Reader

It is used for reading character stream.

SequenceInputStream

It represents the logical concatenation of other input stream.

SerializablePermission

This is a serializable permission class.

StreamTokenizer

It takes an input stream and parses it into “tokens”. The token to be allowed at the read time.

StringWriter

This is also a character string class. It uses to shows the output in the buffer.

Writer

It is used for writing to character stream.

Interface

Description

DataInput

This interface can be used for reading byte stream and reconstructing the java primitive data types.
