hi Aruna I'm looking for the Head First C# and Head First Software Development ebooks. it was release recently so till there are no books available in sri lanka i guess. do you have those ebooks?
Uploading ebooks is a good thing because sri lanka gets the books bit late compared to other countries. also the price is bit higher if we buy it online from amazon etc. but i recommend buying the hard copy when it's available in sri lanka. because authors put a great effort to write those books and we have to honor that effort. it's just my opinion. :-)
Hi Mifraz, 100% agree with you. Anyhow I mentioned the books I have in http://groups.google.com/group/java-srilanka-blog/web/ebooks---head-first-series.
If the cost is not a problem please buy the book as Mifraz said.
Useful Links : If u can make another section on resources or links which are useful it will be great. Here a link, seems pretty good (lots of examples)
You can set the initial capacity of StringBuffer using its constructor this improves performance significantly. The constructor is StringBuffer(int length), length shows the number of characters the StringBuffer can hold.
You can even set the capacity using ensureCapacity(int minimumcapacity) after creation of StringBuffer object. Initially we will look at the default behavior and then the better approach later.

Hi Sampath ,
is there a considerable impact on performence of using StringBuffer(int capacity)
over using StringBuffer()...
Optimization by initializing StringBuffer
You can set the initial capacity of StringBuffer using its constructor this improves performance significantly. The constructor is StringBuffer(int length), length shows the number of characters the StringBuffer can hold.
You can even set the capacity using ensureCapacity(int minimumcapacity) after creation of StringBuffer object. Initially we will look at the default behavior and then the better approach later.

for details.
