Cоmplete the cоde fоr а generic clаss Storаge that only accepts objects that extend the abstract class TransportUnit. You don't need to write the existing code. Just write the missing codes. You need to implement Storage extending TransportUnit and add a method compareCapacity() that compares the capacity of the two stored units and prints which one is larger or if they are equal. //Sample output Truck T112 has larger capacity.Ship Poseidon has larger capacity. // code starts hereabstract class TransportUnit { double capacity; public TransportUnit(double capacity) { this.capacity = capacity; } abstract String getUnitType();}// Subclassesclass Truck extends TransportUnit { String truckId; public Truck(String truckId, double capacity) { super(capacity); this.truckId = truckId; } @Override String getUnitType() { return "Truck " + truckId; }}class Ship extends TransportUnit { String shipName; public Ship(String shipName, double capacity) { super(capacity); this.shipName = shipName; } @Override String getUnitType() { return "Ship " + shipName; }}// Generic Storage class. Fill in the dashes and complete codeclass Storage { private _____ unit1; private _____ unit2; public Storage(_____ unit1, _____ unit2) { this.unit1 = unit1; this.unit2 = unit2; } public void compareCapacity() { // Complete this method }}// Main methodclass Testmain { public static void main(String[] args) { //Write code in this method to compare 2 trucks and 2 ships. Also, fill in the dashes for Storage and call comparecapacity() method // Compare two trucks Storage truckStorage = new Storage(t1, t2); // Compare two ships Storage shipStorage = new Storage(s1, s2); }}
