Consider this Angular service and component:

import { Injectable } from '@angular/core';
@Injectable({providedIn: 'root'})
export class MessageService {
  getMessage() { return 'Hello'; }
}
@Component({selector: 'app-sample', template: ''})
export class SampleComponent {
  constructor(private msgService: MessageService) {

}

What will be printed in the console when SampleComponent is instantiated?
