Examples of java.nio.charset.Charset.encode()

java.nio.charset.Charset.encode()
Encodes the content of the give character buffer and outputs to a byte buffer that is to be returned.
The default action in case of encoding errors is CodingErrorAction.REPLACE.
@param buffer the character buffer containing the content to be encoded @return the result of the encoding

  public static byte[] getBytes (char[] chars) {
    Charset cs = Charset.forName ("UTF-8");
    CharBuffer cb = CharBuffer.allocate (chars.length);
    cb.put (chars);
                cb.flip ();
    ByteBuffer bb = cs.encode (cb);
    
    return bb.array();
        }
 
  public static char[] getChars (byte[] bytes) {
