Create a Java program that simulates a simple library book tracking system. The library has a fixed number of books, and the program should allow the librarian to view, update, and search the books. The program must utilize one-dimensional arrays to manage the information. Most of the requirements have been fulfilled. Starter code is given. Fill in what is missing
Example Output:
Welcome to Library Book Tracker!
1. View Catalog
2. Search Book
3. Add Book
4. Exit
Select an option: 1
Book Catalog:
1. Moby Dick
2. The great Gatsby
3. To kill a mockingbird
...
Select an option: 2
Enter book title to search: Moby Dick
Book found at position 1!
Select an option: 5
Goodbye!
