- 1. Objective: Create a graphical database for a library IN JAVA. It should display the information of every book in the library system. Each book should have the following information: Name Author(s) Year published Publisher ISBN Page Count The system should be able to perform the following operations: Display books in alphabetical order Either all books or the books that met a search criteria noted below Add a book Remove a book Search books based on Name Author Year Publisher ISBN Load a library database file Save a library database file Solution import java.io.BufferedReader; import java.io.File; import java.io.FileInputStream; import java.io.FileNotFoundException; import java.io.FileWriter; import java.io.IOException; import java.io.InputStreamReader; import javax.swing.JFileChooser; import javax.swing.table.DefaultTableModel; public class Library extends javax.swing.JFrame {
