Closeable

This is a source or destination of data that can be closed.

DataInput

This provides for reading bytes from a binary stream and reconstructing from them data in any of the Java primitive types.

DataOutput

This provides for converting data from any of the Java primitive types to a series of bytes and writing these bytes to a binary stream.

Externalizable

This provides only the identity of the class of an Externalizable instance is written in the serialization stream and it is the responsibility of the class to save and restore the contents of its instances.

FileFilter

This is a filter for abstract pathnames.

FilenameFilter

This is a destination of data that can be flushed.

ObjectInput

This extends the DataInput interface to include the reading of objects.

ObjectInputValidation

This is the callback interface to allow validation of objects within a graph.

ObjectOutput

This is the objectOutput extends the DataOutput interface to include writing of objects.

ObjectStreamConstants

The constants written into the Object Serialization Stream.

Serializable

This is enabled by the class implementing the java.io.Serializable interface.
