Reasigning variables

Expand Post »

I'm getting StringIndexOutOfBoundsException when I try to reasign the value of a variable.

protString = protString.substring(newRPos+1, input.length());
I understand that this is something I would rather not do... but as I don't know the index of newRPos I can't think of another way to iterate.

Thanks

Re: Reasigning variables

Then also check with if (newRPos < protString.length). Also, is there any guarantee that input.length() is going to be larger than newRPos, as both of those are indexes (i.e. a start index and an end index) not a start and length, and I don't know how substring reacts if the end index is smaller than the start index..

API doc states:

Throws: IndexOutOfBoundsException - if the beginIndex is negative, or endIndex is larger than the length of this String object, or beginIndex is larger than endIndex.

Thanks. That was just me being too lazy to look it up myself, and hoping the OP would figure out to do that. ;-)
