What values?

To empty a StringBuffer, use setLength(0) on it.

Or do you mean something else?

Re: StringBuffer Question

I would like to know
how to empty out a strring buffer.

i am developing an application that uses serial com communication
that receives infor from the port. i write the data into a stringbuffer.
when new info is received at the port i read it into the stringbuffer
but the previous data is still in the stringbuffer. ia don't what the
previous info
there.

I have tried both the above mentioned scenarios adn they didnt
help

StringBuffer sb("ABCDE");

// 1) Empty buffer using 'delete'
sb.delete(0, sb.length());

// or:

// 2) Empty buffer using 'replace'
sb.replace(0, sb.length(), "");

// or:

// 3) Empty buffer using 'setLength'
sb.setLength(0) ;

All three of these approaches have the effect of 'emptying' the StringBuffer
object of its contents [of characters] but do not alter its capacity, the
currently-available storage for additional characters.

Your problem is likely to have other causes. Perhaps if you posted the
relevant piece of source code constructive suggestions could be made.

I hope this helps.
