<span style="font-size:18px;">import java.awt.*;
import java.awt.event.*;
import java.io.*;
class MyWindows 
{
	private Frame f;
	private TextField tf;
	private Button b ;
	private TextArea ta;
	
	MyWindows()
	{
		init();
	}
	private void init()
	{
		f = new Frame("我的視窗");
		f.setBounds(300,100,600,500);
		f.setLayout(new FlowLayout());

		tf = new TextField(50);
		b = new Button("轉到");
		ta = new TextArea(25,70);

		f.add(tf);
		f.add(b);
		f.add(ta);

		myEvent();
		f.setVisible(true);
	}
	
	private void myEvent()
	{
			 
		b.addActionListener(new ActionListener()
		{
			public void actionPerformed(ActionEvent e)
			{
				String dirPath = tf.getText();
				File dir = new File(dirPath);
				if (dir.exists() && dir.isDirectory())
				{
					ta.setText("");
					String[] names = dir.list();
					for(String name : names)
					{
						ta.append(name+"\r\n");
					}
				}
			}
		});
		f.addWindowListener(new WindowAdapter()
		{
			  public void windowClosing(WindowEvent e)
			{
				System.exit(0);
			}
		});
	}
	public static void main(String[] args) 
	{
		new MyWindows();
	}
