Question

Answer 1

The constructors of both Stopwatch and Logger are private. You need to use factory methods to instantiate them.

In case of the Stopwatch, you could use the createUnstarted() method:

val stopwatch = Stopwatch.createUnstarted()

In case of Logger, you must use the apply method. However, it requires an underlying SLF4J logger. You can create one through SLF4J's LoggerFactory:

import org.slf4j.LoggerFactory
val logger = Logger(LoggerFactory.getLogger(getClass))
