Question

谁有J2ME源代码？

按住CTRL键能看源代码的那种。。。

import javax.microedition.lcdui.*;
import javax.microedition.lcdui.game.*;

public class ExampleGameCanvas extends GameCanvas implements Runnable{
private boolean isPlay;
private long delay;
private int currentX,currentY;
private int width;
private int height;

public ExampleGameCanvas(){
super(true);
width=getWidth();
height=getHeight();
currentX=width/2;
currentY=height/2;
delay=20;

}
public void start(){
isPlay=true;
Thread t=new Thread(this);
t.start();
}
public void stop(){isPlay=false;}

public void run(){
Graphics g=getGraphics();
while(isPlay==true){
input();
drawScreen(g);
try{Thread.sleep(delay);}
catch(Exception e){}
}
}

private void input(){
int keyStates=getKeyStates();
//左键
if((keyStates & LEFT_PRESSED)!=0)
currentX=Math.max(0,currentX-1);
//右键
if((keyStates & RIGHT_PRESSED)!=0)
if(currentX+5<width)
currentX=Math.min(width,currentX+1);
//上键
if((keyStates & UP_PRESSED)!=0)
currentY=Math.max(0,currentY-1);
if((keyStates & DOWN_PRESSED)!=0)
if(currentY+10<height)
currentY=Math.min(height,currentY+1);
}
//显示
private void drawScreen(Graphics g){
g.setColor(0xffffff);
g.fillRect(0,0,getWidth(),getHeight());
g.setColor(0x0000ff);
g.drawString("x",currentX,currentY,Graphics.TOP|Graphics.LEFT);
flushGraphics();
}
}

import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;

public class ExampleGameCanvasMidlet extends MIDlet {
private Display display;

public void startApp() {
display = Display.getDisplay(this);
ExampleGameCanvas gameCanvas = new ExampleGameCanvas();
gameCanvas.start();
display.setCurrent(gameCanvas);
}

public Display getDisplay() {
return display;
}

public void pauseApp() {
}

public void destroyApp(boolean unconditional) {
exit();
}

public void exit() {
System.gc();
destroyApp(false);
notifyDestroyed();
}
}

这是一个本人写的小游戏（初学者）

WTK下的演示程序有自带的源码，Sun官方的，绝对权威，要学会查找。。
