java: Random Time generator

Question

How do I generate random Time values? For example: 07:02:33, 08:52:14, etc. I know how to generate random numbers but I don't know how to do this. I want to fill my database column TIME with random values.

Answer 1

import java.util.Random;
import java.sql.Time;

final Random random = new Random();
final int millisInDay = 24*60*60*1000;
Time time = new Time((long)random.nextInt(millisInDay));

For your purposes this might be enough. Don't forget that some days have different lengths for which you might need to add test cases (daylight savings and leap seconds).
