Charset aliases() method in Java with Examples
  • Last Updated : 28 Mar, 2019

The aliases() method is a built-in method of the java.nio.charset which returns a set containing this charset’s aliases. When an object can be referred by several references, meaning that they store the reference value of the same object, then such references are called aliases.

Syntax:

public final Set aliases()

Parameters: The function does not accepts any parameter.

Return Value: The function returns a set which contains strings that represent charset’s inbuilt aliases.

Below is the implementation of the above function:



Program 1:




// Java program to demonstrate
// the above function
  
import java.nio.charset.Charset;
import java.util.Iterator;
import java.util.Map;
  
public class GFG {
  
    public static void main(String[] args)
    {
  
        // Create a Map which
        // stores all available charsets
        Map<String, Charset> charsets
            = Charset.availableCharsets();
  
        // Declare an iterator
        Iterator<Charset> iterator
            = charsets.values().iterator();
  
        // Iterate till we have aliases
        while (iterator.hasNext()) {
  
            // Get the next iterator
            Charset all = (Charset)iterator.next();
  
            // Print the aliases
            System.out.println(all.aliases());
            System.out.println();
        }
    }
}
