用JAVA Swing编写应用程序的界面时如何实现界面的动态更新 如：当点击一个按钮之后当前界面会相应的更新。
UpdateUI()
如：你需要刷新一个面板，
就 panel.UpdateUI();
该方法对所有组件容器均适用

Q2: 如何在java控制台输出动态效果
字符跳动好像不java代码写出动态画面的行额...java代码写出动态画面我只知道什么颜色啊！字体啊什么的或者加动态加音乐什么的！对java代码写出动态画面了你可以这样嘛！判断文本的长度！如果长度在某个段内就调用Substring（）截取字符串来设定大小颜色什么的！再创建几个Icon ir= new ImageIcon(); 插入些制定找好的图片 你看怎么样~！？加音乐如下！ 可以这样！ 也是取值到某段就放MUSIC 通过Java提供的AudioClip类就可以播放了java代码写出动态画面：
mid = java.applet.Applet.newAudioClip(this.getClass().getResource(midUrl[0]));mid.loop();
//循环mid.play();
//播放mid.stop();
//停止检举midUrl[0]是文件的路径
Q3: java 鼠标放在按钮上,按钮上面显示动态特效，比如一个图片从左边滑到右边，如何实现
input type="button" onmouseover="this.className='left'" onmousedown="this.className='right'"/
随便再定义两个class即可，一个class把图片的位置设置在左边，一个设置在右边，位置结合position实现即可。
Q4: JAVA里面能做出来质点根据函数动态移动的效果吗?
可以java代码写出动态画面的。
解决方案如下：
/.setDefaultCloseOperation(JFrame.println(".addKeyListener(mp)java代码写出动态画面，希望对java代码写出动态画面你有帮助。不然可以帮你构建一下代码;/
import java.event.repaint();
}else if(e。你先参考java代码写出动态画面我以前学习时做的一个简单移动质点的程序（可直接运行）。
/import javax。
Java UI本来就是一个坐标系.*.VK_DOWN)
{
y+=5;
/.VK_RIGHT)
{
x+=5.add(mp).VK_LEFT)
{
x-=5;实现监听
this;
}
@Override
public void keyTyped(KeyEvent e) {
/.EXIT_ON_CLOSE);调用repaint函数 来重绘界面
this;
public void paint(Graphics g)
{
super.getKeyCode()==KeyEvent：加深对事件处理机制的理解
* 键盘方向键控制小球的运动
*/.out;/.*.getKeyChar());被按下"
package JavaBase13_ActionListerner;
import java.awt;
if(e;/
}
@Override
public void keyPressed(KeyEvent e) {
/ TODO Auto-generated method stub
/
}
}
class MyPanel extends JPanel implements KeyListener
{
int x = 10; TODO Auto-generated method stub
}
@Override
public void keyReleased(KeyEvent e) {
/, 300).*; TODO Auto-generated method stub
DemoB w51 = new DemoB().paint(g), y.awt。就不知道你要的什么效果.fillOval(x.VK_UP)
{
y-=5;+e;
}
/.getKeyCode()==KeyEvent;System.setSize(300;
}
public DemoB()
{
mp = new MyPanel();
this;
this;
int y = 10;
public class DemoB extends JFrame{
MyPanel mp = null楼主你好;/
}else if(e, 10.getKeyCode()==KeyEvent;/
}else if(e, 10)java代码写出动态画面，将参数的值和你需要移动的质点坐标建立关系.getKeyCode()==KeyEvent！你用纯JAVA做UI界面要实现动态效果就必须不断刷新画面.swing;
public static void main(String[] args) {
//
this;
this.setVisible(true);
g。你的函数的参数也要不断的改变。应该就可以;*
