| Interface | Description |
|---|---|
| Closeable |
A
Closeable class represents a stream of
data, which can be closed when it is no longer needed. |
| DataInput |
This interface is implemented by classes that can data from streams
into Java primitive types.
|
| DataOutput |
This interface is implemented by classes that can wrte data to streams
from Java primitive types.
|
| FilenameFilter |
This interface has one method which is used for filtering filenames
returned in a directory listing.
|
| Flushable |
A
Flushable class represents a stream of
data, for which internally buffered data can be `flushed'. |
| Serializable |
This interface has no methods.
|
| Class | Description |
|---|---|
| BufferedInputStream |
This subclass of
FilterInputStream buffers input from an
underlying implementation to provide a possibly more efficient read
mechanism. |
| BufferedOutputStream |
This class accumulates bytes written in a buffer instead of immediately
writing the data to the underlying output sink.
|
| 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 allows data to be written to a byte array buffer and
and then retrieved by an application.
|
| CharArrayReader |
This class permits an array of chars to be read as an input stream.
|
| CharArrayWriter |
This class allows data to be written to a char array buffer and
and then retrieved by an application.
|
| 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 |
Implements a file system using pages of flash memory.
|
| FileInputStream |
Reads a stream of bytes from a file.
|
| FileOutputStream |
Writes a stream of bytes to a file.
|
| FileReader |
This class provides a convenient way to set up a
Reader
to read from a file. |
| FileWriter |
This is a convenience class for writing to files.
|
| FilterInputStream |
This is the common superclass of all standard classes that filter
input.
|
| FilterOutputStream |
This class is the common superclass of output stream classes that
filter the output they write.
|
| FilterReader |
This is the common superclass of all standard classes that filter
input.
|
| FilterWriter |
This class is the common superclass of output character stream classes
that filter the output they write.
|
| InputStream |
This abstract class forms the base of the hierarchy of classes that read
input as a stream of bytes.
|
| InputStreamReader | |
| LineNumberReader |
A buffered character-input stream that keeps track of line numbers.
|
| OutputStream |
This abstract class forms the base of the hierarchy of classes that
write output as a stream of bytes.
|
| OutputStreamWriter | |
| PipedInputStream |
An input stream that reads its bytes from an output stream
to which it is connected.
|
| PipedOutputStream |
This class writes its bytes to a
PipedInputStream to
which it is connected. |
| PipedReader |
An input stream that reads characters from a piped writer to which it is
connected.
|
| PipedWriter |
This class writes its chars to a
PipedReader to
which it is connected. |
| PrintStream |
This class prints Java primitive values and object to a stream as
text.
|
| PrintWriter |
This class prints Java primitive values and objects to a stream as
text.
|
| PushbackInputStream |
This subclass of
FilterInputStream provides the ability to
unread data from a stream. |
| PushbackReader |
This subclass of
FilterReader provides the ability to
unread data from a stream. |
| Reader |
This abstract class forms the base of the hierarchy of classes that read
input as a stream of characters.
|
| SequenceInputStream |
This class merges a sequence of multiple
InputStream's in
order to form a single logical stream that can be read by applications
that expect only one stream. |
| StreamTokenizer |
The
StreamTokenizer class takes an input stream and
parses it into "tokens", allowing the tokens to be
read one at a time. |
| 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 |
This abstract class forms the base of the hierarchy of classes that
write output as a stream of chars.
|
| Exception | Description |
|---|---|
| EOFException |
This exception is thrown when the end of the file or stream was
encountered unexpectedly.
|
| FileNotFoundException | |
| InterruptedIOException |
This exception is thrown when a in process I/O operation is interrupted
for some reason.
|
| IOException |
This exception is thrown to indicate an I/O problem of some sort
occurred.
|
| UnsupportedEncodingException |
This exception is thrown when the requested character encoding is
not supported.
|
| UTFDataFormatException |
When reading a UTF string from an input stream, this exception is thrown
to indicate that the data read is invalid.
