java - 返回包含多个变量的字符串的方法

Question

这是我编写的一个保存地址信息的构造函数，但我在最后部分遇到了麻烦，我必须返回一个保存名称、地址、城市、州邮政编码的字符串。正确的写法是什么？

公开课地址{

private String name;
private String address;
private String state;
private String city;
private String zipcode;

public Address(String name, String address, String state, String city, String zipcode){

    this.name = name;
    this.address = address;
    this.state = state;
    this.city = city;
    this.zipcode = zipcode;


}

public Address(){

    name = "occupant";
    address = " ";
    state = " ";
    city = " ";
    zipcode = " ";


}

public void setAddress(String Address){

    this.address = Address;

}

public void setstate(String state){

    this.state= state;


}

public void setcity(String city){

    this.city = city;
}

public void setzipcode(String code){

   this.zipcode = code; 

}

public String getaddress(){  // Return string that contains name and address and city and zipcode

    return getaddress() + " " + return state + " " + return city + " " + return code;



}

}

Answer 1

 return address + " " + state + " " + city + " " + code;

一些注意事项:

• 只有一个返回，后跟要返回的对象，这是字符串连接的结果
• 调用连接方法 getFullAddress() 以将其与 getter 区分开来。
• 使用小写变量名
• getter 和 setter 应该采用驼峰式大小写:setCity()、getState()
