Question

In other words, I want functionality that provides Joda-Time:

today = today.withTime(0, 0, 0, 0);

but without Joda-Time, only with java.util.Date.

Methods such as .setHours() and etc. are deprecated. Is there are more correct way?

Answer 1

Date today = new Date();
today.setHours(0); //same for minutes and seconds

Since the methods are deprecated, you can do this with Calendar:

Calendar today = Calendar.getInstance();
today.set(Calendar.HOUR_OF_DAY, 0); // same for minutes and seconds

And if you need a Date object in the end, simply call today.getTime()
