5.3.9 Implementasi Kelas HalamanTampilTabel

Berikut merupakan implementasi dari atribut dan method pada kelas HalamanTampilTabel.java yang dibuat sesuai dengan perancangannya. Kelas ini memiliki method tampilTabel dan pilihTabel yang berkaitan dengan fungsi input data dari tabel basisdata karena bertindak sebagai interface untuk menampilkan daftar tabel yang terdapat pada basisdata yang dipilih pengguna. public class HalamanTampilTabel extends javax.swing.JFrame { DatabaseConnection conn; public HalamanTampilTabelDatabaseConnection conn, String database { initComponents; setResizablefalse; tampilTabelconn, database; } public void tampilTabelDatabaseConnection conn, String database { this.conn = conn; try { DatabaseController controller = new DatabaseController; ResultSet rs; if database.equalsOracle { rs = controller.tampilTableOracleconn.getConnection; while rs.next { daftarTableComboBox.addItemrs.getString1; } } else if database.equalsMySQL { rs = controller.tampilTableMySqlconn.getConnection; while rs.next { daftarTableComboBox.addItemrs.getString1; } } } catch SQLException ex { Logger.getLoggerHalamanTampilTabel.class.getName.logLevel.SEVE RE, null, ex; } } public void pilihTabel { java.awt.Window window[] = java.awt.Window.getWindows; for int i = 0; i window.length; i++ { window[i].dispose; window[i] = null; } HalamanUtama coba = new HalamanUtamaconn, daftarTableComboBox.getSelectedItem.toString; coba.setVisibletrue; jDesktopPane1.getMaximumSize; setExtendedStateMAXIMIZED_BOTH; } private void pilihTabelButtonActionPerformedjava.awt.event.ActionEvent evt { TODO add your handling code here: pilihTabel; } private void batalButtonActionPerformedjava.awt.event.ActionEvent evt { TODO add your handling code here: java.awt.Window window[] = java.awt.Window.getWindows; for int i = 0; i window.length; i++ { window[i].dispose; window[i] = null; } HalamanUtama utama = new HalamanUtama; utama.setVisibletrue; jDesktopPane1.getMaximumSize; setExtendedStateMAXIMIZED_BOTH; } Variables declaration - do not modify private javax.swing.JButton batalButton; private javax.swing.JLabel daftarLabel; private javax.swing.JComboBox daftarTableComboBox; private javax.swing.JDesktopPane jDesktopPane1; private javax.swing.JPanel jPanel1;
