好吧，所以我有一个JList和内容提供了一个数组。我知道如何将元素添加到数组，但我想知道如何刷新JList ...或者甚至有可能吗？我试过谷歌。 ：\java刷新数组到jList

import java.applet.Applet;

import java.awt.*;

import javax.swing.*;

import java.awt.event.*;

public class bs extends JApplet implements MouseListener {

public static String newline;

public static JList list;

public void init() {

String[] data = {"one", "two", "three", "four"};

list = new JList(data);

this.getContentPane().add(list);

list.addMouseListener(this);

String newline = "\n";

list.setVisible(true);

}

public void refresh(){

Address found;

this.listModel.clear();

int numItems = this.getAddressBookSize();

String[] a = new String[numItems];

for (int i=0;i

found = (Address)Addresses.get(i);

a[i] = found.getName();

}

/* attempt to sort the array */

Arrays.sort(a, String.CASE_INSENSITIVE_ORDER);

for (int i=0;i

this.listModel.addElement(a[i]);

}

}

public void mousePressed(MouseEvent e) { }

public void mouseReleased(MouseEvent e) {

Object index = list.getSelectedValue();

System.out.println("You clicked on: " + index);

}

public void mouseEntered(MouseEvent e) { }

public void mouseExited(MouseEvent e) { }

public void mouseClicked(MouseEvent e) { }

public void paint(Graphics g) {

}

}

任何想法？

谢谢。
