For converting a string, I am converting it into a byte as follows:
byte[] nameByteArray = cityName.getBytes();
To convert back, I did: String retrievedString = new String(nameByteArray); which obviously doesn't work. How would I convert it back?

How to convert String to byte[] in Java? In Java, we can use str. getBytes(StandardCharsets. UTF_8) to convert a String into a byte[] .
Byte objects are sequence of Bytes, whereas Strings are sequence of characters. Byte objects are in machine readable form internally, Strings are only in human readable form. Since Byte objects are machine readable, they can be directly stored on the disk.
What characters are there in your original city name? Try UTF-8 version like this:
byte[] nameByteArray = cityName.getBytes("UTF-8");
String retrievedString = new String(nameByteArray, "UTF-8");
