More Information
RandomAccessFile provides a way to read from and write to files at any position, similar to how you might access elements in an array using an index.
Tips
A common mistake is treating RandomAccessFile like a standard sequential file stream, which limits its potential. Remember that it acts like an array of bytes, allowing jumps to specific locations.
