import groovy.util.logging.*
import java.util.logging.Level

@Log("log2")
class Car {
    Car() {
        log2.setLevel(Level.FINE)
        log2.severe 'Car constructed'
        log2.warning 'Car constructed'
        log2.info 'Car constructed'
        log2.config 'Car constructed'
        log2.fine 'Car constructed'
        log2.finer 'Car constructed'
        log2.finest 'Car constructed'
    }
