Description
Interface Summary | |
---|---|
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. |
Class Summary | |
---|---|
BufferedReader | Read text from a character-input stream, buffering characters so as to provide for the efficient reading of characters, arrays, and lines. |
BufferedWriter | Write 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. |
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. |
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 translates them into characters. |
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 translated into bytes. |
PrintStream | A PrintStream adds functionality to another output stream,
namely the ability to print representations of various data values
conveniently. |
PrintWriter | Print formatted representations of objects to a text-output stream. |
Reader | Abstract class for reading character streams. |
Writer | Abstract class for writing to character streams. |
Exception Summary | |
---|---|
EOFException | Signals that an end of file or end of stream has been reached unexpectedly during input. |
InterruptedIOException | Signals that an I/O operation has been interrupted. |
IOException | Signals that an I/O exception of some sort has occurred. |
UnsupportedEncodingException | The Character Encoding is not supported. |
UTFDataFormatException | Signals that a malformed UTF-8 string has been read in a data input stream or by any class that implements the data input interface. |
Provides classes for input and output through data streams. Unless otherwise noted, passing a null argument to a constructor or method in any class or interface in this package will cause a NullPointerException to be thrown.
