Trailing squares problem

Hi
I encountered a very low-level problem.
I found the string fetched from db.db maybe have some trailing blanks. the unicode of these characters is '\u0000' and they display trailing squares in the JTable. I had assumed that those characters could be removed by String.trim() but they turned out not to be whitespaces .
How you guys solved the situation? using a loop? it works but a little awkward i think
Any small tricks? :roll:
Regards.

use trim method on the data that u get
this will solve the problem

the trim() method could not do the work, it just remove the whitespaces
