用eclipse编写的小程序，但是运行后，提示未初始化？怎么个情况，请高手指点。。。

代码：
import java.applet.*;
import java.awt.*;
import javax.swing.JApplet;
public class myclass extends JApplet{
public void paint(Graphics g){
Graphics2D g2=(Graphics2D)g;
int red,green,blue;
red=255;blue=255;green=0;
g2.setPaint( new Color(red,green,blue));
setBackground(Color.cyan);
g2.drawString("wellcom to xi/047an",25,75);
showStatus("Current RGB:"+g2.getPaint().toString());
}
}
