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;
}
}
最佳答案
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()
关于java - 返回包含多个变量的字符串的方法，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/10019745/
