Soal:
1. Apa yang dimaksud dengan Inheritance dalam Java. Bagaimana implementasi inheritance dalam Final Project yang sedang dikerjakan.
2. Jelaskan fitur Aplikasi yang ada dalam Final Project
3. Buatlah desain Diagram Kelas dari aplikasi Final Project
Jawaban:
1. Pewarisan (inheritance) adalah salah satu konsep dasar dalam pemrograman berorientasi objek (OOP) yang memungkinkan sebuah kelas (kelas turunan atau subclass) untuk mewarisi atribut dan metode dari kelas lain (kelas induk atau superclass). Dengan pewarisan, kita dapat menciptakan hierarki kelas yang lebih terstruktur dan meminimalkan pengulangan kode. Implementasi inhertance dalam FP yang kelompok kami kerjakan menggunakan library JFrame untuk menampilkan tampilan pada java
class BookDetailsPage extends JFrame {
public BookDetailsPage(Book book) {
setTitle("Book Details - " + book.getTitle());
setSize(600, 400);
setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
setLayout(new BorderLayout(10, 10));
// Panel Gambar Cover
JLabel coverLabel = new JLabel(createImageIcon(book.getImagePath()));
coverLabel.setHorizontalAlignment(SwingConstants.CENTER);
add(coverLabel, BorderLayout.NORTH);
String description = book.getDescription();
String formattedDescription = description.replace("\n", "<br>");
// Panel Informasi Buku
JEditorPane bookInfoPane = new JEditorPane("text/html",
"<html>" +
"<b>Title:</b> " + book.getTitle() + "<br>" +
"<b>Author:</b> " + book.getAuthor() + "<br>" +
"<b>Year:</b> " + book.getYear() + "<br>" +
"<b>Genres:</b> " + String.join(", ", book.getGenres()) + "<br><br>" +
"<b>Description:</b><br>" + formattedDescription +
"</html>"
);
Extends JFrame
BookDetailsPage adalah kelas yang mewarisi JFrame.
JFrame adalah sebuah kelas dalam pustaka Java Swing yang menyediakan jendela utama untuk aplikasi grafis berbasis GUI. Kelas ini digunakan untuk membuat antarmuka pengguna berbasis jendela yang dapat menampilkan komponen grafis seperti tombol, label, dan lainnya.
Dengan mewarisi JFrame, kelas BookDetailsPage dapat memiliki seluruh fungsionalitas yang disediakan oleh JFrame, seperti pengaturan ukuran jendela, penutupan jendela, pengaturan layout, dan menambahkan komponen UI.
2. Fitur yang ada meliputi
Searching Data
searchButton.addActionListener(e -> {
String query = searchField.getText().toLowerCase();
gridPanel.removeAll();
for (Book book : books) {
if (book.getTitle().toLowerCase().contains(query) || book.getAuthor().toLowerCase().contains(query)) {
gridPanel.add(createBookPanel(book));
}
}
gridPanel.revalidate();
gridPanel.repaint();
});
Sorting by Genre and A-Z
private JPanel createGenrePanel() {
JPanel genrePanel = new JPanel(new BorderLayout());

}
});
genreOptionsPanel.add(genreLabel);
}
genrePanel.add(genreOptionsPanel, BorderLayout.NORTH);
genrePanel.add(new JScrollPane(genreBooksPanel), BorderLayout.CENTER);
return genrePanel;
}
CRUD (Create, Read, Update, and Delete)
