In this test, we will look at a data structure for representing fruit trees in an orchard. The overall interface for these trees is here: interface Tree f int sizeO: // total number of fruit in the tree Tree grow(int factor): // grows the number of fruit by given factor void harvest (Collection bag): // harvests (adds) all fruits in this tree into bag a) 1 First, complete the following class for representing individual fruit in the t ee. abstract class Fruit implements Tree eoverride public int sizeO I/ write this method below eoverride public Tree grow (final int factor) TODo in 2d) below, not here /) eoverride public void harvest (final Collection bag) I/ write this method below We also need a few concrete kinds of fruit: class Mango extends Fruit (/intentionally left empty /) class Peach extends Fruit (/* intentionally left empty */)
