Bad operator Error occurs on > operator

Question

 if ((list.get(i)) > (list.get(maxInd))) {
     maxInd = i;
 }

error giving in on operator, where list is an object of LinkedList and MaxInd contains the first element of linked list while i is the variable of for loop

  LinkedList list = new LinkedList();
    list.add(2);
    list.add(1);
    list.add(3);

    int maxInd = 0;
    int list_size = list.size();
    for (int i = 0; i < list_size; i++) {
        if((list.get(i)) > (list.get(MaxInd))) {
            maxInd = i;
        } // end if condition    
    } // end for loop

Can you show all the code, in particular how you declare the linked list? — assylias, Aug 31 '15 at 15:09
What type of object are you storing on the list? If It is a custom class, you have to overload the operator — Rumpelstinsk, Aug 31 '15 at 15:11

The issue is that your LinkedList uses a raw type, meaning that the elements of the list are treated as Object types. The simplest solution is to use a type parameter:

LinkedList<Integer> list = new LinkedList<Integer>();
// ...

Or you can use a cast, but only only if you're sure that all the elements in the list are Integers:

if ((Integer)(list.get(i)) > (Integer)(list.get(MaxInd))) {
    MaxInd = i;
}
