doubt in IS-A relationship

[Parameswaran Thangavel]

hi
i doubt how this statisfies the IS-A relation

public class Species { }
public class Animal {private Species species;}

the class Animal has a reference to the class species....

literally is-a means extends....

can any one clear me?
Thanks in advance.

Yeah u right,
The question doesnt satisfy IS-A relationship.
IS-A means having extends relationship with the class

class Vehical {

}

class Car extends Vehical {

}

whenever you are extending any class then it is always a is-a relationship and whenever you were actually using a particular class in other class or you has the class(Species) in the class(Animal) the you are in has a relationship.
