1) An anonymous inner class is an object which is a class like an object which can represent any class.
It can be created using the 2 methods like the abstract or concrete. And with the help of the interface.
2) List<Integer> is not a subclass of List<Number> hence one would mostly use the ArrayList as that is a subclass.

D Question 12 1.5 pts Check the true statements about NumPy arrays: O A single instantiated NumPy array can store multiple types (e.g., ints and strings) in its individual element positions. A NumPy array object can be instantiated using multiple types (e.g., ints and strings) in the list passed to its constructor O Memory freeing will require a double-nested loop. The number of bits used to store a particular NumPy array object is fixed. O The numpy.append(my.array, new_list) operation mutates...

Question 1) Consider a class Point that models a 2-D point with x and y coordinates. Define the class point that should have the following Private data members x and y (of type int), with default values of 0 A constant ID of type int A private static integer data member named numOfPoints This data member should be o Incremented whenever a new point object is created. o Decremented whenever a point object is destructed. A default constructor An...
