Get Current Date and Time in Java

import java.time.LocalDateTime;
public class CurrentDateTime {
   public static void main(String[] args) {
        LocalDateTime current = LocalDateTime.now();
        System.out.println("Current Date and Time is: " + current);
    }
} 

Current Date and Time is: 2020-11-28 T13:04:31.579 

• This program is used to get the current date and time by using the time package in Java.
• The LocalDateTime class is used for initializing a variable current that holds a LocalDateTime method LocalDateTime.now(). This method is used to store the current date and time in the variable current.
•  Finally, for displaying the current date and time in the default format, the LocalDateTime object is internally converted into a string through the toString() method.

import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
 
public class CurrentDateTime {
 public static void main(String[] args) {
        LocalDateTime current = LocalDateTime.now();
 
  DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS");
        String formatted = current.format(formatter);
        System.out.println("Current Date and Time is: " + formatted);
    }
} 

Current Date and Time is: 2020-11-28 13:06:57.489

• This program is used for getting and displaying the current date and time pattern specified through a formatter.
• For a specific format, the DateTimeFormatter class of the java.time package is used. The pattern of the format Year-Month-Day Hours:Minutes:Seconds:Milliseconds is specified in the program through the DateTimeFormatter object and stored in the formatter variable.
• After the pattern format specification, the format() method of the LocalDateTime class is used to make the program use the defined formatter.
• Finally, the program gets the local date time in the pattern according to the formatter.

import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
 
public class CurrentDateTime {
   public static void main(String[] args) {
   LocalDateTime current = LocalDateTime.now();
   DateTimeFormatter formatter = DateTimeFormatter.BASIC_ISO_DATE;
        String formatted = current.format(formatter);
 
        System.out.println("Current Date is: " + formatted);
    }
} 

Current Date is: 20201128

• This program is used to get the local data and time by using the predefined constant BASIC_ISO_DATE.
• A formatter variable is initialized through the DateTimeFormatter class and holds a predefined constant of a format, BASIC_ISO_DATE that is used to get the date and time in the current ISO date format.
• After the ISO date format specification, the format() method of the LocalDateTime class is used to make the program use the defined formatter.
• Finally, the program gets the local date time in the ISO date format according to the formatter.

import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
 
public class CurrentDateTime {
     public static void main(String[] args) {
     LocalDateTime current = LocalDateTime.now();
     DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS");
        String formatted = current.format(formatter);
        System.out.println("Current Date and Time is: " + formatted);
    }
}

• This program is used for getting the local date and time in a localized style by using the .oflocalizedDateTime() method.
• A formatter variable is initialized through the DateTimeFormatter class and holds a .oflocalizedDateTime() method of the DateTimeFormatter class. A format style Medium is set inside the method through the FormatStyle class of the java.time package in order to get the current date and time in the specified localized format.
• After the localized format specification, the format() method of the LocalDateTime class is used to make the program use the defined formatter.
• Finally, the program gets the local date time in the localized medium format according to the formatter.
• However, there are other format styles (Full, Long and Short) that can used with the formatstyle object to set the localized format of date and time.
