我是新手  为什么我运行BorderLayout.java
可以运行
但是运行 FlowLayout.java  就说文件中不包含类FlowLyout ?

我加载的是  java.awt.*;
                   java.awt.evnet.*;
                   javax.swing.*;

是不是运行FlowLayout.java  需要加载别的包？

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class  FlowLayoutDemo
{
    public FlowLayoutDemo()
    {
        JFrame f = new JFrame();
        Container  contentPane = f.getContentPane();
        contentPane.setLayout(new FlowLayout());
        contentPane.add(new JButton("first"));
        contentPane.add(new JButton("second"));
        contentPane.add(new JButton("third"));
        contentPane.add(new JButton("fourth"));
        contentPane.add(new JButton("fifth"));
        contentPane.add(new JButton("This is the last button"));
        f.setTitle("FlowLayout");
        f.setSize(getPreferredSize());
        f.setVisible(true);
        f.addWindowListener(new WindowAdapter()
        {
            public void windowClosing(WindowEvnet e)
            {System.exie(0);}
        });
    }
    public Dimension getPreferredSize()
    {
        return new Dimension(200,200);
    }
    public static void main(String [] args)
    {
        FlowLayoutDemo b = new FlowLayoutDemo();
    }
}
