1. Define 1 argument constructor for Java for book
  2. Define toString method for title, and a testor method
  3. Generate unique id for class
  4. Create a public getter that has a book count
  5. Define tester method that intializes st least 2 books, outputs id and title, and provides a count of books in library
public class Book
{
    String = title; 
    double = id; 
    int = numberOfBooks;
    int1 = book1;
    int2 = book2;

    String () = booktitle;
    {
        public Book (title)
        {
            double bookCount = int1 + int2;
            this.get = bookCount;

        }
    
        public void toString 
        {
            this.get = bookCount;
            this.generate 
        }
    }
            System.out.println("There are two books in the library");
            System.out.println("")
            System.out.println("The number of books is" +bookCount "in the library");
    return bookCount; 
}
