Elegant way to read file into byte[] array in Java [duplicate] http://stackoverflow.com/questions/6058003/elegant-way-to-read-file-into-byte-array-in-java FILENAME int read 0 int offset 0 int chunk_size 1024 int total_size 0 ArrayList byte chunks new ArrayList byte chunks.add new byte.. filein.read chunks.get chunks.size 1 offset buffer_size 1 total_size read if read buffer_size chunks.add new byte buffer_size int.. int index 0 then I create big buffer byte rawdata new byte total_size then I copy data from every chunk in this buffer for byte chunk..
