java - How to convert String into Byte and Back

Question

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?

Answer 1

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");
