How to convert Date/Time to a Date in Salesforce?

We can create a date newInstance() and pass the year, month, day from the DateTime to convert DateTime to date. e.g:
DateTime dTime= System.now();
Date newDate = date.newinstance(dTime.year(), dTime.month(), dTime.day());
OR, we can also use Date() method to convert DateTime to date. E.g.:
DateTime dTime= System.now();
Date newDate = dTime.date();
