Java 8: Base64 Encoding & Decoding [snippet]

The Base64 encoding and decoding is a long overdue JDK API feature. As part of Java 8 the Base64 encoding and decoding feature came into the Java standard library.

The Base64 encoding and decoding is a long overdue JDK API feature. As part of Java 8 the Base64 encoding and decoding feature came into the Java standard library. Earlier we were using private and unsupported sun.misc.BASE64Encoder and sun.misc.BASE64Decoder classes which are not part of the standard API. In Java 8, we got the java.util.Base64 class to perform Base64 encoding and decoding. The sample code on Base64 usage is given below.

package org.smarttechie;

import java.io.UnsupportedEncodingException;
import java.util.Base64;

public class Base64Sample {
public static void main(String args[]){

String str = "Welcome to see java.util.Base64";
Base64.Encoder base64Encoder= Base64.getEncoder();

//encoding byte array into base 64
byte[] byteArray = null;
try {
    byteArray = base64Encoder.encode(str.getBytes("UTF-8"));
    System.out.println("Base64 Encoded String : " + new String(byteArray,"UTF-8"));

    //decoding byte array into base64
    Base64.Decoder base64Decoder= Base64.getDecoder();
    byte[] strdec=base64Decoder.decode(byteArray);

   System.out.println("Base64 Decoded String : " + new String(strdec,"UTF-8"));
  } catch (UnsupportedEncodingException e) {
      e.printStackTrace();
   }
  }
}
