        hashSet.add("Dave");
        hashSet.add("Peter");
        hashSet.add("Phil");
        hashSet.add("Rohit");
        hashSet.add("Virat");

        System.out.println("hashSet : " + hashSet + "\n");

        /*
         * Removes the specified element from this set if it is present.
         */

        boolean isRemoved = hashSet.remove("Virat");
        System.out.println("isRemoved : " + isRemoved);
