So is the difference between inheritance and composition is that of a fridge and iceman?

class Man {
fun greet(){return "hi"}
}

class IceMan extends Man{
override fun greet(){return "hi i am iceman"}
fun getIce(){return "ice"*Random.nextInt()}
}

class Fridge{
private Man manAi;
private String s = "ice";
fun greet(){return manAi.greet()}
fun getIce(){return s*Random.nextInt()}
}

}

=========
Basically , in first case, a class is getting features by inheriting from parent while in another case, a class is getting features by internally having objects of other classes that could provide those features?
