初学，见笑了。
为什么这段程序会在运行时出错？
import javax.microedition.lcdui.Canvas;
import javax.microedition.lcdui.Display;
import javax.microedition.lcdui.Graphics;
import javax.microedition.midlet.MIDlet;
import javax.microedition.midlet.MIDletStateChangeException;

public class Paint extends MIDlet {

private Display display;
private boolean started;

public Paint() {
// TODO Auto-generated constructor stub
started = false;
}

protected void destroyApp(boolean arg0) throws MIDletStateChangeException {
// TODO Auto-generated method stub

}

protected void pauseApp() {
// TODO Auto-generated method stub

}

protected void startApp() throws MIDletStateChangeException {
// TODO Auto-generated method stub
if (!started) {
display = Display.getDisplay(this);
display.setCurrent(new MyCanvas());
}

}

class MyCanvas extends Canvas {

public MyCanvas() {
}

protected void paint(Graphics g) {
g.fillRect(0, 0, this.getWidth(), this.getHeight());
g.drawString("Here", 0, 0, Graphics.TOP);
}

}

}

不知道是不是在paint（）的时候

第四个参数anchor写的有问题呢。
g.drawString("Here", 0, 0, Graphics.TOP); //这个坐标(0，0)只确定了顶部TOP，不知道是在LEFT还是RIGHT
