Reading a file larger than 2GB into memory in Java

Question

Since ByteArrayInputStream is limited to 2GB, is there any alternate solution that allows me to store the whole contents of a 2.3GB (and possibly larger) file i

Answer 1

If you have huge quantities of memory, you really won't get any performance improvement anyway. It's only getting read in once either way, and the disk cache will ensure it gets done optimally. Just use a disk-based input stream.
