Classes in java.io used by java.io

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

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

InputStream
This abstract class is the superclass of all classes representing an input stream of bytes.

IOException
Signals that an I/O exception of some sort has occurred.

OutputStream
This abstract class is the superclass of all classes representing an output stream of bytes.

Reader
Abstract class for reading character streams.

UnsupportedEncodingException
The Character Encoding is not supported.

Writer
Abstract class for writing to character streams.

Classes in java.io used by java.lang

InputStream
This abstract class is the superclass of all classes representing an input stream of bytes.

PrintStream
A PrintStream adds functionality to another output stream, namely the ability to print representations of various data values conveniently.

UnsupportedEncodingException
The Character Encoding is not supported.

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

DataInputStream
A data input stream lets an application read primitive Java data types from an underlying input stream in a machine-independent way.

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

DataOutputStream
A data output stream lets an application write primitive Java data types to an output stream in a portable way.

InputStream
This abstract class is the superclass of all classes representing an input stream of bytes.

IOException
Signals that an I/O exception of some sort has occurred.

OutputStream
This abstract class is the superclass of all classes representing an output stream of bytes.
