要打印一个hashmap，其中key是员工编号，值是arraylist

    Employee e = new Employee();
    String eno=e.getEno();
    HashMap<String,ArrayList<Employee>> map = new HashMap<String,ArrayList<Employee>>();
    ArrayList<Employee> al = new ArrayList<Employee>();
    Employee e1=new Employee("1001","Rahul", "Gupta", "agupta");
    Employee e2=new Employee("1002","Bijay", "Gupta", "bjay");
    al.add(e1);
    al.add(e2);
    map.put(eno, al);
    for (Map.Entry<String, ArrayList<Employee>> entry : map.entrySet()) {

        String key = entry.getKey();

        ArrayList<Employee> values = entry.getValue();

        System.out.println("Key = " + key);

        System.out.println("Values = " + values + "n");

    }       
    Employee e = new Employee();
    String eno
