CharsetEncoder replacement() method in Java with Examples

Last Updated : 29 Mar, 2019

The replacement() method is a built-in method of the java.nio.charset.CharsetEncoder returns a byte array which is the replacement value of the encoder.

Syntax:

public final byte[] replacement()

Parameters: The function does not accepts any parameter.

Return Value: The function returns this encoder’s current replacement, which is never null and is never empty.

Below is the implementation of the above function:

Program 1:

// Java program to implement 
// the above function 
import java.nio.CharBuffer; 
import java.nio.charset.Charset; 
import java.nio.charset.CharsetEncoder; 
  
public class Main { 
    public static void main(String[] args) throws Exception 
    { 
        // Gets the encoder 
        CharsetEncoder encoder = Charset.forName("UTF16").newEncoder(); 
  
        // Prints byte array representing 
        // the replacement value 
        System.out.println(encoder.replacement()); 
    } 
} 

Output:

[B@232204a1

Program 2:

// Java program to implement 
// the above function 
import java.nio.CharBuffer; 
import java.nio.charset.Charset; 
import java.nio.charset.CharsetEncoder; 
  
public class Main { 
    public static void main(String[] args) throws Exception 
    { 
        // Gets the encoder 
        CharsetEncoder encoder = Charset.forName("US-ASCII").newEncoder(); 
  
        // Prints byte array representing 
        // the replacement value 
        System.out.println(encoder.replacement()); 
    } 
} 

Output:

[B@232204a1
