怎么用java做动画
重写paint方法，来实现将自己定义的图片绘制到组件中，然后启动一个线程来控制paint方法。 示例： ××××××××××××××××××××××××××× import javax.swing.*; import java.awt.*;class MyPanel extends JPanel implements Runnable {private Image img;private int i=0;private int j=0;public MyPanel(){img=new ImageIcon("1.png").getImage();}public void paint(Graphics g){g.drawImage(img,0,0,60,104,i*60,j*104,i*60+60,j*104+104,this);}public void run(){while(true){while(j {while(i {try{Thread.sleep(300);}catch(Exception e){}this.repaint();i++;}j++;i=0;}i=0;j=0;}} }public class test extends JFrame {private MyPanel p;public test(){p=new MyPanel();this.add(p,BorderLayout.CENTER);this.setBounds(300,200,300,300);this.setTitle("人物行走图");new Thread(p).start();this.setVisible(true);this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);}public static void main(String args[]){new test();} }××××××××××××××××××××××× 将以上源码保存为：test.java，编译，然后下载下面的图片 将下载的图片改名为1.png" target="_blank"

,然后将其和编译后生成的class文件放在同一文件夹下，然后运行就可以了·～～
java究竟怎么在JFrame上画东西？
java在JFrame上画东西，主要是使用paint方法，代码如下：
import java.awt.Color;
import java.awt.Graphics;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class Draw extends JFrame{
JPanel jPanel=new JPanel();
public Draw() {
jPanel.setBackground(Color.red);
add(jPanel);
Drawation drawaction=new Drawation();//添加画图，把上面jpanel的设置给覆盖了；要是先添加画图再添加
add(drawaction); //jpanel则把画图覆盖了
}
public static void main(String[] args){
Draw draw=new Draw();
draw.setTitle("abc");
draw.setSize(300,300);
draw.setVisible(true);
draw.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}
class Drawation extends JPanel{
public void paintComponent(Graphics g){
super.paintComponents(g);
g.drawString("agagh", 50, 45);
}
}
运行结果如下：
