| Class Summary |
| BufferedInputStream |
A BufferedInputStream adds functionality to another input stream-namely, the ability to buffer the input and to support the mark and reset methods. |
| BufferedOutputStream |
The class implements a buffered output stream. |
| BufferedReader |
Reads text from a character-input stream, buffering characters so as to provide for the efficient reading of characters, arrays, and lines. |
| BufferedWriter |
Writes text to a character-output stream, buffering characters so as to provide for the efficient writing of single characters, arrays, and strings. |
| ByteArrayInputStream |
A ByteArrayInputStream contains an internal buffer that contains bytes that may be read from the stream. |
| ByteArrayOutputStream |
This class implements an output stream in which the data is written into a byte array. |
| CharArrayReader |
This class implements a character buffer that can be used as a character-input stream. |
| CharArrayWriter |
This class implements a character buffer that can be used as an Writer. |
| Console |
Methods to access the character-based console device, if any, associated with the current Java virtual machine. |
| DataInputStream |
A data input stream lets an application read primitive Java data types from an underlying input stream in a machine-independent way. |
| DataOutputStream |
A data output stream lets an application write primitive Java data types to an output stream in a portable way. |
| File |
An abstract representation of file and directory pathnames. |
| FileInputStream |
A FileInputStream obtains input bytes from a file in a file system. |
| FileOutputStream |
A file output stream is an output stream for writing data to a File or to a FileDescriptor. |
| FilePermission |
This class represents access to a file or directory. |
| FileReader |
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 |
Piped character-output streams. |
| PrintStream |
A PrintStream adds functionality to another output stream, namely the ability to print representations of various data values conveniently. |
| PrintWriter |
Prints formatted representations of objects to a text-output stream. |
| PushbackInputStream |
A PushbackInputStream adds functionality to another input stream, namely the ability to "push back" or "unread" one byte. |
| PushbackReader |
A character-stream reader that allows characters to be pushed back into the stream. |
| RandomAccessFile |
Instances of this class support both reading and writing to a random access file. |
| Reader |
Abstract class for reading character streams. |
| SequenceInputStream |
A SequenceInputStream represents the logical concatenation of other input streams. |
| SerializablePermission |
This class is for Serializable permissions. |
| StreamTokenizer |
The StreamTokenizer class takes an input stream and parses it into "tokens", allowing the tokens to be read one at a time. |
| StringBufferInputStream |
Deprecated. This class does not properly convert characters into bytes. |
| StringReader |
A character stream whose source is a string. |
| StringWriter |
A character stream that collects its output in a string buffer, which can then be used to construct a string. |
| Writer |
Abstract class for writing to character streams. |
