Check encoding scheme supported or not in java

'java.nio.charset.Charset' class provides 'isSupported' method to check whether given character encoding is supported by your Java implementation or not.

package com.sample;

import java.io.UnsupportedEncodingException;
import java.nio.charset.Charset;

public class Test {

  public static void main(String args[]) throws UnsupportedEncodingException {

    boolean isUTF8Supported = Charset.isSupported("UTF-8");
    boolean isUTF16Supported = Charset.isSupported("UTF-16");
    boolean isUTF32Supported = Charset.isSupported("UTF-32");
    boolean isUTF64Supported = Charset.isSupported("UTF-64");
    boolean isUTF128Supported = Charset.isSupported("UTF-128");
    boolean isUTF256Supported = Charset.isSupported("UTF-256");

    System.out.println("isUTF8Supported : " + isUTF8Supported);
    System.out.println("isUTF16Supported : " + isUTF16Supported);
    System.out.println("isUTF32Supported : " + isUTF32Supported);
    System.out.println("isUTF64Supported : " + isUTF64Supported);
    System.out.println("isUTF128Supported : " + isUTF128Supported);
    System.out.println("isUTF256Supported : " + isUTF256Supported);
  }
}

Output

isUTF8Supported : true
isUTF16Supported : true
isUTF32Supported : true
isUTF64Supported : false
