I'm using the following package: https://docs.oracle.com/javase/8/docs/api/java/time/package-summary.html
How do I create a clock variable? I tried:
Clock clock = new Clock();
But I got the error:
TimeCheck.java:14: error: Clock is abstract; cannot be instantiated
I also tried private Clock clock; outside of the main() function, but when I ran the main() function and tried clock.instant() it said:
TimeCheck.java:16: error: non-static variable clock cannot be referenced from a static context
The java.time classes automatically use a default Clock object.
Instant now = Instant.now() ; // Default `Clock` used implicitly.
You only need to obtain a Clock if you want altered behavior. Typically that would be for testing or demonstration.
The java.time framework eschews the use of new. Look for factory methods instead.
Look at the static methods on the Clock class. You will find methods to give you various clocks with altered cadence, or fixed to a specific moment, or continually operating with a delay.
Clock fixedClock = Clock.fixed( Instant.EPOCH , ZoneId.of( "Asia/Kolkata" ) ) ;
Instant nowFake = Instant.now( fixedClock ) ;
