CharsetDecoder replacement() method in Java with Examples

Last Updated : 27 Jun, 2019

The replacement() method is a built-in method of the java.nio.charset.CharsetDecoder class returns this decoder's replacement value. The replacement value needs to be set inorder to get a valid replacement value. Syntax:

public final Charset replacement()

Parameters: The function does not accepts any parameter. Return Value: The function returns this decoder's replacement value. Below is the implementation of the above function: Program 1:

Java

// 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("CharsetDecoder: " + decoder);

        System.out.println("Replacement Value: "
                           + decoder.replacement());
    }
}

Output:

CharsetDecoder: sun.nio.cs.ext.ISO2022_CN$Decoder@232204a1
Replacement Value: ?

Program 2:

Java

// 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("CharsetDecoder: " + decoder);

        System.out.println("Replacement Value: "
                           + decoder.replacement());
    }
}

Output:

CharsetDecoder: sun.nio.cs.ext.DoubleByte$Decoder@232204a1
Replacement Value: ?
