Class relationships: Correct Solution


Consider the follow class declarations:

public class Drasvec {
    public String getDri() {
        ...
    }
}

public class Ench extends Drasvec {
    public Genwhe getSeang() {
        ...
    }
}

public class Genwhe {
    public int getBir() {
        ...
    }

    public List<RisNetas> getVapas() {
        ...
    }
}

public class RisNetas {
    public File getIosm() {
        ...
    }

    public int getIrier() {
        ...
    }
}
  1. Draw a diagram showing the class relationships.

    You only need to diagram the classes listed above. You only need to show the name of each class; do not show their methods or properties.

    Draw arrows between the classes that have relationships, and label each arrow with one of the following:

    Make sure your arrows point in the correct direction!
