  1. import java.util.Date; public class DateDemo { public static void main(String args[]) { // Instantiate a Date object Date date = new Date(); // display time and date using toString () System.out.println(date.toString()); } } This will produce the following result −
  2. LocalDate date = LocalDate.parse ( 2018-05-05 ); A similar approach to the above can be used to convert a String to a java.time. LocalDateTime: LocalDateTime dateTime = LocalDateTime.parse ( 2018-05-05T11:50:55 ); It is important to note that both the LocalDate and LocalDateTime objects are timezone agnostic

To create a file named the current date/time: Date date = new Date() ; SimpleDateFormat dateFormat = new SimpleDateFormat(yyyy-MM-dd HH-mm-ss) ; File file = new File(dateFormat.format(date) + .tsv) ; BufferedWriter out = new BufferedWriter(new FileWriter(file)); out.write(Writing to file); out.close() It provides constructors and methods to deal with date and time with java. Constructors. Date(): Creates date object representing current date and time. Date(long milliseconds): Creates a date object for the given milliseconds since January 1, 1970, 00:00:00 GMT. Date(int year, int month, int date) Date(int year, int month, int date, int hrs, int min Since the String was formatted without the time the Date converted will have the time set to zero. Let's implement it to see how it works: public static Date getDateWithoutTimeUsingFormat() throws ParseException { SimpleDateFormat formatter = new SimpleDateFormat( dd/MM/yyyy); return formatter.parse(formatter.format(new Date())); An instance of current date can be created from the system clock: LocalDate localDate = LocalDate.now(); And we can get the LocalDate representing a specific day, month and year by using the of method or the parse method. For example, these code snippets represent the LocalDate for February 20, 2015

The Date object is a datatype built into the JavaScript language. Date objects are created with the new Date( ) as shown below. Once a Date object is created, a number of methods allow you to operate on it. Most methods simply allow you to get and set the year, month, day, hour, minute, second, and millisecond fields of the object, using either. With Java 8, a new Date-Time API is introduced to cover the following drawbacks of old date-time API. Not thread safe − java.util.Date is not thread safe, thus developers have to deal with concurrency issue while using date.
