Strange compilation error. Works fine in IntelliJ.

  • 0

    Why the compiler always complain about the following code "IllegalArguments"? It just compiles in IntelliJ.

    PriorityQueue<ListNode> pq = new PriorityQueue<ListNode>(lists.length,new Comparator<ListNode>(){
                public int compare(ListNode a, ListNode b) {
                    return a.val - b.val;
