爱心拯救Blogger王俊

几年前，当一部《死亡日记》问世的时候，人们都在感叹作者的坦然和生命的脆弱。最近几天不断看到关于befresh（王俊）的事情，再次感觉到，原来生命是这样的不堪一击。今天，很认真地看了一下他的blog，名字叫寸心知，文章千古事，得失寸心知，看到这两句话心里酸酸的，最后更新时间在2月份，不禁为这么好的程序员、这么好的blogger感到惋惜。

从经济上来支援对我来说似乎有点力不从心，所以只能在这里真诚的呼唤、号召大家伸出你们的援助之手。

The Swing event model

1.Event and listener types

Event, listener interface and add- and remove-methods	Components supporting this event
ActionEvent ActionListener addActionListener( ) removeActionListener( )	JButton, JList, JTextField, JMenuItem and its derivatives including JCheckBoxMenuItem, JMenu, and JpopupMenu.
AdjustmentEvent AdjustmentListener addAdjustmentListener( ) removeAdjustmentListener( )	JScrollbar and anything you create that implements the Adjustable interface.
ComponentEvent ComponentListener addComponentListener( ) removeComponentListener( )	*Component and its derivatives, including JButton, JCanvas, JCheckBox, JComboBox, Container, JPanel, JApplet, JScrollPane, Window, JDialog, JFileDialog, JFrame, JLabel, JList, JScrollbar, JTextArea, and JTextField.
ContainerEvent ContainerListener addContainerListener( ) removeContainerListener( )	Container and its derivatives, including JPanel, JApplet, JScrollPane, Window, JDialog, JFileDialog, and JFrame.
FocusEvent FocusListener addFocusListener( ) removeFocusListener( )	Component and derivatives*.
KeyEvent KeyListener addKeyListener( ) removeKeyListener( )	Component and derivatives*.
MouseEvent (for both clicks and motion) MouseListener addMouseListener( ) removeMouseListener( )	Component and derivatives*.
MouseEvent[68] (for both clicks and motion) MouseMotionListener addMouseMotionListener( ) removeMouseMotionListener( )	Component and derivatives*.
WindowEvent WindowListener addWindowListener( ) removeWindowListener( )	Window and its derivatives, including JDialog, JFileDialog, and JFrame.
ItemEvent ItemListener addItemListener( ) removeItemListener( )	JCheckBox, JCheckBoxMenuItem, JComboBox, JList, and anything that implements the ItemSelectable interface.
TextEvent TextListener addTextListener( ) removeTextListener( )	Anything derived from JTextComponent, including JTextArea and JTextField.

3. Display the "addXXXListener" methods of any  Swing class.

//: c13:ShowAddListeners.java // Display the "addXXXListener" methods of any // Swing class. // <applet code = ShowAddListeners // width=500 height=400></applet> import javax.swing.*; import javax.swing.event.*; import java.awt.*; import java.awt.event.*; import java.lang.reflect.*; import java.io.*; import com.bruceeckel.swing.*; import com.bruceeckel.util.*; public class ShowAddListeners extends JApplet { Class cl; Method[] m; Constructor[] ctor; String[] n = new String[0]; JTextField name = new JTextField(25); JTextArea results = new JTextArea(40, 65); class NameL implements ActionListener { public void actionPerformed(ActionEvent e) { String nm = name.getText().trim(); if(nm.length() == 0) { results.setText("No match"); n = new String[0]; return; } try { cl = Class.forName("javax.swing." + nm); } catch(ClassNotFoundException ex) { results.setText("No match"); return; } m = cl.getMethods(); // Convert to an array of Strings: n = new String[m.length]; for(int i = 0; i < m.length; i++) n[i] = m[i].toString(); reDisplay(); } } void reDisplay() { // Create the result set: String[] rs = new String[n.length]; int j = 0; for (int i = 0; i < n.length; i++) if(n[i].indexOf("add") != -1 && n[i].indexOf("Listener") != -1) rs[j++] = n[i].substring(n[i].indexOf("add")); results.setText(""); for (int i = 0; i < j; i++) results.append( StripQualifiers.strip(rs[i]) + "\n"); } public void init() { name.addActionListener(new NameL()); JPanel top = new JPanel(); top.add(new JLabel( "Swing class name (press ENTER):")); top.add(name); Container cp = getContentPane(); cp.add(BorderLayout.NORTH, top); cp.add(new JScrollPane(results)); } public static void main(String[] args) { Console.run(new ShowAddListeners(), 500,400); } } ///:~

Java 笔记 之 Applet 若干技巧

发表于 @ 2005年01月15日 9:20 PM | 评论 (1)

TIJ 笔记 之 class不为每个reference产生缺省对象

class不为每个reference产生缺省对象，但是对基本数据类型则默认初始化为0

//: c06:SprinklerSystem.java // From 'Thinking in Java, 2nd ed.' by Bruce Eckel // www.BruceEckel.com. See copyright notice in CopyRight.txt. // Composition for code reuse. class WaterSource { private String s; WaterSource() { System.out.println("WaterSource()"); s = new String("Constructed"); } public String toString() { return s; } } public class SprinklerSystem { private String valve1, valve2, valve3, valve4; WaterSource source; int i; float f; void print() { System.out.println("valve1 = " + valve1); System.out.println("valve2 = " + valve2); System.out.println("valve3 = " + valve3); System.out.println("valve4 = " + valve4); System.out.println("i = " + i); System.out.println("f = " + f); System.out.println("source = " + source); } public static void main(String[] args) { SprinklerSystem x = new SprinklerSystem(); x.print(); } } ///:~

输出结果为：

---------- java ----------
valve1 = null
valve2 = null
valve3 = null
valve4 = null
i = 0
f = 0.0
source = null

输出完成 (耗时 0 秒) - 正常终止

Java 笔记之 关于 Java 中的初始化 及顺序

tij 中的代码，仔细研究一下

运行结果：

---------- java ----------

Bowl(4)
Bowl(5)
Bowl(3)
Cupboard()
f(2)
Creating new Cupboard() in main
Bowl(3)
Cupboard()
f(2)
Creating new Cupboard() in main
