132. Serializing objects to strings

In the previous problem, you saw how to serialize objects to byte arrays. If we work a little bit on a byte array, we can obtain a string representation of serialization. For instance, we can rely on java.util.Base64 to encode a byte array to String as follows:

public static String objectToString(Serializable obj) throws IOException {       
    
    try ( ByteArrayOutputStream baos = new ByteArrayOutputStream();
          ObjectOutputStream ois = new ObjectOutputStream(baos)) {
        ois.writeObject(obj);
        
        return Base64.getEncoder().encodeToString(baos.toByteArray());
    }                
}

A possible output looks like this:

And, the code to obtain such a String is as follows:

String melonSer = Converters.objectToString(melon);

The reverse process relies on the Base64 decoder as...
