Unfortunately, I have checked the program options carefully, again and again, but didn't find how to change the user interface language. OK, have to go a bit search and reading.
In NetBeans FAQ, What are the NetBeans startup parameters (a.k.a command-line options), it tells
--locale language[:country[:variant]] : Use the specified locale.and, no more. I am not sure about the language [:country[:variant]], so searched again. Finally I came across a blog to find out the approaches.
Open the properties window of NetBeans shortcut, add the following read part at the end of the target, for example:
- "D:\Program Files\NetBeans 6.5 RC2\bin\netbeans.exe" --locale en:US.
This is for English. Replace the red part by --locale zh:CN for Chinese and --locale ja:JP for Japanese.
Moreover, I found some information on language [:country[:variant]], please go to http://java.sun.com/j2se/1.4.2/docs/api/java/util/Locale.html and http://java.sun.com/developer/technicalArticles/J2SE/locale/.
