CharsetDecoder malformedInputAction() method in Java with Examples

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

Syntax:

public CodingErrorAction malformedInputAction()

Parameters: The function does not accepts any parameter.

Return Value: The function returns this decoder’s current action for malformed-input 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 "
                           + "malformed-input errors: "
                           + decoder.malformedInputAction());
    }
}

Output:

CharsetDecoder: sun.nio.cs.ext.ISO2022_CN$Decoder@232204a1
Current action for malformed-input 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 "
                           + "malformed-input errors: "
                           + decoder.malformedInputAction());
    }
}

Output:

CharsetDecoder: sun.nio.cs.ext.DoubleByte$Decoder@232204a1
Current action for malformed-input errors: REPORT
