Class relationships: Correct Solution


Consider the follow class declarations:

public class Enec {
    public Mahe getOnnas() {
        ...
    }

    public File getPiis() {
        ...
    }
}

public class Mahe extends Splapui {
    public List<Siui> getOcVis() {
        ...
    }
}

public class Siui {
    public byte[] getPreal() {
        ...
    }

    public List<String> getJode() {
        ...
    }
}

public class Splapui {
    public File getEnt() {
        ...
    }
}
  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!

    Solution

  2. Given the following variable:

    Enec ne

    ...and the following method:

    public void process(List<String> item)

    ...write code to process the jode of the first ocVi of ne.

    Solution

    for (Siui ocVi : ne.getOnnas().getOcVisList()) {
        process(ocVi.getJode());
    }
