{ 请尽量用准确的文字描述作为标题 }

我刚开始学习java遇到了一个问题谁能帮我解决？编译时总是出错令我迷茫 Sad

import java.awt.*;
import java.awt.event.*;
public class A extends Frame implements ActionListener
{ Button b1,b2;
FileDialog op;
FileDialog sv;
A()
{
setVisible(true);setSize(50,50);
b1=new Button("open");
b2=new Button("store");
add(b1);add(b2);pack();
op=new FileDialog(this,"open",FileDialog.LOAD);
sv=new FileDialog(this,"save",FileDialog.SAVE);
b1.addActionListener(this);
b2.addActionListener(this);
}
public void actionPerformed(ActionListener e)
{
if(e.getSource()==b1)
{op.setVisible(true);}
if(e.getSource()==b2)
{sv.setVisible(true);}
}
public static void main(String args[])
{A a=new A();}
}
