how to convert timestamp to date in java

Question

Java

Good day! I am new to java. I can't find a solution specifically for my problem.
There is a String in which there is a timestamp ("1406050791" for example).
You need to convert it (preferably to String) into a readable form like "dd.MM.yyyy HH:mm".
Thank you.

Answer 1

I would do it this way

Answer 2

The "optimized" version of the option suggested by jack
Calendar is IMHO redundant, java.util.Date is sufficient.
