21. what is the diffrence between readUnsignedByte() and read() of DataInputStream coderanch.comreadUnsignedByte, like all other methods specified by the DataInput interface, throws an EOFException if the end of the stream was reached. The method read doesn't throw an exception but returns -1. Both are required in DataInputStream because it is an InputStream that implements the DataInput interface (and thus must have both methods). |
