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<Integer> list = new ArrayList<Integer>();. 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. Commented Feb 24, 2015 at 19:41

  • Looking a jikes: any good reason you are using just that? Commented Feb 24, 2015 at 19:47
  • @Tom: Make that an answer. Because it is. Commented Feb 24, 2015 at 20:29

Your arraylist has no name:

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

Please can you explain why - code only answers usually require an explanation.
Because you never named the variable.
I just noticed that... Whoops. Ignore me.
@Araymer No problem. You can delete your own comments if you like.

Correct initialization should be 

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

you need to assign variable
