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:

Program 1:

// Java program to implement
// the above function
import java.nio.CharBuffer;
import java.nio.charset.Charset;
import java.nio.charset.CharsetEncoder;

public class Main {
    public static void main(String[] args) throws Exception
    {
        // Gets the encoder
        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);
    }
}

Output:

sun.nio.cs.US_ASCII$Encoder@232204a1

Program 2:

// Java program to implement
// the above function
import java.nio.CharBuffer;
import java.nio.charset.Charset;
import java.nio.charset.CharsetEncoder;

public class Main {
    public static void main(String[] args) throws Exception
    {
        // Gets the encoder
        CharsetEncoder encoder
            = Charset.forName("UTF8")
                  .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);
    }
}

Output:

sun.nio.cs.UTF_8$Encoder@232204a1
