modify the Book class to accommodate multiple authors using one of the components from the Java Collection Framework. Can you help? Thanks! (Please only answer in Java codes) I just noticed that I need to revise the boolean equals. and validate part since they are not right? I'm so lost!!!

Here is the codes that I already have for class Book:

package book;

public class Book {

private String author;

private String title;

private String isbn;

public Book() {

super();

isbn="";

author="";

title = "";

}

public Book(String author, String title, String isbn) {

this.author = author;

this.title = title;

this.isbn = isbn;

}

public String getAuthor(){

return this.author;

}

public void setAuthor(String author) {

this.author = author;

}

public String getTitle(){

return this.title;

}

public void setTitle(String title) {

this.title = title;

}

public String getIsbn() {

return this.isbn;

}

public void setIsbn(String isbn) {

this.isbn = isbn;

}

public boolean equals(Object obj) {

Book book = (Book) obj;

return this.getAuthor().equals(getAuthor()) && (this.getIsbn().equals(getIsbn())) && (this.getTitle().equals(getTitle()));

}

public boolean validate(){

return (this.getIsbn().trim()!= null) && (this.getAuthor().trim()!= null) && (this.getTitle().trim()!=null);

}
