swing实现自动完成(智能匹配)功能--紫枫凝潇烟

近日完成了一个较复杂的JTree结构,并提供搜索功能，想着在搜索时再加个智能匹配的功能应该能提高用户体验，于是先完成了这个示例 ，效果就不贴图了，就是类似google的suggest那样的智能匹配功能，代码如下

 

package  swingdemo;

import  java.awt.BorderLayout;
import  java.awt.Container;
import  java.awt.Dimension;
import  java.awt.event.ActionEvent;
import  java.awt.event.ActionListener;
import  java.awt.event.KeyAdapter;
import  java.awt.event.KeyEvent;
import  java.awt.event.MouseAdapter;
import  java.awt.event.MouseEvent;
import  java.util.HashSet;
import  java.util.Set;

import  javax.swing.DefaultListModel;
import  javax.swing.JButton;
import  javax.swing.JComponent;
import  javax.swing.JFrame;
import  javax.swing.JList;
import  javax.swing.JPanel;
import  javax.swing.JPopupMenu;
import  javax.swing.JScrollPane;
import  javax.swing.JTable;
import  javax.swing.JTextField;
import  javax.swing.KeyStroke;
import  javax.swing.ListSelectionModel;


public   class  IntelligentMatch  extends  JFrame ... {


    private JTextField keywordField;

    private JPopupMenu popupMenu;
    private JList cacheKeywordList;
    private Set<String> cacheKeyword = new HashSet<String>();
    private Set<String> matchResultSet = new HashSet<String>();
    private ResultListModel resultListModel;
    private ListListener listListener = new ListListener();
    
    public IntelligentMatch()...{
        super();
        init();
        
    }
    
    public void
