重寫paint方法，來實(shí)現(xiàn)將自己定義的圖片繪制到組件中，然后啟動(dòng)一個(gè)線程來控制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("人物行走圖");new Thread(p).start();this.setVisible(true);this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);}public static void main(String args[]){new test();} }××××××××××××××××××××××× 將以上源碼保存為：test.java，編譯，然后下載下面的圖片 將下載的圖片改名為1.png" target="_blank"

java在JFrame上畫東西，主要是使用paint方法，代碼如下：
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();//添加畫圖，把上面jpanel的設(shè)置給覆蓋了；要是先添加畫圖再添加
add(drawaction);????????????????????//jpanel則把畫圖覆蓋了
}
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);
}
}

public?void?paintComponent(Graphics?g){
super.paintComponents(g);
g.drawString("agagh",?50,?45);
}
}
運(yùn)行結(jié)果如下：
