The charset() method is a built-in method of the java.nio.charset.CharsetEncoder returns the charset that created this encoder.
Syntax:
public final Charset charset()
Parameters: The function does not accepts any parameter.
Return Value: The function returns this encoder’s charset.
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 CodingErrorAction        System.out.println(encoder.charset());    }} |
Output:
UTF-16
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("UTF8").newEncoder();          // Prints CodingErrorAction        System.out.println(encoder.charset());    }} |
Output:
UTF-8
