I'm trying to write a program for a college class and I'm supposed to use four ArrayLists to store random numbers, but I keep getting an error when I first try to create the ArrayLists. This is what I typed:
ArrayList<Integer> list1, list2, list3, list4;
list1 = new ArrayList<Integer>();
list2 = new ArrayList<Integer>();
list3 = new ArrayList<Integer>();
list4 = new ArrayList<Integer>();
And I get the error: "type ArrayList does not take parameters".
How do I fix this? Is there any way to shorten this?
ArrayList<Integer> list1, list2, list3, list4;
list1 = new ArrayList<Integer>();
list2 = new ArrayList<Integer>();
list3 = new ArrayList<Integer>();
list4 = new ArrayList<Integer>();
And I get the error: "type ArrayList does not take parameters".
