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. Only add to the part where says your code goes here.
Given Code:
import java.util.Scanner;
public class LibraryBookTracker {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
String[] bookCatalog = {
"Moby Dick", "The Great Gatsby", "To Kill a Mockingbird",
"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
switch (choice) {
case 1:
viewCatalog(bookCatalog);
break;
case 2:
searchBook(scanner, bookCatalog);
break;
case 3:
addBook(scanner, bookCatalog, capacity);
break;
case 4:

case 5:
System.out.println("Goodbye!");
scanner.close();
return;
default:
System.out.println("Invalid option. Please select a valid
option.");
}
