The unmappableCharacterAction() method is a built-in method of the java.nio.charset.CharsetDecoder class which returns this decoder’s current action for unmappable-character errors.

Syntax:

public CodingErrorAction unmappableCharacterAction()

Parameters: The function does not accepts any parameter.

Return Value: The function returns this decoder’s current action for unmappable-character errors.

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("CharsetDecoder: " + decoder);
  
        System.out.println("Current action for "
                           + "unmappable-character errors: "
                           + decoder.unmappableCharacterAction());
    }
}
Output:
CharsetDecoder: sun.nio.cs.ext.ISO2022_CN$Decoder@232204a1
Current action for unmappable-character errors: REPORT

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("CharsetDecoder: " + decoder);
  
        System.out.println("Current action for "
                           + "unmappable-character errors: "
                           + decoder.unmappableCharacterAction());
    }
}
Output:
CharsetDecoder: sun.nio.cs.ext.DoubleByte$Decoder@232204a1
Current action for unmappable-character errors: REPORT
