<> instead of ()

[adam2016]

hello people I've recently been studying the stl library and I noticed a lot of the classes in the stl library take <> instead of ()

for example when I'm creating a normal class with a constructor it would be

  aclass aclassObject("hello",23);

but when creating objects from a lot of the STL classes they contain <> instead of ()

  Vector<int i> vec;

I'm just wondering why this is? and how would I even create a class with <> instead of ().

It's a class template.
