找不到Java符号？

Question

我正在为我的java类做一个项目，我无法理解为什么我收到此错误。这是我的代码：

public class address 
{ 
String Street;
String City;
String State;
String Zip;

public address()
{
Street = "";
City = "";
State = "";
Zip = "";
}

public void setStreet(String street)
{
Street = street;
}

public void setCity(String city)
{
City = city;
}

public void setState(String state)
{
State = state;
}

public void setZip(String zip)
{
Zip = zip;
}

public String getStreet()
{
retrun Street;
}

public String getCity()
{
return City;
}

public String getState()
{
return State;
}

public String getZip()
{
return Zip;
}


}

这是我每个员工的地址等级。我们刚刚了解了OOP。这是带有错误的CMD输出：

Answer 1

错字：

public String getStreet()  {
    retrun Street; // should be return
}

Answer 2

retrun拼写错误。

Answer 3

您有拼写错误。你在getStreet方法中写了'retrun'而不是'return'。

Answer 4

我会尝试使用您的IDE生成这种代码。自己打字只会导致拼写错误。

// type two lines
public class Address {
    private String street, city, state, zip;

    // and use the IDE to generate a constructor
    public Address(String street, String city, String state, String zip) {
        this.street = street;
        this.city = city;
        this.state = state;
        this.zip = zip;
    }

    // generate getters and setters
    public String getStreet() {
        return street;
    }

    public void setStreet(String street) {
        this.street = street;
    }

    public String getCity() {
        return city;
    }

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

    public String getState() {
        return state;
    }

    public void setState(String state) {
        this.state = state;
    }

    public String getZip() {
        return zip;
    }

    public void setZip(String zip) {
        this.zip = zip;
    }
}

Answer 5

你拼错了return

public String getStreet()  {
    retrun Street; // wrong
}

一定是

public String getStreet()  {
    return Street; // correct
}
