int in the range 0 to 255. If no byte is available
because the end of the stream has been reached, the value -1 is returned.
This read method cannot block.

public int read(byte[] b,

int len)
len bytes of data into an array of bytes from this input stream. If
pos equals count, then -1 is returned to indicate end
of file. Otherwise, the number k of bytes read is equal to the smaller of
len and count-pos. If k is positive, then bytes
buffer[pos] through buffer[pos+k-1] are copied into
b[off] through b[off+k-1] in the manner performed by
System.arraycopy. The value k is added into pos and
k is returned. This read method cannot block.
