这个好玩不好玩：JLabel theText = new JLabel( "<html>Hello! This is a multiline label with <b>bold</b> " + "and <i>italic</i> text. <P> " + "It can use paragraphs, horizontal lines, <hr> " + "<font color=red>colors</font> " + "and most of the other basic features of HTML 3.2</html>");
其实 grantdyg已经给出了很好的代码，我的与他差不多，那天只是要下班了不想写了。给你吧，差不多一样的，不用document： jEditorPane1.setContentType("text/html"); jEditorPane1.setText("<html>Hello! This is a multiline label with <b>bold</b> " + "and <i>italic</i> text. <P> " + "It can use paragraphs, horizontal lines, <hr> " + "<font color=red>colors</font> " + "and most of the other basic features of HTML 3.2</html>"); 这种方法有一个问题，如果用于聊天室的构造。你看出来的吧。
cannot auto refresh? i dont know. 有请 sharetop(天生不笨) 提示一下，分就到手了。
可以用JEditPanel类来处理，不过如果你要稍做处理，否则它只显示一个URL。你可以用Document来做中间处理，下周来我给你代码吧。或是你详细看一下API文档，会有发现的。

grantdyg(正确) 的回答很好，感谢。会得分的。请教别的swing控件中有没有能显示html的。
热切等待 sharetop(天生不笨) 的代码。
JEditPane可以显示html，而且可以编辑
其实 grantdyg已经给出了很好的代码，我的与他差不多，那天只是要下班了不想写了。给你吧，差不多一样的，不用document： jEditorPane1.setContentType("text/html");
jEditorPane1.setText("<html>Hello! This is a multiline label with <b>bold</b> "
+ "and <i>italic</i> text. <P> "
+ "It can use paragraphs, horizontal lines, <hr> "
+ "<font color=red>colors</font> "
+ "and most of the other basic features of HTML 3.2</html>");
这种方法有一个问题，如果用于聊天室的构造。你看出来的吧。
有请 sharetop(天生不笨) 提示一下，分就到手了。
或者：
jEditorPane1.validate()
