Creating an array problem. help please

Question

Dupe: http://stackoverflow.com/questions/185594/java-generics-syntax-for-arrays

I want to create an array that will hold linked lists of Integer type..

import java.util.LinkedList;

public class Test {

    public static void main(String [] args){

     LinkedList<Integer> [] buckets = new LinkedList<Integer>[10];  

    }
}

I get an error saying: Cannot create a generic array of LinkedList

Why is this? Can it be solved?

Answer 1

Generics and ye olde arrays don't get on well (this subject has been done to death meny times, here and elsewhere). Use an (array) list of lists.

Answer 2

You could wrap it with another list type, e.g:

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

Answer 3

try

List<Integer> [] buckets = new LinkedList[10];

I don't know why Java doesn't allow generics on arrays given you can just drop the generic on the right (though it will give an unchecked warning this way)
