public static void dump(byte data, long offset, OutputStream stream, int index) throws IOException, ArrayIndexOutOfBoundsException, IllegalArgumentException
The offset argument specifies the start offset of the data array within a larger entity like a file or an incoming stream. For example, if the data array contains the third kibibyte of a file, then the offset argument should be set to 2048. The offset value printed at the beginning of each line indicates where in that larger entity the first byte on that line is located.
All bytes between the given index (inclusive) and the end of the data array are dumped.
data- the byte array to be dumped
offset- offset of the byte array within a larger entity
stream- the OutputStream to which the data is to be written
index- initial index into the byte array
IOException- is thrown if anything goes wrong writing the data to stream
ArrayIndexOutOfBoundsException- if the index is outside the data array's bounds
IllegalArgumentException- if the output stream is null
