How to convert / cast long to String?
See the reference documentation for the String class: String s = String.valueOf(date);
If your Long might be null and you don't want to get a 4-letter "null" string, you might use Objects.toString, like: String s = Objects.toString(date, null);
EDIT:
You reverse it using Long l = Long.valueOf(s); but in this direction you need to catch NumberFormatException
String strLong = Long.toString(longNumber);Simple and works fine :-)
Long.toString()
The following should work:
long myLong = 1234567890123L;String myString = Long.toString(myLong);
