jdk.net.URLEncoder
Utility class for HTML form encoding. This class contains static methods for converting a String to the 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:
The alphanumeric characters a through
z, A through
Z and 0
through 9 remain the same.
The special characters .,
-, *, and
_ remain the same.
The space character is
converted into a plus sign +.
All other characters are unsafe and are first converted into
one or more bytes using some encoding scheme. Then each byte is
represented by the 3-character string
%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).

(*encode s)(*encode s enc)Translates a string into application/x-www-form-urlencoded format using a specific encoding scheme. This method uses the supplied encoding scheme to obtain the bytes for unsafe characters.
Note: The World Wide Web Consortium Recommendation states that UTF-8 should be used. Not doing so may introduce incompatibilities.
