I have been trying to access the elements of several arrays that are held within an array list. I am able to access it regularly, but the problem comes when I use generic type E to account for different data types. This gives me a class cast exception. If I change the type of tempStart and tempScan and corresponding casts to int[] (since that is what I am using to pass in) it runs.
public static <E> ArrayList<E> removeDuplicates(ArrayList<E> list) {
if (list.get(0).getClass().isArray()) {
System.out.println(" I am an array!");
//go through the arrays and make sure they are
//not the same, remove any that are the same
//make flag to see if something is different
boolean matching;
for (int idx = 0; idx < list.size() - 1; idx++) {
E[] tempStart =(E[])list.get(idx);
for (int k = idx + 1; k < list.size(); k++) {
matching = true;
E[] tempScan = (E[])list.get(k);
for (int index = 0; index < tempStart.length; index++) {
if (tempStart[index] != tempScan[index]) {
matching = false;
}
}
if (matching) {
list.remove(tempScan);
k--;
}
}
}
