UML Class Diagram (Java Related) Difference Between Dotted and Dashed Lines

Question

Are there a difference between these two associations? I want to create Java Program with this.

If there is a difference between those two, What are they? Any example codes are highly appreciated.

Thanks for your time, Cheers

Is just a dependency. This Board Interface does not have Piece enum as a part of the class but works with it.

For example: enum Piece{GREEN, BLUE}, and

class BoardFactory {

  Board create(Piece piece) {
    if(piece == Piece.GREEN) {
      return new GreenBoard();
    }
  }

}

This one is even more simple. It is a realization of the interface. BoardController implements BoardUI
