doubt regarding <type parameter>

[subith86]

I am familiar with Objects as type parameters, for example
ArrayList<String, Integer>
TreeSet<Object>

But now I encountered a code like shown below

interface Dog<E extends Animal>

What does <E extends Animal> type means? Is the type having properties of both E and Animal as in the case of normal inhertiance?

[Petr]

It is generic. It mean that you can use a all class, which extends Animal. and it all.

[subith86]

you can use a all class, which extends Animal

Is it ALL classes which extends Animal or Class E and Animal alone?

[Petr]

)) So. How you think what is class E?

Try the generics tutorial.

Thanks Troll,

I was confused with E. Even when I googled generics I could see lot of "E"s.;)
I'll make this thread SOLVED.
