Convenience class for reading character files.
|
FileWriter |
Convenience class for writing character files.
|
FilterInputStream |
A
FilterInputStream contains
some other input stream, which it uses as
its basic source of data, possibly transforming
the data along the way or providing additional
functionality. |
FilterOutputStream |
This class is the superclass of all classes that filter output
streams.
|
FilterReader |
Abstract class for reading filtered character streams.
|
FilterWriter |
Abstract class for writing filtered character streams.
|
InputStream |
This abstract class is the superclass of all classes representing
an input stream of bytes.
|
InputStreamReader |
An InputStreamReader is a bridge from byte streams to character streams: It
reads bytes and decodes them into characters using a specified
charset . |
LineNumberInputStream | Deprecated
This class incorrectly assumes that bytes adequately represent
characters.
|
LineNumberReader |
A buffered character-input stream that keeps track of line numbers.
|
ObjectInputStream |
An ObjectInputStream deserializes primitive data and objects previously
written using an ObjectOutputStream.
|
ObjectInputStream.GetField |
Provide access to the persistent fields read from the input stream.
|
ObjectOutputStream |
An ObjectOutputStream writes primitive data types and graphs of Java objects
to an OutputStream.
|
ObjectOutputStream.PutField |
Provide programmatic access to the persistent fields to be written
to ObjectOutput.
|
ObjectStreamClass |
Serialization's descriptor for classes.
|
ObjectStreamField |
A description of a Serializable field from a Serializable class.
|
OutputStream |
This abstract class is the superclass of all classes representing
an output stream of bytes.
|
OutputStreamWriter |
An OutputStreamWriter is a bridge from character streams to byte streams:
Characters written to it are encoded into bytes using a specified
charset . |
PipedInputStream |
A piped input stream should be connected
to a piped output stream; the piped input
stream then provides whatever data bytes
are written to the piped output stream.
|
PipedOutputStream |
A piped output stream can be connected to a piped input stream
to create a communications pipe.
|
PipedReader |
Piped character-input streams.
|
PipedWriter |

namely the ability to print representations of various data values
conveniently. |

|
PushbackInputStream |
A
PushbackInputStream adds

the ability to "push back" or "unread"
one byte. |

stream.
|
RandomAccessFile |
Instances of this class support both reading and writing to a
random access file.
|

|
SequenceInputStream |
A
SequenceInputStream represents
the logical concatenation of other input
streams. |
SerializablePermission |

A character stream whose source is a string.
|

|
Writer |
Abstract class for writing to character streams.
|
