CharsetDecoder reset() method in Java with Examples

Last Updated : 27 Jun, 2019

The reset() method is a built-in method of the java.nio.charset.CharsetDecoder class which resets this CharsetDecoder and clears its internal state.

Syntax:

public final CharsetDecoder reset()

Parameters: The function does not accepts any parameter.

Return Value: The function returns this CharsetDecoder after resetting it.

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("Before reset: "
                           + decoder); 
  
        // Reset the CharsetDecoder 
        System.out.println("After reset: "
                           + decoder.reset()); 
    } 
} 
 
  

Output:

  Before reset: sun.nio.cs.ext.ISO2022_CN$Decoder@232204a1  After reset: sun.nio.cs.ext.ISO2022_CN$Decoder@232204a1

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("Before reset: "
                           + decoder); 
  
        // Reset the CharsetDecoder 
        System.out.println("After reset: "
                           + decoder.reset()); 
    } 
} 
 
  

Output:

  Before reset: sun.nio.cs.ext.DoubleByte$Decoder@232204a1  After reset: sun.nio.cs.ext.DoubleByte$Decoder@232204a1
