CharsetEncoder reset() method in Java with Examples

The reset() method is a built-in method of the java.nio.charset.CharsetEncoder resets this encoder, and clears all the internal states if there are any. It also resets charset-independent state and also invokes the implReset method in order to perform any charset-specific reset actions.

Syntax:

public final CharsetEncoder reset()

Parameters: The function does not accepts any parameter.



Return Value: The function resets a particular encoder.

Below is the implementation of the above function:

        CharsetEncoder encoder
            = Charset.forName("US-ASCII")
                  .newEncoder();
  
        // It will reset the encoder
        // and clear all internal activities if there are
        encoder.reset();
  
        // Prints the encoder after resetting it
        System.out.println(encoder);
    }
}
