非常好，绝对的能用哦 !一下是一小部分代码 package gui; import java.awt.*; import java.applet.*; import java.awt.event.*; import javax.swing.*; //Download by http://www.codefans.net public class Fireworks extends Applet implements MouseListener,Runnable { int x,y; int top,point; /** *对小程序进行变量和颜色的初始化。 */ public void init() { x = 0; y = 0; //设置背景色为黑色 setBackground(Color.black); addMouseListener(this); } public void paint(Graphics g) { } /** *使该程序可以作为应用程序运行。 */ public static void main(String args[]) { Fireworks applet = new Fireworks(); JFrame frame = new JFrame("TextAreaNew"); frame.addWindowListener(new WindowAdapter() { public void windowClosing(WindowEvent e){ System.exit(0); } }); frame.getContentPane().add( applet, BorderLayout.CENTER); frame.setSize(800,400); applet.init(); applet.start(); frame.setVisible(true); } /** *程序主线程，对一个烟花进行绘制。 */ public void run() { //变量初始化 Graphics g1; g1 = getGraphics(); int y_move,y_click,x_click; int v; x_click = x; y_click = y; y_move = 400; v = 3; int r,g,b; while(y_move > y_click) { g1.setColor(Color.black); g1.fillOval(x_click,y_move,5,5); y_move -= 5; r = (((int)Math.round(Math.random()*4321))%200)+55; g = (((int)Math.round(Math.random()*4321))%200)+55; b = (((int)Math.round(Math.random()*4321))%200)+55; g1.setColor(new Color(r,g,b)); g1.fillOval(x_click,y_move,5,5); for(int j = 0 ;j<=10;j++) { if(r>55) r -= 20; if(g>55) g -= 20; if(b>55) b -=20; g1.setColor(new Color(r,g,b)); g1.fillOval(x_click,y_move+j*5,5,5); } g1.setColor(Color.black); g1.fillOval(x_click,y_move+5*10,5,5); try { Thread.currentThread().sleep(v++); } catch (InterruptedException e) {} } for(int j=12;j>=0;j--) { g1.setColor(Color.black); g1.fillOval(x_click,y_move+(j*5),5,5); try { Thread.currentThread().sleep((v++)/3); } catch (InterruptedException e) {} } y_move = 400; g1.setColor(Color.black); while(y_move > y_click) { g1.fillOval(x_click-2,y_move,9,5); y_move -= 5; }
