Hi,
I'm trying to clear out the contents of a string buffer in Java 1.1, can anybody supply the necessary code.
I know 1.2 provides replace and delete methods but they are not available to me in 1.1

Any ideas out there ?

use StringBuffer.setLength(int len), and set len to zero....

StringBuffer sb = new StringBuffer();
sb.append("Hello");            
sb.setLength(0);
// sb is now empty...

Hope that this helps...

Hi Azawazi,
I'm using Visual J++ 1.1 and it doesn't work in that !
Very frustrating.

Hello again,
The setlenght(0) should work but for whatever reason it isn't in my development environment. I guess the lesson I've learnt is to upgrade my envoronment !

Recreate the instance of StringBUffer
i.e.

StringBuffer buf=new StringBuffer();
buf.append("TEST");
buf=new StringBuffer();
