There is an exact question in the exam scam book from B.Brogden. Here is his explanation:
"....there is no way to create a RandonAccessFile from a URL. The basic reason is that there is no protocol for random access to files via HTTP."

I don't think this is a correct reason. A URL may not necessarily use HTTP.
The reason you cannot have random access to a URL is:
There is no concept of a "File Pointer" that you can move around in a URL. All you have is a stream of data. You do not have a "chunk" of data. Furthermore, you can have random access only if you have all the data buffered so that you can move the File Pointer around in that buffer.
