Converting char array into byte array and back again

Conversion between char and byte is character set encoding and decoding.I prefer to make it as clear as possible in code. It doesn’t really mean extra code volume:

 Charset latin1Charset = Charset.forName("ISO-8859-1"); 
 charBuffer = latin1Charset.decode(ByteBuffer.wrap(byteArray)); // also decode to String
 byteBuffer = latin1Charset.encode(charBuffer);                 // also decode from String

Aside:

java.nio classes and java.io Reader/Writer classes use ByteBuffer & CharBuffer (which use byte[] and char[] as backing arrays). So often preferable if you use these classes directly. However, you can always do:

 byteArray = ByteBuffer.array();  byteBuffer = ByteBuffer.wrap(byteArray);  
 byteBuffer.get(byteArray);       charBuffer.put(charArray);
 charArray = CharBuffer.array();  charBuffer = ByteBuffer.wrap(charArray);
 charBuffer.get(charArray);       charBuffer.put(charArray);
