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
