Classes in java.io used by java.io

Class and Description
BufferedReader Reads text from a character-input stream, buffering characters so as to provide for the efficient reading of characters, arrays, and lines.
Closeable A Closeable is a source or destination of data that can be closed.
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.
File An abstract representation of file and directory pathnames.
FileDescriptor Instances of the file descriptor class serve as an opaque handle to the underlying machine-specific structure representing an open file, an open socket, or another source or sink of bytes.
FileFilter A filter for abstract pathnames.
FilenameFilter Instances of classes that implement this interface are used to filter filenames.
FileNotFoundException Signals that an attempt to open the file denoted by a specified pathname has failed.
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.
Flushable A Flushable is a destination of data that can be flushed.
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.
InvalidObjectException Indicates that one or more deserialized objects failed validation tests.
IOException Signals that an I/O exception of some sort has occurred.
NotActiveException Thrown when serialization or deserialization is not active.
ObjectInput ObjectInput extends the DataInput interface to include the reading of objects.
ObjectInputStream.GetField Provide access to the persistent fields read from the input stream.
ObjectInputValidation Callback interface to allow validation of objects within a graph.
ObjectOutput ObjectOutput extends the DataOutput interface to include writing of objects.
ObjectOutputStream.PutField Provide programmatic access to the persistent fields to be written to ObjectOutput.
ObjectStreamClass Serialization's descriptor for classes.
ObjectStreamConstants Constants written into the Object Serialization Stream.
ObjectStreamException Superclass of all exceptions specific to Object Stream 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.
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.
Reader Abstract class for reading character streams.
Serializable Serializability of a class is enabled by the class implementing the java.io.Serializable interface.
StreamCorruptedException Thrown when control information that was read from an object stream violates internal consistency checks.
StringWriter A character stream that collects its output in a string buffer, which can then be used to construct a string.
SyncFailedException Signals that a sync operation has failed.
UnsupportedEncodingException The Character Encoding is not supported.
Writer Abstract class for writing to character streams.
