        this.nation=nation;
        this.province=province;

    public void print(){
        System.out.println("地址資訊為："+this.nation+this.province+this.city+this.street+" "+"郵政編號："+this.code);
    }
}

public class AddressTest{
    public static void main(String args[]){
        Address a=new Address("中國","廣東省","東莞市"
 
,"松山湖114號","522101");
        a.print();
