Creating an array to store generic types in Java [duplicate]

Answer 1

Question 1.

Well, it's not the correct syntax. Hence that does not work.

Question 2.

ArrayList[] pl2 = new ArrayList[10];
ArrayList[] pl3 = new ArrayList[10];

Since pl2 is defined with generic type at compile time, the compiler will be know that pl2 is only allowed to have Integers and if you try to assign somthing other than Integers you will be alerted and compilation will fail.

In pl3 since there is no generic type you can assign any type of object to the list.
