| Package | Description | 
|---|---|
| java.io | Provides for system input and output through data streams,
serialization and the file system. | 
| java.nio.channels | Defines channels, which represent connections to entities that are capable of
 performing I/O operations, such as files and sockets; defines selectors, for
 multiplexed, non-blocking I/O operations. | 
| java.nio.charset | Defines charsets, decoders, and encoders, for translating between bytes and
Unicode characters. | 
| Constructor and Description | 
|---|
| OutputStreamWriter(OutputStream out,
                  CharsetEncoder enc)Creates an OutputStreamWriter that uses the given charset encoder. | 
| Modifier and Type | Method and Description | 
|---|---|
| static Writer | Channels. newWriter(WritableByteChannel ch,
         CharsetEncoder enc,
         int minBufferCap)Constructs a writer that encodes characters using the given encoder and
 writes the resulting bytes to the given channel. | 
| Modifier and Type | Method and Description | 
|---|---|
| abstract CharsetEncoder | Charset. newEncoder()Constructs a new encoder for this charset. | 
| CharsetEncoder | CharsetEncoder. onMalformedInput(CodingErrorAction newAction)Changes this encoder's action for malformed-input errors. | 
| CharsetEncoder | CharsetEncoder. onUnmappableCharacter(CodingErrorAction newAction)Changes this encoder's action for unmappable-character errors. | 
| CharsetEncoder | CharsetEncoder. replaceWith(byte[] newReplacement)Changes this encoder's replacement value. | 
| CharsetEncoder | CharsetEncoder. reset()Resets this encoder, clearing any internal state. |
