Question: 1 / 510

What interface do DataInputStream and DataOutputStream implement?

DataInput and DataOutput

DataInputStream and DataOutputStream implement the DataInput and DataOutput interface as they provide methods to perform operations on data inputs and outputs respectively. The other options, InputStream and OutputStream, are superinterfaces of DataInputStream and DataOutputStream, but they do not provide specific methods for managing data input and output. Reader and Writer are interfaces for reading and writing characters, not raw binary data like DataInputStream and DataOutputStream do. Finally, Serializable is an interface used for classes that require serialization, which is not specific for input or output operations.
