用java语言编写：设计实现地址概念的类addresss.

直接用对应属性的get/set方法不可以吗？
自动添加！添加步骤你应该会吧！

这样的问题建议你自己写下，找下感觉
初学着就是写这种意思很明确的类，来感觉java类的概念

大体就跟上面的一样 拷过去旧能用了

public class Address {
private String province;
private String city;
private String houseNumber;
private String postCode;

public String getProvince() {
return province;
}

public void setProvince(String province) {
this.province = province;
}

public String getCity() {
return city;
}

public void setCity(String city) {
this.city = city;
}

public String getHouseNumber() {
return houseNumber;
}

public void setHouseNumber(String houseNumber) {
this.houseNumber = houseNumber;
}

public String getPostCode() {
return postCode;
}

public void setPostCode(String postCode) {
this.postCode = postCode;
}

}
