StringBuffer Problem

Hey guys. I have a program in which I get user input through a GUI, parse that input to a StringBuffer, then pass the StringBuffer over to another file, which then uses the input to run a program. I want the program to be run only if the user actually does put input in.

I thought I could do this with a simple if statement, such as:

if (FPTMchoicesBuffer !=null){

...

}

But this isn't working, the program just runs no matter what. Is there any other way for me to test if the StringBuffer was written to?

Like FPTMchoicesBuffer.toString().length != 0Also, user StringBuilder instead of StringBuffer

yes, if you have just initialize your StringBuffer (ed: StringBuffer mybuffer = new StringBuffer() ) it is not null !!Check the StringBuffer length or content with regExp.

if (FPTMchoicesBuffer.length() > 0) {... }

Thanks guys, it worked.Zadok, I read that I should use StringBuffer instead. Something about synchronization. Should I not?

Is the StringBuffer used by multiply threads?

Yes, use StringBuffer

No, Use StringBuilder, it is slightly faster.
