I assume that you meant that you don't want to implement "Comparable" interface in your class. Use Comparator and Collection's sort static method:

import java.util.*;
public class EmpSort {
    static final Comparator SENIORITY_ORDER =
                                 new Comparator() {
        public int compare(Employee e1, Employee e2) {
            return e2.hireDate().compareTo(e1.hireDate());
        }
    };

    // Employee database
    static final Collection employees = ... ;

    public static void main(String[] args) {
        Liste = new ArrayList(employees);
        Collections.sort(e, SENIORITY_ORDER);
        System.out.println(e);
    }
}
