关于java Swing的基本开发教程，以贪吃蛇游戏为实例，但本教程并不是0基础教程，需要有一定的java基础才可以明白。

这一讲三个类的源代码
snackMain类
package game;
import javax.swing.*;
public class snackMain extends JFrame{
public snackMain() {
  snackWin win = new snackWin();
  add(win);
  setTitle("贪吃蛇1.0v---七夕小雨作品");
  setSize(435,390);
  setLocation(200, 200);
  setVisible(true);
}
public static void main(String[] args) {
  new snackMain();
}
}

snckaWin类

package game;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.util.*;
import java.util.List;
public class snackWin extends JPanel implements ActionListener,KeyListener{
JButton newGame,stopGame;
int fenShu=0,Speed=0;
boolean start = false;
Random r = new Random();
int rx = 0,ry=0;
List<snackAct> list = new ArrayList<snackAct>();
public snackWin() {
  newGame = new JButton("开始");
  stopGame =new JButton("退出");
  this.setLayout(new FlowLayout(FlowLayout.LEFT));
  newGame.addActionListener(this);
  stopGame.addActionListener(this);
  this.addKeyListener(this);
  this.add(newGame);
  this.add(stopGame);
}
public void paintComponent(Graphics g){
  super.paintComponent(g);
  g.drawRect(10, 40, 400, 300);
  g.drawString("分数："+fenShu, 150, 20);
  g.drawString("速度："+Speed, 150, 35);
  g.setColor(new Color(0,255,0));
  if (start) {
g.fillRect(10+rx*10, 40+ry*10, 10, 10);
g.setColor(new Color(255,0,0));
for (int i = 0; i < list.size(); i++) {
g.fillRect(10+list.get(i).getX()*10, 40+list.get(i).getY()*10, 10, 10);
}
  }
}
public void actionPerformed(ActionEvent e) {
  if (e.getSource()==newGame) {
newGame.setEnabled(false);
start = true;
rx = r.nextInt(40);ry = r.nextInt(30);
snackAct tempAct = new snackAct();
tempAct.setX(20);
tempAct.setY(15);
list.add(tempAct);
requestFocus(true);
repaint();
  }
  if (e.getSource()==stopGame) {
System.exit(0);
  }
}
public void move(int x,int y){
  if (minYes(x, y)) {
list.get(0).setX(list.get(0).getX()+x);
list.get(0).setY(list.get(0).getY()+y);
repaint();
  }else {

  }
}
public boolean minYes(int x,int y){
  if (!maxYes(list.get(0).getX()+x, list.get(0).getY()+y)) {
return false;
  }
  return true;
}
public boolean maxYes(int x,int y){
  if (x<0||x>=40||y<0||y>=30) {
return false;
  }
  return true;
}
public void keyPressed(KeyEvent e) {
  if (start) {
switch (e.getKeyCode()) {
case KeyEvent.VK_UP:
move(0, -1);
break;
case KeyEvent.VK_DOWN:
move(0, 1);
break;
case KeyEvent.VK_LEFT:
move(-1, 0);
break;
case KeyEvent.VK_RIGHT:
move(1, 0);
break;
default:
break;
}
  }
}
public void keyReleased(KeyEvent arg0) {}
public void keyTyped(KeyEvent arg0) {}
}

snackAct类
package game;
public class snackAct {
private int x;
private int y;
public int getX() {
  return x;
}
public void setX(int x) {
  this.x = x;
}
public int getY() {
  return y;
}
public void setY(int y) {
  this.y = y;
}
}
