Question

List<Integer> list0 = new List1<Integer>();

a) Is the word “List” a keyword in java??

b) When creating an object, shouldn’t the name of the class be the same on both side? For example:

Point x = new Point(1,2)

c) What does the following code mean?

List<Integer> list0 = new List1<Integer>();

Answer 1

List1 must be declared somewhere as

public class List1<T> implements List<T> {
...

List is an interface, so objects of any class that implements List can be assigned to a variable of type List.
