用java实现一个枚举类，有两个属性，编号和各省份地级市

public enum City {
BEIJING(1, "北京市"),
TIANJIN(2, "天津市"),
SHANGHAI(3, "上海市"),
CHONGQING(4, "重庆市"),
SHENZHEN(5, "深圳市"),
GUANGZHOU(6, "广州市"),
HANGZHOU(7, "杭州市");

private int id;
private String name;

private City(int id, String name) {
this.id = id;
this.name = name;
}

public int getId() {
return id;
}

public String getName() {
return name;
}

public static City findByCode(int code) {
for (City city : values()) {
if (city.id == code) {
return city;
}
}
return null;
}
}
