how to convert special character registered trademark ® to number code & # 174;

[chaohua wang]

Hi Folks,

I need to convert special character ® to number code &# 174;

http://www.webmonkey.com/2010/02/special_characters/

is there any java API method which can do convert?
Thank you
Chwang

you mean like this?

javax.swing.JOptionPane.showMessageDialog(null, "\u00ae");

Or an HTML escaping utility, but I don't know if it would escape it to a named entity or the number. Apache Commons Lang has such utilities.

(And no, I don't think displaying it in an option pane is really converting it to an entity.)

The 174 is the int representation of the character; 00ae is hexadecimal for 174. So just cast your char into an int, then wrap it in &# and ;
