Could you tell the reason of using RandomAccessFile? Why it's better when I want to append some content to a file?

Could you tell the reason of using RandomAccessFile?

Sometimes stream-based access just doesn't cut it. For example, if you were implementing a database you might have a table represented as a file with fixed-width records. The ability to change properties of that record in place without opening an OutputStream and rewriting the entire file from scratch is very significant.

Why it's better when I want to append some content to a file?

It's not.

Thank you David. I've just read the API documents again and see what you mean. File Pointer makes things more efficient and easy in some certain situations
 
Is this the real life? Is this just fantasy? Is this a tiny ad?
