I would like to read an array of integer values ( or floats, etc) from a RandomAccessFile. However, the options for this type of file include an array of bytes, or a single integer at a time. I looked at the tutorial http://java.sun.com/docs/books/tutorial/ but now am even more confused. I'm guessing that it should be possible to read an array of bytes, write them to some output stream (in memory?), and then sequentially read my sequence of integers from an input stream connected to the output stream? All I know for certain is that reading 30000 integers from the file one at a time is very slow. Does anyone have any idea how to implement this, or (even better?) point me to a reference that discusses how to chain input/output streams to accomplish this. Thanks, Dave Hopkins ARL hopkins@arl.mil
