Hints

• A good starting point is to read my sample program BankAccount.java and BankAccountTest.java .
• You have to think of what member variables you need and what constructors you need in class Book
• Use String class to implement the methods doesAuthorContain and doesTitleContain . If you can find the right methods to use, it just take few lines to finish the implementations. You should  refer to String doc . To search a string in another string refer to the methods name indexOf.
• The booklist is already in an array format. You should read my notes on array of arrays .
• Read my notes on how to use args in the main function, you can read a sample program here .
