How to sort the name- comparator issue? please read description fully

Question

I have a object

Class Employee(id, name, city){ };

List<Employee> list1 = new ArrayList();
list1.add(new Employee(2, "Abc", "eJ"));
list1.add(new Employee(3, "Zec", "eJ");
list1.add(new Employee(4, "Cec", "eJ"));
list1.add(new Employee(5, "Abc", "Ab"));
list1.add(new Employee(6, "Abc", "Ze"));

i need to sort Employee object based on name even along with city

"Abc","Ab" 
"Abc","eJ"
"Abc","Ze"
"Cec","eJ"
"Zec", "eJ"

but i am getting sorting like - city not getting ordered along with name.

"Abc","eJ" - city not ordered here
"Abc","Ab"
"Abc","Ze"
"Cec","eJ"
"Zec", "eJ"

Anyone knows, plz help me wat is the issue with comparator?
