Empty StringBuffer in java

[TechGate]

Hello,
Is there a clean and efficient way to clear an instance of StringBuffer. I have a loop in which I use a StringBuffer to avoid creating too many instances of String, but each iteration of the loop I would have my new empty StringBuffer. Any help on this will be appreciated. Thanks for your help.

Hello,
I do not know what exactly you are using the string buffer for, I have a code with me, see if this helps you.
Here is the code

StringBuffer d = new StringBuffer ( "ghjghj");
d.append ( "dsdfsdf"). append ( "sdfsdf");

/ / Empty StringBuffer
d.delete (0, d.length ());

Hope this will help you.

Hello,
Another way is to use the method setLength like this, I do not know that this is what you need.
Here is the method you can use it in your code

mnstring.setLength(0);

What is the expected result of your code? that is what your program needs. I mean to say what is the output you want from your program.

Hello,
I think I misunderstood the delete method, according to the JavaDoc, I thought it returned an stringBuffer, but really did not erase the original stringBuffer. The alternative seems to me very well or I think this is easy to implement in my code, i would rather go with the same. By the way thanks for your replies they helped me a lot and also if you have some more interesting information on the this then please do post back.

Hello,
Most methods StringBuffer return a StringBuffer which in fact corresponds to the current object. In code this is summarized by the following code:

return this;

This allows you to stack calls that same subject:

sb.append("Hello").append(" ").append("World");

Hope the above part of the code will help you. If you need any more explanation regarding this topic then you are free to ask.
