Question

Look at the following partial class definition, then respond to the questions that follow it: public class Book { private String title; private string author; private string publisher; private int copiesSold; } Write a constructor for this class. The constructor should accept an argument for each of the fields.

Answer 1

I will code in Java.

public class Book {

private String title;

private String author;

private String publisher;

private int copiesSold;

//the constructor method accepts the parameters for each field.

public Book(String title, String author, String publisher, int copiesSold){

//each parameter is set to each field of the class.

this.title = title;

this.author = author;

this.publisher = publisher;

this.copiesSold = copiesSold;

}

}
