Question

c) 1.5 Now, complete this s class for representing multiples of the same subtree in a compact way makes its child (subtree) appear howmany times for the purpose size and harvest. The size of each Cluster node is the actual size of the representing Concretely, a Cluster node of the operati node's child times the multiplier; for exa ons mple, Cluster (5, Branch (Mango, Peach)) has size 10 class Cluster implements τ ree ( public Cluster (Final int howmony, final Tree child this. howmany howmany: this. child -child; private final int howmany: private final Tree child: public int getMultiplierO return howmany: public Tree getChildo (return child: eOverride public int size。 { // write this method below eOverride public Tree grow(final int factor) // vrite this method below // growth occurs here!! use a suitable nex multiplier in the resul t eoverride public void harvest (tinal Collection Fruit) bag) I write this method below

Answer 1

class Cluster implements Tree {

    public Cluster(final int howmany, final Tree child) {
        this.howmany = howmany;
        this.child = child;
    }

    private final int howmany;
    private final Tree child;

    @Override
    public int size() {
        return child.size() * howmany;
    }

    @Override
    public Tree grow(int factor) {
        return child.grow(factor);
    }

    @Override
    public void harvest(Collection<Fruit> bag) {
        child.harvest(bag);
    }
}
