java新手提问

前些日子照深入浅出写了段小程序,结果编译出现类访问权限错误,请大侠帮帮忙,到底是哪里出了问题.

程序如下:

import java.awt.*;
import java.applet.*;

public class Graphics_new extends Applet{
public void paint(Graphics g){
Font f = new Font("SanSerif",Font.PLAIN,10);
g.setFont(f);
FontMetrics fm = g.getFontMetrics(f);
int h = fm.getHeight();
int cx = 200;
int cy = 100;
int cx0 = 0;
int cy0 = 0;
int nLineT = 3;
setBackground(Color.lightGray);
g.drawString("(0,0)",2 * nLineT,h);
g.fillRect(cx0,cy0,cx,nLineT);
g.drawString("(200,0)",cx,h);
g.fillRect(cx0,cy0,nLineT,cy);
g.drawString("(0,100)",2*nLineT,cy);
}
public void init(){
setSize(300,130);
}
}


编译错误:
init:

deps-jar:

eclipse下没有问题

[luxin24]

我用的是NetBeans5

[sundingpan]

在命令提示符下编译没问题

我用的是NetBeans5.5beta, 也没问题。
