Look at the following partial class definition, and then respond to the questions that follow it: public class Book

{

private String title;

private String author;

private String publisher;

private int copiesSold;

}

a. Write a constructor for this class. The constructor should accept an argument for each of the fields.

b. Write accessor and mutator methods for each field.

c. Draw a UML diagram for the class, including the methods you have written.

Solution :

a.

public Book(, String author, , int ) {

 this. = ;

 this. = ;

 this. = ;

 this. = ;

b). getTitle() {

 return ;

}

setTitle() {

 this. = ;

}

getAuthor() {

 return author;

}

setAuthor(String author) {

 this. = ;

}

getPublisher() {

 return ;

}

setPublisher(String ) {

 this. =;

}

public int get() {

 return ;

}

set(int ) {

 this. = ;

}
