Java does not have a built-in Date class, but we can import the java.time package to work with the date and time API. The package includes many date and time classes. For example: If you don't know what a package is, read our Java Packages Tutorial. To display the current date, import the java.time.LocalDate class, and use its now() method:

The better way would be to convert the String array to an array of Date. Date[] arrayOfDates = new Date[dates.length]; for (int index = 0; index < dates.length; index++) { arrayOfDates[index] = sdf.parse(dates[index]); } Then sort the arrayOfDates and if you need to, use the SimpleDateFormat to format the results back to the dates array...

public class A { private Date dateTime; public Date getDateTime() { return dateTime; } .... other variables } And let's say you have a list of A objects as List<A> aList, you can easily sort it with Java 8's stream API (snippet below): import java.util.Comparator; import java.util.stream.Collectors; ...
