Array list integer not working

Question

i am trying to make an ArrayList of type integer, but it gives me this error(I am using this compiler called jikes) Code:

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

Error:

***Semantic error: using type arguments to access generic types requires the use of "-source 1.5"'or greater. Compilation will continue to use the raw type "Java.util.arraylist", but no class file will be emitted.

Every variable needs a name, so give "him" one: `ArrayList list = new ArrayList();`. And your compiler level is most likely `1.4`. You need at least `1.5` to use generics. Read the manual/help page of your compiler to find out how to do that. — Tom, Feb 24 '15 at 19:41

Your arraylist has no name:

ArrayList<Integer> name = new ArrayList<>();

Please can you explain why - code only answers usually require an explanation. – ThePerson Feb 24 '15 at 19:48
Because you never named the variable. – Araymer Feb 24 '15 at 19:59
I just noticed that... Whoops. Ignore me. – Araymer Feb 24 '15 at 20:10
@Araymer No problem. You can delete your own comments if you like. – Tom Feb 24 '15 at 20:28

Correct initialization should be

ArrayList<Integer> X = new ArrayList<Integer>();

you need to assign variable
