getting current position from DataInputStream in java

Question

Can anybody tell me how to get the current position of the index while reading the binary file from DataInputStream? I have seen a mark() method but one is Boolean type and the other is void. I need to read the indexes on separate locations to use them again.

Similar questions have been asked before. See for instance this question.

I don't know of any better answer than this:

A simple solution however, would be to roll your own "CountingInputStream" that extends InputStream and counts the number of bytes read. You would basically just need to override the three read-methods.

One could also implement it as a FilterInputStream directly.
