CharsetDecoder isAutoDetecting() method in Java with Examples

The isAutoDetecting() method is a built-in method of the java.nio.charset.CharsetDecoder class which tells whether or not this decoder implements an auto-detecting charset.

Syntax:

public boolean isAutoDetecting()

Parameters: The function does not accepts any parameter.

Return Value: The function returns a boolean value stating if this CharsetDecoder implements ab auto-detecting charset.

        System.out.println("Is CharsetDecoder auto-detecting: "
                           + decoder.isAutoDetecting());
    }
}
