around this issue As a general rule, it's more object-oriented to pass around objects that encapsulate concepts than passing around strings. That said, there are many cases (particularly when it comes to UI) when you need to translate sparse data (such as strings) to proper Domain Objects.
As an example, you need to translate user input in form of a string into an ISoda instance.

around this issue I'm attempting this question in preparation for a test. This is my best answer based on my understanding but I feel I may be missing something important. I think I have altered the responsibility of Navigator too much but I can't see a better way of doing it. , Could be better.
code :
public class Navigator {

  private final Route theRoute;
  private final MapView theMap;

  public Navigator(Route inRoute, MapView theMap) {
    theRoute = inRoute;
    this.theMap = theMap;
  }

  public void setup() {
    theRoute.calculateRoute();
  }

  public void display() {
    theMap.plot(theRoute);
  }

}

I hope this helps you . I have managed to figure out what the issue was -- it was caused by an erroneous semi-colon added to the 'Pebbles' array element in getProducts. After removing the semi-colon the application works fine.

Hope that helps Dependency injection in Angular2 relies on hierarchical injectors that are linked to the tree of components.
This means that you can configure providers at different levels:

around this issue Your MyPanel is not a @Component, therefore it's invisible to Spring and any @Autowired or other annotations won't be processed.
The key to Spring is to use it fully. Unless you know that something shouldn't be a bean (i.e. a domain class, entity or so on) it probably should be a bean.

around this issue Imagine you have a WebSite in which every user could put a code inside a box, then press "search" to find informations about a product. The code will match the pattern: SHOPNAME-PROGRESSIVENUMBER, for example: EVERYDAYSHOES-002, or NEWGAMES-005. , A solution I thought is:
