How to Format Date and Time in the Java 8 Date/Time API

import java.time.*;
import java.time.format.*;
public class FormattingDateAndTime {
	public static void main (String args[]) {
		// Create a local date time object:
		LocalDateTime today=LocalDateTime.now();
		DateTimeFormatter formatToday=DateTimeFormatter.ofPattern("MM/dd/yy hh:mm:ss");
		//String formattedToday=today.format(formatToday);
		System.out.format("Formatted date time is %s\n", today.format(formatToday));
		
		// Create a local time object:
		LocalTime timeNow=LocalTime.now();
		DateTimeFormatter formatTimeNow=DateTimeFormatter.ofPattern("HH:mm:ss a");
		System.out.format("Formatted current time is %s\n", timeNow.format(formatTimeNow));
		
		// Create a local date object:
		LocalDate dateToday=LocalDate.now();
		DateTimeFormatter formatDateToday=DateTimeFormatter.ofPattern("EEEE MMM dd ");
		System.out.format("Formatted current date is %s\n" , dateToday.format(formatDateToday));	
	}
}

The DateTimeFormatter class can be used to format date/time objects. The ofPattern method specifies the pattern. The pattern consists of characters that have a special meaning to the formatter. For example, a pattern of MM indicates that a two-digit month number is to be displayed (e.g., the month number of February is "02"). Patterns like M can imply a numeric value or a text value. If you specify MMM then the text value of the month abbreviation will be generated (e.g., "Feb"). A specification of MMMM would generate the complete month name (e.g., "February"). The E pattern applies to weekday names. Coding E yields the first character of the weekday name (e.g., "W" for Wednesday). The EEE pattern results in the abbreviation of the weekday name (e.g., "Wed" for Wednesday). If you use EEEE then the weekday name (e.g., "Wednesday") is generated.

For time patterns, use mm for two-digit minute and ss for two-digit second. The hh pattern generates the two-digit hour for a 12-hour clock (e.g., 6PM is "06") and HH generates the two-digit hour for a 24-hour clock (e.g., 6PM is "18"). The a requests "AM" (between midnight and noon) or "PM" (between noon and midnight).
