I am using FileInputStream to find a position in a file and would like to edit a perticular record when all criteria is met. How do I change from a FileInputStream to a FileOutputStream without loosing my file pointer?

I don't think you can do this without reading from the input and writing to the output until you hit the record you want, then writing the new record and finally continuing reading/writing (ie. effectively copying the file).

If you want to jump in to the middle of a file and do editing, you should probably be using a RandomAccessFile.
