Charset.availableCharsets() in Java

Charset.availableCharsets(): This method is available in java.nio.charset.Charset class of Java.

Syntax:

SortedMap<String, Charset> java.nio.charset.Charset.availableCharsets()

This method constructs a sorted map from canonical charset names to charset objects. The map returned by this method will have one entry for each charset for which support is available in the current Java virtual machine.

Note: This method may return different results at different times if new charset providers are dynamically made available to the current Java virtual machine.

Returns: An immutable, case-insensitive map from canonical charset names to charset objects

Approach

Java

import java.nio.charset.Charset;

public class CharsetavailableCharsets {
    public static void main(String[] args) {

        System.out.println("There are " + 
      Charset.availableCharsets().size() + 
       " available Charsets");
    }
}

Output:

There are 173 available Charsets
