public void removeDuplicateDataFromArrayList(){
ArrayList<String> al = new ArrayList<>();
al.add("a");
al.add("b");
al.add("c");
al.add("c");
al.add("a");
HashSet<String> hs = new HashSet<>();
hs.addAll(al);
al.clear();
al.addAll(hs);
System.out.println("The ArrayList values are :"+ al);
// Or
System.out.println("ArrayList : ");
for (Object data : al) {
System.out.println(data);
}
