In Java, you can display the current date and time using the System.currentTimeMillis() method or the java.time package, which was introduced in Java 8. Here are some examples:
Using System.currentTimeMillis()
You can get the current time in milliseconds since the Unix Epoch (January 1, 1970) using the System.currentTimeMillis() method. You can then create a java.sql.Date object using this value to display the current date.
Here’s an example:
long millis=System.currentTimeMillis();
java.sql.Date date=new java.sql.Date(millis);
System.out.println(date);Using java.time package
The java.time package provides several classes for working with dates and times, such as LocalDateTime, LocalDate, LocalTime, and ZonedDateTime.
Here are some examples:
LocalDateTime
This method returns the current date and time:
System.out.println(java.time.LocalDateTime.now());Local Date
This method simply returns the current date:
LocalDate date = LocalDate.now();LocalTime
This method simply returns the current time and can be formatted:
LocalTime time = LocalTime.now();ZonedDateTime
This method is used according to the time zone and can be implemented in the following way:
ZonedDateTime dateTime = ZonedDateTime.now();Here’s an example program that displays the current date and time using the java.time package:
import java.time.LocalDateTime;
import java.time.LocalDate;
import java.time.LocalTime;
import java.time.ZonedDateTime;
public class Main {
public static void main(String[] args) {
// Get current date and time
LocalDateTime now = LocalDateTime.now();
System.out.println("Current date and time: " + now);
// Get current date
LocalDate date = LocalDate.now();
System.out.println("Current date: " + date);
// Get current time
LocalTime time = LocalTime.now();
System.out.println("Current time: " + time);
// Get current date and time with time zone
ZonedDateTime zone = ZonedDateTime.now();
System.out.println("Current date and time with time zone: " + zone);
}
}When you run this program, it will display the current date and time in your local time zone.
