Meaning of Java syntax: class A extends B

Question

What does this syntax mean in Java: class A extends B<C>? I came across this in an Android library and couldn't find it on google.

More specifically, this is what I had come across:

public class PullToRefreshExpandableListView extends PullToRefreshAdapterViewBase<ExpandableListView>

Look up Inheritance or read up on Object-oriented programming. This kind of question also does not fit StackOverflow. — mkobit, Sep 19 '14 at 07:33
It means that `A` extends a type-specialized version of the generic class `B`. A does not have an "is-a" relationship with B, but it has an "is-a" relationship with B. — Alexis King, Sep 19 '14 at 07:33

Generics with Class and Interfaces Genrics is one of the core feature of Java programming and it was introduced in Java 5. We can define our own classes and interfaces with generics type.

A generic type is a class or interface that is parameterized over types. We use angle brackets (<>) to specify the type parameter.
