I get this error "StringIndexOutOfBoundsException" when my input string is st= "Hold State,0,0,0,0,0,0,0,0"

The code below shows what I'm trying to do, create a StingBuffer os size 8 from the input



any ideas?

When you use the constructor of StringBuffer that takes an int parameter, it does not create a StringBuffer with that many characters. It creates a StringBuffer with that capacity.

The StringBuffer will have no characters in it.

Hi Nikos,

Are you trying to split obtained the contents of the comma-delimited String? Read the Java API and you'd notice that StringTokenizer is not recommended for usage anymore, except in supporting legacy codes.

As of JDK 1.4 and later, you could use the split method of String class.



This way, your codes is easier to maintain & understand. There's also performance gain involved, if I'm not mistaken.
