"It doesn't work" is probably the most useless problem report we get - and we get it a lot. It tells us nothing about what is happening, or when it happens.
So tell us what it is doing that you didn't expect, or not doing that you did.
Tell us what you did to get it to happen.
Tell us any error messages.
Use the "Improve question" widget to edit your question and provide better information.

Solution 1

Java

Book b = new Book(bookId, tittle, authorSurname, authorName, purchaseDate, status) {
}; // to implement all abrstract method

What are those braces supposed to be for on this constructor call?
