reading buffered binary file (with seek)

Question

Say I need to read huge binary file of integers, a handy way is:

FileInputStream fi = new FileInputStream(file);
BufferedInputStream bi = new BufferedInput         


        

Answer 1

Have a look at NIO. For example, java.nio.MappedByteBuffer.

Answer 2

Just start with fi.skip(position) before wrapping it with bi and di. The underlying stream actually makes a call to seek when position is sufficiently large.
