| Charset | A charset is a named mapping between Unicode characters and byte sequences. | 
| CharsetDecoder | A converter that can convert a byte sequence from a charset into a 16-bit Unicode character sequence. | 
| CharsetEncoder | Transforms a sequence of 16-bit Java characters to a byte sequence in some encoding. | 
| CoderResult | Used to indicate the result of encoding/decoding. | 
| CodingErrorAction | Used to indicate what kind of actions to take in case of encoding/decoding errors. | 
| CharacterCodingException | A CharacterCodingException is thrown when an encoding or decoding
 error occurs.  | 
          
| IllegalCharsetNameException | An IllegalCharsetNameException is thrown when an illegal charset name
 is encountered.  | 
          
| MalformedInputException | A MalformedInputException is thrown when a malformed input is
 encountered, for example if a byte sequence is illegal for the given charset.  | 
          
| UnmappableCharacterException | An UnmappableCharacterException is thrown when an unmappable
 character for the given charset is encountered.  | 
          
| UnsupportedCharsetException | An UnsupportedCharsetException is thrown when an unsupported charset
 name is encountered.  | 
          
| CoderMalfunctionError | A CoderMalfunctionError is thrown when the encoder/decoder is
 malfunctioning.  |
