4. throw - can use to throw exception explicitly, throws - used to propagate the exception
6. Iterate the List and add into Set(HashSet) to remove the duplicates
10.@Override
	public int compareTo(Object o) {
		// TODO Auto-generated method stub
		ComparableSorting e = (ComparableSorting) o;
		if(this.employee_id > e.employee_id){
			return 1;
		}else{
			return -1;
		}
