CharsetDecoder averageCharsPerByte() method in Java with Examples

The averageCharsPerByte() method is a built-in method of the java.nio.charset.CharsetDecoder class which returns the average number of characters that will be produced for each byte of input. This heuristic value may be used to estimate the size of the output buffer required for a given input sequence.

Syntax:

public final float averageCharsPerByte()

Parameters: The function does not accepts any parameter.

Return Value: The function returns the average number of characters that will be produced for each byte of input.

Below is the implementation of the above function:

    {
  
        // Gets the charset
        Charset charset = Charset.forName("ISO-2022-CN");
  
        // Get the CharsetDecoder
        CharsetDecoder decoder = charset.newDecoder();
  
        // Prints the averageCharsPerByte
        System.out.println("The averageCharsPerByte "
                           + "for ISO-2022-CN is "
                           + decoder.averageCharsPerByte());
    }
}
