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

      Properties properties = new Properties();


      if (sProperties != null)
      {
         Charset charset = Charset.forName(IOUtil.ENCODING);
         ByteBuffer byteBuffer = charset.encode(sProperties);
         ByteArrayInputStream is = new ByteArrayInputStream(byteBuffer.array(), 0, byteBuffer.limit());
   
         properties.load(is);
