In short, you can overwrite bytes in the middle of a file, but you can't easily replace old stuff with new stuff of a different length. So change and append are easy, but insert and delete are tough. It's common to read all of the old file and write a totally new one with the same or changed content.
See RandomAccessFile if you can be sure the data length doesn't change. Otherwise just read and write with whatever IO works with your data.

A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi
