State whether each of the following is true or false. If false, explain why.

a) To determine the difference between two Instants, use class Duration’s static method difference, which returns a Duration object containing the time difference.

b) Streams are easy to parallelize, enabling programs to benefit from enhanced perfor- mance on multi-core systems.

c) Interface Supplier, like interface Callable, is a functional interface with a single meth- od that receives no arguments and returns a result.

d) CompletableFuture static method runAsync asynchronously executes a Supplier task that returns a value.

e) CompletableFuture static method supplyAsync asynchronously executes a Runnable task that does not return a result.
