Question

code: import java.awt.*; import java.applet.*; class HelloWorldApplet extends Applet{//an applet pu

关键是我的这个小applet 编译的正确吗？我是 在ubuntu 中编译 的，只是在javac时，将public 去掉了。

Answer 1

import java.applet.Applet;
import java.awt.Frame;
import java.awt.Graphics;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

public class Test extends Applet {

public static void main(String args[])
{

Test test=new Test();
test.init();
test.start();

Frame f=new Frame();

f.add(test);//只加了这一行

f.setSize(150,150);
f.setVisible(true);
f.addWindowListener(new WindowControl(test));

}
public void paint(Graphics g)
{

g.drawString("成功了",30,30);
}
public void destroy()
{
System.exit(0);
}
}
class WindowControl extends WindowAdapter
{
Applet c;
public WindowControl(Applet c)
{
this.c=c;
}
public void WindowControl(WindowEvent e)
{
c.destroy();
}

}
