There was issue with mic so volume is low

[@NarenkumarMoorthyVisalatchi]

Solution: for (Iterator iterator = employeeList.iterator(); iterator.hasNext();){
Employee employee = iterator.next();
if (employee.getId()==id){
iterator.remove();
}
}

[@nprathyusha7876]

Here why using private

[@prasadkadu9737]

Private is always preferred
