| Packages that use java.io | |
| java.io | Provides classes for input and output through data streams. |
| java.lang | Provides classes that are fundamental to the Java programming language. |
| javax.microedition.io | Classes for the Generic Connection framework. |
| javax.microedition.lcdui | The UI API provides a set of features for implementation of user interfaces for MIDP applications. |
| javax.microedition.media | The MIDP 2.0 Media API is a directly compatible building block of the Mobile Media API (JSR-135) specification. |
| javax.microedition.pki | Certificates are used to authenticate information for secure Connections. |
| 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. |
