}
public void setName(String name) {
this.name = name;
}
public String sayHello() {

public Map<String, User> getUsers() {
return users;
}
public void setUsers(Map<String, User> users) {
this.users = users;
}
public Map<String, Collection> getList() {
return list;
}
public void setList(Map<String, Collection> list) {
this.list = list;
}
