How to get date and time in java?

We frequently need to work with date and time while doing software development.

We need date and time as DoB, Order date, Event time, created,last_updated, etc. In this article, we will learn how to get the current time of the day in Java applications.

Java provides the Date and Calendar classes to manipulate date and Time.

We can use the SimpleDateFormat class to format the time accordingly.

The new java.time package contains a number of classes that can be used for creating Date,which is pretty easy.

Get current Date in Java

 
import java.time.LocalDate;

public class LocalDateExample {
    public static void main(String[] args) {
        LocalDate currentDate = LocalDate.now();
        System.out.println("TheCurrent Date is: "+currentDate);
    }
}

output:
TheCurrent Date is: 2020-06-21

Get current Date and Time in Java

 
import java.time.LocalDateTime;

public class CurrentDateTime {
    public static void main(String[] args) {
        LocalDateTime currentDateTime = LocalDateTime.now();
        System.out.println("Current Date and time is : " + currentDateTime);
    }
}
output:
Current Date and time is : 2020-06-21T19:58:32.274

How to get the current date in java 8?

 
package com.javacodestuffs.datetime;

import java.time.LocalDate;

import java.time.ZonedDateTime;
 
public class CurrentDateTimeExample {
 
    public static void main(String a[]) {
 
        
        LocalDate localDate = LocalDate.now();
        System.out.println("Current date without time : "+localDate);
 
      
        LocalTime localTime = LocalTime.now();
        System.out.println("Current time without date : "+localTime);
 
      
        LocalDateTime localDateTime = LocalDateTime.now();
        System.out.println("Current date & time without zone : "+localDateTime);
 
        
        ZonedDateTime zonedDateTime = ZonedDateTime.now();
        System.out.println("Current date & time with zone : "+zonedDateTime);
    }
}
output:
$javac com/javacodestuffs/datetime/CurrentDateTimeExample.java
$java -Xmx128M -Xms16M com/javacodestuffs/datetime/CurrentDateTimeExample
Current date without time : 2020-06-21
Current time without date : 21:02:00.912
Current date & time without zone : 2020-06-21T21:02:00.912
Current date & time with zone : 2020-06-21T21:02:00.913Z[Etc/UTC]

LocalDate currentDate = LocalDate.now();
System.out.println(currentDate);
