Writer of files that allows the encoding to be set.
This class provides a simple alternative to FileWriter
that allows an encoding to be set. Unfortunately, it cannot subclass
FileWriter
.
By default, the file will be overwritten, but this may be changed to append.
The encoding must be specified using either the name of the Charset
,
the Charset
, or a CharsetEncoder
. If the default encoding
is required then use the FileWriter
directly, rather than
this implementation.
