Java multithreading reading a single large file

Question

What is an efficient way for a Java multithreaded application where many threads have to read the exact same file (> 1GB in size) and expose it as an input stream? I\'ve notice

Answer 1

Thats a very big file. Can you get the file delivered as a smaller set of files? Just delivering this file will be a big job even on a corporate network.

Sometimes it is easier to change the process than the program.

You may even be better writing something to split the file up into a number of chunks and process them separately.
