I'm used to using streams in C++ where you can seek negatively, in java however it appears you can only seek positively. Does this mean a negative seek can only be achieved using a reset() and seek(with a positive argument), to have the effect of a negative seek. (Isn't that very in-efficient with buffers?)
InputStream doesn't have seek. It does have skip. Most streams are not random access. Most uses of stream-like objects do not require random access behaviour. So it doesn't make a great deal of sense to have a seek method.
What you probably want is RandomAccessFile.
