Converting Between Strings (Unicode) and Other Character Set Encodings

Demo Code

import java.nio.ByteBuffer;
import java.nio.CharBuffer;
import java.nio.charset.CharacterCodingException;
import java.nio.charset.Charset;
import java.nio.charset.CharsetDecoder;
import java.nio.charset.CharsetEncoder;

public class Main {
  public static void main(String[] argv) throws Exception {
    Charset charset = Charset.forName("ISO-8859-1");
    CharsetDecoder decoder = charset.newDecoder();
    CharsetEncoder encoder = charset.newEncoder();

    try {/*  www.  java 2  s.  c o  m*/
      ByteBuffer bbuf = encoder.encode(CharBuffer.wrap("a string"));
      CharBuffer cbuf = decoder.decode(bbuf);
      String s = cbuf.toString();
    } catch (CharacterCodingException e) {
    }
    ByteBuffer bbuf = ByteBuffer.allocateDirect(1024);

    // Create a non-direct character ByteBuffer
    CharBuffer cbuf = CharBuffer.allocate(1024);

    // Convert characters in cbuf to bbuf
    encoder.encode(cbuf, bbuf, false);

    // flip bbuf before reading from it
    bbuf.flip();

    // Convert bytes in bbuf to cbuf
    decoder.decode(bbuf, cbuf, false);

    // flip cbuf before reading from it
    cbuf.flip();
  }
