Hello friends,

I need an urgent assistance with a project that am working on presently at the moment.

I am trying to read and write data in byte arrays from a file with the use of FileInputStream and then write it to another file with the use of FileOutputStream.

My Code works very fine when handling files lesser than 30MB. When i intend to do such with files above 30MB i get a java.lang.OutOfMemoryError exception and the program stops reading and writing.

In order to be able to avoid this error, i then modified the amount of byte that is being read through FileInputStream to 1MB at a time, so that it keeps reading and writing 1MB of data. But i still get the java.lang.OutOfMemoryError exception and the process stops.

I really need to have this project completed asap. Please help rectify the problem. Below is my code:

I anticipate your prompt response guys.

As our FAQ says, Available Doesnt Do What You Think It Does. Have you looked at
RandomAccessFile or do you have to use streams?
