public Order(){}
public Order(double price ,User user){
this.price=price;
this.user=user;
}

public int getId() {
return id;
}
private void setId(int id) {

}
public void setUser(User user){
this.user=user;
}
public User getUser(){

}

}

package com.zhuang;

private Set orders=new HashSet();

public User(String username,int password,Set orders){
