Cleanup StringBuffer

[Angela Jessi]

Hi,
How can I cleanup the buffer(if somebody can explain me with syntax)?
Thanks in advance,
Angela

I believe stringBuffer.setLength(0); should do your job.

"Dean J",
The Java Ranch has thousands of visitors every week, many with surprisingly similar names. To avoid confusion we have a naming convention, described at http://www.javaranch.com/name.jsp . We require names to have at least two words, separated by a space, and strongly recommend that you use your full real name. Please choose a new name which meets the requirements.
Thanks.

Thanks Dean,
Is stringbuffer.setLength(0) method clears the buffer ?
Plz let me know,
Thanks in advance,
Angela

Hello,
The setLength method of stringbuffer when used with an int constructor will set the length of the buffer to whatever the integer argument is. Using zero will essentially set the length to zero, effectively clearing the buffer. For more info on String buffer see...

Thanks Pat,
Also String buffer append method will start appending at starting point in the memory while other application running in the memory?
Thanks,
Angela

Angela can you explain your question ?

Thanks Siva,
We have Global Heap memory where java application runs. while java application is running, it allocates some memory in global heap. Now if I have allocated memory for String Buffer, and when I used append method to insert some data, it will start appending at starting point in Global Heap Memory or it will append the data to applications which is running.
Plz let me know for further clarification,
Thanks again Siva,

The delete(start,end) method would also work:
buffer.delete(0,buffer.length()-1);
Enjoy!

In answer to the "Heap" posting ... one of the nice things about Java is that you don't have to care (for the most part) about your memory management. The internals do all that for you. The code that I just posted is all that you have to do ... any memory reallocation is done by the JVM.
