application/x-www-form-urlencoded MIME format. For more information about HTML form encoding, consult the HTML
specification.
When encoding a String, the following rules apply:
a" through "z", "A" through "Z" and "0" through "9" remain the same.
.", "-", "*", and "_" remain the same.
" is converted into a plus sign "+".
%xy", where
xy is the two-digit hexadecimal representation of the byte. The recommended encoding scheme to use is UTF-8. However, for compatibility reasons, if an encoding is not specified, then the default encoding of the platform is used.
For example using UTF-8 as the encoding scheme the string "The string ü@foo-bar" would get converted to "The+string+%C3%BC%40foo-bar" because in UTF-8 the character ü is encoded as two bytes C3 (hex) and BC (hex), and the character @ is encoded as one byte 40 (hex).
| Modifier and Type | Method and Description |
|---|---|

encode(String s)
Deprecated.
The resulting string may vary depending on the platform‘s default encoding. Instead, use the encode(String,String) method to specify the encoding.

encode(String s,
String enc)
Translates a string into
application/x-www-form-urlencoded format using a specific encoding scheme. |
clone, equals, finalize,
getClass, hashCode, notify, notifyAll, toString,
wait, wait, wait//解释一下：这是jdk1.7里面的官方说明。大致的意思是，URLEncode是将字符串转换为application/x-www-form-urlencoded MIME格式。例子：The string ü@foo-bar用utf-8编码为The+string+%C3%BC%40foo-bar
有两个方法：encode（String s）和encode（String s，String encode）
encode（String s）用平台默认的编码方式进行编码，谨慎使用！
encode（String s，String enc）用指定的编码方式进行编码，最好使用此方式，指定编码格式，以免随着环境的变幻而产生中文乱码
