Why is RandomAccessFile not part of the InputStream or OutputStream hierarchies?

Because it allows seeking within a file
Because it operates on text files only
Because it was added in a later Java version
Because it does not support I/O operations

The correct answer is: Because it allows seeking within a file

RandomAccessFile is not part of the InputStream or OutputStream hierarchies because it allows for random access or seeking within a file, meaning it can read or write at any position within a file. This feature is not supported by the other options provided, which either operate on text files only (B), were added in a later Java version (C), or do not support I/O operations (D).
