LocalDate to Instant

In order to convert it to an instant you need to have a LocalDateTime instance

• Java Instant class is used to represent a specific moment on the time line. This might be used to record event time-stamps in the application.
• java.util.Date represents an instant on the time-line, not a date. The actual data stored within the object is a long count of milliseconds since 1970-01-01T00:00Z.
• The equivalent class to java.util.Date in JSR-310 is Instant, thus there is a convenient method toInstant() to provide the conversion.

			
					public Instant toInstant()

			
	

			
	
			

		
	

• Converts this Date object to an Instant.
• The conversion creates an Instant that represents the same point on the time-line as this Date.
• Returns an instant representing the same point on the time-line as this Date object.

Date to LocalDate

			
					LocalDate date = LocalDate.now();
Instant instant = date.atStartOfDay(ZoneId.systemDefault()).toInstant();

			
	

			
	
			

		
	

			
					Date input = new Date();
Instant instant = input.toInstant();
ZonedDateTime zdt = instant.atZone(ZoneId.systemDefault());
LocalDate date = zdt.toLocalDate();
