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 functionimport 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 functionimport 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
