public static void main(String[] args) {
AbstractList<Integer> myList = new ArrayList<Integer>();
myList.add(75);
myList.add(100);
myList.add(150);
myList.add(200);
myList.add(250);
myList.add(150);
myList.add(150);
myList.add(400);
System.out.println("Elements in the AbstractList = " + myList);
System.out.println("Last index of element 150 = "+ myList.lastIndexOf(150));
}
}Output
Elements in the AbstractList = [75, 100, 150, 200, 250, 150, 150, 400] Last index of element 150 = 6
