A WavePlayer class will be provided for playing a Wave InputStream, sample usage:

URL link;
link = new URL("http://humanum.arts.cuhk.edu.hk/Lexis/lexi-can/sound/ngo5.wav");
WavePlayer p = new WavePlayer( link.openStream() );
p.play();
________________________________________________
1.我唔係好明URL InputStream 同 openstream ();

2.我識過放上面呢4行code 入去但係唔work, 有d咩問題?

3.我依家有個textfield (under JFrame 既GUI)

如果我係textfield度打左d字

之後禁enter, 點樣將我打左既字變成string 同埋 點樣係禁enter之後perform action?

個class名係JTextField

String s = textField.getText();

listener:
http://docs.oracle.com/javase/tutorial/uiswing/events/intro.html

果4行code我得喎.....記住要放響main method

thx

Your Task:
1. Create a new NetBeans project named TextReader, with NO main class, but a new
JFrame Form called TextReader. Put it under a package named textreader.

2. Before you code, draw (drag-and-drop) your GUI design first under the New JFrame Form!

My current TextReader.java

/*
