You can use arraylist for this, or u can use other collection like Hashset
or Mapset but at this time its better that u should use Arraylist for
duplication you have to make ur own function at this time, on advance level
Java have such collection which stops duplication and which work on
key/value pairs.
ArrayList is dynamic and u can add elements in it on runtime.
ArrayList a = new ArrayList();
a.add("123");
int b = 3;
a.add(b);
similarly u can remove elements as well with remove method.
