How to convert a sequence of character to UTF-8 in Java?
Question
Sorry for asking basic questions here. Pardon me.
I have a sequence a string in this in unicode as follows.
String unicode = "\u8BF7\u5728\u6B64\u5904\u8F93\u5165\u4EA7\u54C1\u7F16\u53F7\u6216\u540D\u79F0";
How can I convert this to Chinese text or the UTF-8 text ?

The String itself will always be in Unicode; I'm not sure what you mean by "convert this to Chinese text" but to convert it to the binary representation using UTF-8 you'd use:
byte[] bytes = unicode.getBytes("UTF-8");
or you can use the Charset - using the Guava library for example, you'd just use:
byte[] bytes = unicode.getBytes(Charsets.UTF_8);
(This gets round the brittleness of specifying a string, and avoids worrying about catching UnsupportedEncodingException .)
Or you can declare:
final static Charset UTF_8 = Charset.forName("UTF-8");
at the top of your class to avoid a whole library as a cure for the string.

您在上面说过要输出到浏览器吗？...如果您使用的是servlet或类似的方法，则可以采用多种方法，因此您可能需要在问题中更具体一些，因为可以指定unicode / utf http响应标头或html输出中的-8 / utf-16，例如，在<head>元素内部输出以下标记：
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
