issue in adding common elements of arraylist in third arraylist using for loop

I am trying to compare two ArrayLists, and after comparision i have to get common elements between those two arraylists and show them in a third arraylist. This is my code, here newList is the arraylist in which i want to add the common elements but each time i am adding elements in this arraylist it is showing only the last element. ``` ArrayList<String> list2 = new ArrayList<String>(); list2.add("1"); list2.add("abc"); list2.add("3"); list2.add("4"); ArrayList<String> list1 = new ArrayList<String>(); list1.add("3"); list1.add("4"); list1.add("7"); list1.add("8"); list1.add("12"); list1.add("4"); list1.add("53"); list1.add("2"); list1.add("62"); list1.add("abc"); System.out.println("btn click r_answer "+list1+" "+list2); for (int i=0;i<list1.size();i++) { for (int j=0;j<list2.size(); j++) { if(list1.get(i).equals(list2.get(j))) System.out.println("equals..:"+list2.get(j)); newList.add(list2.get(j)); } } ```
