String encodedImage = Base64.encodeToString(b, Base64.DEFAULT);
    
Step 1: 
import org.apache.commons.codec.binary.Base64;
String yourString = "testing";
byte[] encoded = Base64.encodeBase64(yourString.getBytes());
    
Step 2:
import javax.xml.bind.DatatypeConverter;
     
 //print hex string version of HELLO WORLD
 byte[] helloBytes = "HELLO WORLD".getBytes();
 String helloHex = DatatypeConverter.printHexBinary(helloBytes);
 System.out.printf("Hello hex: 0x%s\n", helloHex);
     
 //convert hex-encoded string back to original string
 byte[] decodedHex = DatatypeConverter.parseHexBinary(helloHex);
 String decodedString = new String(decodedHex, "UTF-8");
 System.out.printf("Hello decoded : %s\n", decodedString);
    
And heres the program output:
    
Hello hex: 0x48454C4C4F20574F524C44
Hello decoded : HELLO WORLD
