Java Strings use UTF-16 internally, but should be seen as an abstraction without a specific encoding. If you have a String, its already decoded. If you want to encode it, use string.getBytes(encoding). convert from internal Java String format -> UTF-8 public static String convertToUTF 8(String s) String out null try out new String(s.getBytes("UTF-8"), "ISO-8859-1") catchISO-8859-1 encoding is just used to transfer 8 bit array into a String. byte[] ptext myString.getBytes(ISO88591) String value new String(ptext, UTF8) This has the advantage over getBytes(String) that itA Java String is internally always encoded in UTF-16 but you really should think about it like this: an encoding is a way to translate between Strings and bytes. I have included some code that indirectly, via getBytes(String enc), attempts to show what happens using UTF-16 ( Big Endian Unicode, ) the platform default encoding and UTF-8.Files and Directories in Java.
