About Question enthuware.ocpjp.v7.2.1270 :

[kashyapa]

Why

Code: Select all

ArrayList<> list = new ArrayList<>();

does not work?

i tried out it, but it says;

java.lang.RuntimeException: Uncompilable source code - illegal start of type

The whole point of generifying a class such as ArrayList is to specify what kind of objects will be stored/retrieved from it! What do you think you declaration means to the compiler?

Code: Select all

List<String> list = new ArrayList<>(); 
list.add("A");

The explanation says that this wont compile?
