copy

public static void copy(byte[] input,
                        java.io.OutputStream output)
                 throws java.io.IOException

Copy bytes from a byte[] to an OutputStream.

Parameters:

input - the byte array to read from

output - the OutputStream to write to

Throws:

java.io.IOException - In case of an I/O problem

copy

public static void copy(byte[] input,
                        java.io.Writer output)
                 throws java.io.IOException

Copy and convert bytes from a byte[] to chars on a Writer. The platform's default encoding is used for the byte-to-char conversion.
