Hello. Im new here. I have a question:
I have this copy constructor here:
/** Copy Constructor.
* Since landscape is immutable in the scope of our project, you could
* do a simple reference copy for it.
* However, Fish and Plants are mutable, so those lists must be copied
* with a DEEP copy!
* (In other words, each fish and each plant must be copied.)
*/
public Model(Model other) {
landscape = other.landscape;
fish = new ArrayList<Fish>();
for (Fish f : other.fish) {
fish.add(new Fish(f));
}
plants = new ArrayList<Plant>();
for (Plant p : other.plants){
plants.add(new Plant(p));
}
}
I want to ask how do I implement this:
/** Returns a COPY of the plants list. Hint: Use the ArrayList<Plant>
* copy constructor, or you will fail our tests! */
public ArrayList<Plant> getPlants() {
//HOW DO I COPY the plants list
}
Thank you for your help.
