if(search.length() == 0){
displayData(studentList);
} else {
search = ".*" + search + ".*";
Vector<Student> studentListCopy= (Vector<Student>)studentList.clone();
for(int i = 0; i < studentListCopy.size();i++){
if (!studentListCopy.elementAt(i).getFirstname().toLowerCase().matches(search.toLowerCase()))
if(!studentListCopy.elementAt(i).getLastName().toLowerCase().matches(search.toLowerCase())) {
studentListCopy.remove(i);
}
}
displayData(studentListCopy);
}
}
