    // 1. Get today's date
    LocalDate today = LocalDate.now(); 
    System.out.println("Today's Local date : " + today); 

    // Output : Today's Local date : 2014-01-14


    // -----------------------------------
    // 2. Get today's year, month, and day
    LocalDate today = LocalDate.now(); 
    int year = today.getYear(); 
    int month = today.getMonthValue(); 
    int day = today.getDayOfMonth(); 
    System.out.printf("Year : %d Month : %d day : %d \t %n", year, month, day); 

    // Output : Today's Local date : 2014-01-14 Year : 2014 Month : 1 day : 14 


    // -----------------------------------
    // 3. Get specific date
    LocalDate dateOfBirth = LocalDate.of(2010, 01, 14); 
    System.out.println("Your Date of birth is : " + dateOfBirth); 

    // Output : Your Date of birth is : 2010-01-14


    // -----------------------------------
    // 4. Get current time
    LocalTime time = LocalTime.now(); 
    System.out.println("local time now : " + time); 

    // Output : local time now : 16:33:33.369 // in hour, minutes, seconds, nano seconds


    // -----------------------------------
    // 5. Plus hours
    LocalTime time = LocalTime.now(); 
    LocalTime newTime = time.plusHours(2); // adding two hours 
    System.out.println("Time after 2 hours : " + newTime); 

    // Output : Time after 2 hours : 18:33:33.369


    // -----------------------------------
    // 6. Plus days
    LocalDate nextWeek = today.plus(1, ChronoUnit.WEEKS); 
    System.out.println("Today is : " + today); 
    System.out.println("Date after 1 week : " + nextWeek); 

    // Output: Today is : 2014-01-14 
    //		   Date after 1 week : 2014-01-21


    // -----------------------------------
    // 7. Plus and minus years
    LocalDate previousYear = today.minus(1, ChronoUnit.YEARS); 
    System.out.println("Date before 1 year : " + previousYear); 

    LocalDate nextYear = today.plus(1, YEARS); 
    System.out.println("Date after 1 year : " + nextYear); 

    // Output: Date before 1 year : 2013-01-14 
    //		   Date after 1 year : 2015-01-14


    // -----------------------------------
    // 8. Get ZonedDateTime
    ZoneId america = ZoneId.of("America/New_York"); 
    LocalDateTime localtDateAndTime = LocalDateTime.now(); 
    ZonedDateTime dateAndTimeInNewYork = ZonedDateTime.of(localtDateAndTime, america ); 

    System.out.println("Current date and time in a particular timezone : " + dateAndTimeInNewYork); 

    // Output : Current date and time in a particular timezone : 2014-01-14T16:33:33.373-05:00[America/New_York]
