Imagine we have a multifunctional device with printing, scanning and copying functions. The device should contain a bean of a scanner in it.
Java
@Component
public class Device {
private Scanner scanner;
// 1
public Device(Scanner scanner) {
this.scanner = scanner;
}
}// 2
public class Scanner {
// a constructor
}Kotlin
@Component
class Device /* 1 */ constructor(private val scanner: Scanner) {
}// 2
class Scanner {
// a constructor
}Write the annotations divided with a space and start them with @ symbol.
