Suppose that you are writing a Spring application and need to declare a class that requires a predefined object of the Random class as a dependency. Select what to put instead of each (N) to make it work.
Java
// (1)
public class RandomBasedComponent {
private final Random random;
// (2)
public RandomBasedComponent(Random random) {
this.random = random;
}
// (3)
public void performAction() {
// do something with random
System.out.println(random.nextInt());
}
}
// (4)
class RandomConfig {
private static final long RANDOM_SEED = 1000L;
// (5)
public Random predefinedRandom() {
return new Random(RANDOM_SEED);
}
}Kotlin
// (1)
class RandomBasedComponent /* (2) */ constructor(private val random: Random) {
// (3)
fun performAction() {
// do something with random
println(random.nextInt())
}
}
// (4)
class RandomConfig {
companion object {
private const val RANDOM_SEED = 1000L
}
// (5)
fun predefinedRandom(): Random {
return Random(RANDOM_SEED)
}
}
