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
Given Code:

public class LibraryBookTracker {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
String[] bookCatalog = {

"Pride and Prejudice", "1984", "Brave New World",
"The Catcher in the Rye", "Lord of the Rings", "Harry Potter and
the Sorcerer's Stone",
"Animal Farm"
};
int capacity = bookCatalog.length;
while (true) {
System.out.println("Welcome to Library Book Tracker!");
System.out.println("1. View Catalog");
System.out.println("2. Search Book");
System.out.println("3. Add Book");
System.out.println("4. Remove Book");
System.out.println("5. Exit");
System.out.print("Select an option: ");
int choice = scanner.nextInt();
scanner.nextLine(); // Consume the newline character
