Java New Date Time API Example

 LocalDate represents only a date.
 LocalTime represents only a time.
 LocalDateTime class represents both date and time.
 Instant represents timestamp.

// to increase date by plus 1

// to increase month by plus 1

// to increase year by plus 1

//to increase date day and year all by plus 1
LocalDate next = LocalDate.now().plusDays(1).plusMonths(1).plusYears(1);

//to get only current year

//to get only current month
Month currentMonth = LocalDate.now().getMonth();

//to get only current date

System.out.println("TODAY DATE\t:"+currentDate);

//to get only current week day

//to check weather current or any year is leap year or not

//to check manually any year is leap or not

System.out.println("---------------------------------\nWORKING WITH TIME\n---------------------------------");
// to know current time only without date

System.out.println("CURRENT TIME\t:"+currentTime);

// to know current hour from current time

System.out.println("CURRENT HOUR\t:"+currentHour);

// to know current minute from current time
int currentMinute = LocalTime.now().getMinute();

// to know current second from current time

// to know current second from current time
int currentMillisecond = LocalTime.now().getNano();

System.out.println("---------------------------------\nWORKING WITH DATE & TIME\n---------------------------------");

// to know current date and time
LocalDateTime dateTime = LocalDateTime.now();

// to work with timestamp
