What is the purpose of "<>" in java?

Question

I'm confused about this symbol.
Is it used to define only data types of Lists?

Answer 1

When instantiating a generic type such as a List, Set or Map, this is used to specify what actual type is stored in that particular instance.
e.g. ArrayList<String> is a list of String.
<> is used when the type definition is not needed,or known implicitly e.g.
Entry<String, String> myEntry = new Entry<>("FirstItem", "A");

Answer 2

Naveen Deenadayalan well, yes, and ArrayList implements List.
Furthermore, that's right, it is not only used for List, it is useful for any generics type. You can even create your own class with generics.

Answer 3
