NetBeans IDE (NetBeans) Application
GUI Form JFrame Component Control Layout Frame AWT (java.awt.Frame) Swing JFrame(javax.swing.JFrame) https://www.ntu.edu.sg/home/ehchua/programming/java/j4a_gui.html http://www2.hawaii.edu/~takebaya/ics111/inheritance/inheritance.html
javax.swing.JFrame packagecom.java.myapp; importjavax.swing.JFrame; publicclassMyClass { publicstaticvoidmain(String[] args) { JFrameframe = newJFrame("A JFrame"); frame.setSize(250, 250); frame.setLocation(300,200); frame.setVisible(true); } } https://www.thaicreate.com/java/java-gui-jframe.html
package& import package com.java.myapp; import javax.swing.JComponent; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JOptionPane; import javax.swing.JPasswordField; import javax.swing.JTextField; import java.awt.Font;
Create Form & Add Component // Create Form Frame super("ThaiCreate.Com Tutorial"); setSize(679, 385); setLocation(500, 280); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); getContentPane().setLayout(null); //Add Label Welcome lblWelcome = new JLabel("lblWelcome",JLabel.CENTER); lblWelcome.setFont(new Font("Tahoma", Font.PLAIN, 20)); lblWelcome.setBounds(168, 153, 336, 25); getContentPane().add(lblWelcome); // When Frame Event Loaded addWindowListener(new WindowAdapter() { @Override public void windowOpened(WindowEvent e) { LoginDialog(); } });
Object Get & Set text double water = Double.parseDouble(Input1.getText()); double elec = Double.parseDouble(Input2.getText()); double oil = Double.parseDouble(Input3.getText()); double rent = Double.parseDouble(Input4.getText()); double exp = Double.parseDouble(Input5.getText()); lblResult.setText(String.valueOf(water + elec+ oil + rent + exp)); http://javanetbeansgui.blogspot.com/2009/12/java-4.html
AWT Event Listeners java.util.EventListener ActionListener ComponentListener ItemListener KeyListener MouseListener TextListener WindowListener AdjustmentListener ContainerListener MouseMotionListener FocusListener https://www.nytimes.com/guides/smarterliving/be-a-better-listener
AwtListenerDemo.java import java.awt.event.*; okButton.addActionListener(new CustomActionListener()); class CustomActionListener implements ActionListener{ public void actionPerformed(ActionEvent e) { statusLabel.setText("Ok Button Clicked."); } }
JDBC API DataSourceobject Connection object Statement, PreparedStatement, and CallableStatementobjects ResultSetobject
Connecting Database Using JDBC public class JDBCUtil { String className, URL, user, password; Connection connection; public JDBCUtil(String className, String URL, String user, String password) { this.className = className; this.URL = URL; this.user = user; this.password = password; this.connection = null; } public void getConnection() { //Load the driver class try { Class.forName(className); } catch (ClassNotFoundException ex) { System.out.println("Unable to load the class. Terminating the program"); System.exit(-1); } //get the connection try { connection = DriverManager.getConnection(URL, user, password); } catch (SQLException ex) { System.out.println("Error getting connection: " + ex.getMessage()); System.exit(-1); } catch (Exception ex) { System.out.println("Error: " + ex.getMessage()); System.exit(-1); } } } https://www.progress.com/blogs/jdbc-tutorial-connecting-to-your-database-using-jdbc https://www.oracle.com/database/technologies/appdev/jdbc.html
Ex. Login Username Password Connection connect = null; PreparedStatementpre = null; Boolean status = false; Class.forName("com.mysql.jdbc.Driver"); connect = DriverManager.getConnection("jdbc:mysql://localhost/mydatabase?user=root&password=root"); String sql= " SELECT * FROM member WHERE Username = ? AND Password = ? "; pre = connect.prepareStatement(sql); pre.setString(1, userName); pre.setString(2, passWord); ResultSetrec = pre.executeQuery(); if(rec.next()) { lblWelcome.setText("Welcome : " + rec.getString("Name")); status = true; } https://www.thaicreate.com/java/java-gui-example-login-username-password.html
Database Metadata via JDBC Driver databaseMetaData = connection.getMetaData(); //Print TABLE_TYPE "TABLE" ResultSet resultSet = databaseMetaData.getTables(null, null, null, new String[]{ TABLE }); System.out.println("Printing TABLE_TYPE \"TABLE\" "); System.out.println("----------------------------------"); while(resultSet.next()) { //Print System.out.println(resultSet.getString("TABLE_NAME")); } https://www.progress.com/blogs/jdbc-tutorial-extracting-database-metadata-via-jdbc-driver http://tutorials.jenkov.com/jdbc/resultset.html
Table Info getTables(String catalog, String Schema, String tableNamepattern, string type)
Column Info getColumns(String Schema, String catalog, String tableNamePattern, String ColumnNamePattern)
