CharsetDecoder reset() method in Java with Examples

The reset() method is a built-in method of the java.nio.charset.CharsetDecoder class which resets this CharsetDecoder and clears its internal state.

Syntax:

public final CharsetDecoder reset()

Parameters: The function does not accepts any parameter.

Return Value: The function returns this CharsetDecoder after resetting it.

Below is the implementation of the above function:

Program 1:

// Java program to demonstrate
// the above function

import java.nio.charset.*;
import java.util.Iterator;
import java.util.Map;

public class GFG {

    public static void main(String[] args)
    {

        // Gets the charset
        Charset charset
            = Charset.forName("ISO-2022-CN");

        // Get the CharsetDecoder
        CharsetDecoder decoder
            = charset.newDecoder();

        // Prints the CharsetDecoder
        System.out.println("Before reset: "
                           + decoder);

        // Reset the CharsetDecoder
        System.out.println("After reset: "
                           + decoder.reset());
    }
}

Output:

Before reset: sun.nio.cs.ext.ISO2022_CN$Decoder@232204a1
After reset: sun.nio.cs.ext.ISO2022_CN$Decoder@232204a1

Program 2:

// Java program to demonstrate
// the above function

import java.nio.charset.*;
import java.util.Iterator;
import java.util.Map;

public class GFG {

    public static void main(String[] args)
    {

        // Gets the charset
        Charset charset
            = Charset.forName("x-windows-949");

        // Get the CharsetDecoder
        CharsetDecoder decoder
            = charset.newDecoder();

        // Prints the CharsetDecoder
        System.out.println("Before reset: "
                           + decoder);

        // Reset the CharsetDecoder
        System.out.println("After reset: "
                           + decoder.reset());
    }
}

Output:

Before reset: sun.nio.cs.ext.DoubleByte$Decoder@232204a1
After reset: sun.nio.cs.ext.DoubleByte$Decoder@232204a1
