

public class Author {
private Long id;
private Long bookId;
private String firstName;
private String lastName;

public Long getId() {
return id;
}

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

public Long getBookId() {
return bookId;
}

public void setBookId(Long bookId) {
this.bookId = bookId;
}

public String getFirstName() {
return firstName;
}

public void setFirstName(String firstName) {
this.firstName = firstName;
}

public String getLastName() {
return lastName;
}

public void setLastName(String lastName) {
this.lastName = lastName;
}

public String toString() {
return "Author - Id: " + id + ", Book id: " + bookId + ", First Name: "

• firstName + ", Last Name: " +lastName;
  }

}
