Question 20, 21 & 22:

public class Book {
   private String title;
   private String author;
   private int isbn;
   private int yearPublished;
   Book(String title, String author, int isbn,int yearPublished){
       this.title = title;
       this.author = author;
       this.isbn = isbn;
       this.yearPublished = yearPublished;
   }
   public Book(Book b){
       this.title = b.title;
       this.author = b.author;
       this.isbn = b.isbn;
       this.yearPublished = b.yearPublished;
   }
   public int getYearPublished() {
       return yearPublished;
   }

   public void setYearPublished(int yearPublished) {
       this.yearPublished = yearPublished;
   }

   public String getTitle() {
       return title;
   }

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

   public String getAuthor() {
       return author;

   public void setAuthor(String author) {
       this.author = author;
   }

   public int getIsbn() {
       return isbn;
   }

   public void setIsbn(int isbn) {
       this.isbn = isbn;
   }

   public void display(){
       System.out.println("Title : "+title+" Author : "+author+" ISBN : "+isbn);
   }
}

int sum = 0;

for(int i=0; i<a.length; i++) {

sum = sum + a[i];

}

return sum;

}
