java烟花程序看不懂，求解释！import java.awt.*;
import java.applet.*;
import java.awt.event.*;
import javax.swing.*;
public class Fireworks extends Applet implements MouseListener, Runnable {
int x, y;//记录鼠标点击的坐标
int top, point;//好像没用到
public void init() {
x = 0;
y = 0;
setBackground(Color.black);// 设置背景色为黑色
addMouseListener(this);//添加鼠标监听
}
public void paint(Graphics g) {
}
public static void main(String args[]) {
Fireworks applet = new Fireworks();
JFrame frame = new JFrame("TextAreaNew");
frame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {//右上角的叉
System.exit(0);
}
});
frame.add(applet, BorderLayout.CENTER);
frame.setSize(800, 400);//程序的框框大小
applet.init();
applet.start();
frame.setVisible(true);//
}
public void run() {
// 变量初始化
Graphics g1;
g1 = getGraphics();//这是画笔，得到一个画笔
int y_move, y_click, x_click;
int v;//用于计算等待的时间
x_click = x;
y_click = y;//把点击的坐标保存下来，因为其它线程会去改这两个坐标 。
