Java接口通过调用同一接口访问不同的类

我想以一种方式使用java接口，在我的另一个类中调用定义接口的方法，如“private SoapURL SoapURL；”并且，我可以访问任何类的方法，例如：我想使用登录：-

private SoapURL soapURL;
SoapUrl = LoginSoap ();

String nameSpace = soapURL.getMethodName();
String url = soapURL.getUrl();

有没有办法做这样的事。很抱歉，我对面向对象的原则不是很在行，但如果我的问题有解决方案，我想知道。提前谢谢

public interface SoapURL {
    public String getNameSpace();
    public String getUrl();
    public String getSoapAction();
    public String getMethodName();
    public String getTag();
}

登录OAP类

public class LoginSoap implements SoapURL {

    @Override
    public String getNameSpace() {
        return "https://host.com/MobileWFC/";
    }

    @Override
    public String getUrl() {
        return "https://host.com/MobileWFC/MobileWS.asmx";
    }

    @Override
    public String getSoapAction() {
        return "https://host.com/MobileWFC/UserControl";
    }

    @Override
    public String getMethodName() {
        return "UserControl";
    }

    @Override
    public String getTag() {
        return "Login Activity";
    }
}

public class SignUpSoap implements SoapURL {

    @Override
    public String getNameSpace() {
        return "https://host.com/MobileWFC/";
    }

    @Override
    public String getUrl() {
        return "https://host.com/MobileWFC/MobileWS.asmx";
    }

    @Override
    public String getSoapAction() {
        return "https://host.com/MobileWFC/UserRegister";
    }

    @Override
    public String getMethodName() {
        return "UserRegister";
    }

    @Override
    public String getTag() {
        return "SignUp Activity";
    }
}

public class ResetPasswordSoap implements SoapURL {

    @Override
    public String getNameSpace() {
        return "https://host.com/MobileWFC/";
    }

    @Override
    public String getUrl() {
        return "https://host.com/MobileWFC/MobileWS.asmx";
    }

    @Override
    public String getSoapAction() {
        return "https://host.com/MobileWFC/UserPasswordReset";
    }

    @Override
    public String getMethodName() {
        return "UserPasswordReset";
    }

    @Override
    public String getTag() {
        return "Forget Password Activity";
    }
}

SignUpSoap类

public class LoginSoap implements SoapURL {

    @Override
    public String getNameSpace() {
        return "https://host.com/MobileWFC/";
    }

    @Override
    public String getUrl() {
        return "https://host.com/MobileWFC/MobileWS.asmx";
    }

    @Override
    public String getSoapAction() {
        return "https://host.com/MobileWFC/UserControl";
    }

    @Override
    public String getMethodName() {
        return "UserControl";
    }

    @Override
    public String getTag() {
        return "Login Activity";
    }
}

public class SignUpSoap implements SoapURL {

    @Override
    public String getNameSpace() {
        return "https://host.com/MobileWFC/";
    }

    @Override
    public String getUrl() {
        return "https://host.com/MobileWFC/MobileWS.asmx";
    }

    @Override
    public String getSoapAction() {
        return "https://host.com/MobileWFC/UserRegister";
    }

    @Override
    public String getMethodName() {
        return "UserRegister";
    }

    @Override
    public String getTag() {
        return "SignUp Activity";
    }
}

public class ResetPasswordSoap implements SoapURL {

    @Override
    public String getNameSpace() {
        return "https://host.com/MobileWFC/";
    }

    @Override
    public String getUrl() {
        return "https://host.com/MobileWFC/MobileWS.asmx";
    }

    @Override
    public String getSoapAction() {
        return "https://host.com/MobileWFC/UserPasswordReset";
    }

    @Override
    public String getMethodName() {
        return "UserPasswordReset";
    }

    @Override
    public String getTag() {
        return "Forget Password Activity";
    }
}

重置密码SOAP类

public class LoginSoap implements SoapURL {

    @Override
    public String getNameSpace() {
        return "https://host.com/MobileWFC/";
    }

    @Override
    public String getUrl() {
        return "https://host.com/MobileWFC/MobileWS.asmx";
    }

    @Override
    public String getSoapAction() {
        return "https://host.com/MobileWFC/UserControl";
    }

    @Override
    public String getMethodName() {
        return "UserControl";
    }

    @Override
    public String getTag() {
        return "Login Activity";
    }
}

public class SignUpSoap implements SoapURL {

    @Override
    public String getNameSpace() {
        return "https://host.com/MobileWFC/";
    }

    @Override
    public String getUrl() {
        return "https://host.com/MobileWFC/MobileWS.asmx";
    }

    @Override
    public String getSoapAction() {
        return "https://host.com/MobileWFC/UserRegister";
    }

    @Override
    public String getMethodName() {
        return "UserRegister";
    }

    @Override
    public String getTag() {
        return "SignUp Activity";
    }
}

public class ResetPasswordSoap implements SoapURL {

    @Override
    public String getNameSpace() {
        return "https://host.com/MobileWFC/";
    }

    @Override
    public String getUrl() {
        return "https://host.com/MobileWFC/MobileWS.asmx";
    }

    @Override
    public String getSoapAction() {
        return "https://host.com/MobileWFC/UserPasswordReset";
    }

    @Override
    public String getMethodName() {
        return "UserPasswordReset";
    }

    @Override
    public String getTag() {
        return "Forget Password Activity";
    }
}

例如，只需执行以下操作：

SoapURL example = new LoginSoap();
String a = example.getTag();

---

a

应等于

“登录活动”

您的实现看起来是正确的。要使用它，您可以在main中执行以下操作：

SoapURL reset = new ResetPasswordSoap();
System.out.println(reset.getUrl());

这是一种在大型系统中最小化耦合的方法。并通过为一起工作的对象组使用公共接口来减少对象之间的依赖性。您可能对面向对象原则还不熟悉，但您已经领先游戏一步了

要将其传递给函数，请执行以下操作：

public JPanel resetPass(SoapURL reset) {
    ...
}

// In main:
JPanel resetPassPanel = resetPass(reset);

接口的主要用途是多态性，或执行相同操作的能力 对多个不同对象的操作， 这正是您在场景中想要的

你的方法非常好，只是需要修改一下

private SoapURL soapURL;
//SoapUrl = LoginSoap (); // This line should be replaced with the Below line
soapURL=new LoginSoap();

String nameSpace = soapURL.getMethodName();
String url = soapURL.getUrl();

由于

LoginSoap

，

SignUpSoap

，

ResetPasswordSoap

类是

SoapURL接口

的实现类，因此SoapURL的引用变量可以存储这些子类中任何一个的对象

soapURL=new LoginSoap();//soapURL.someMethod will call method of LoginSoapClass
soapURL=new SignUpSoap();// will call method of SignUpSoap class
soapURL=new ResetPasswordSoap();

您当前的代码是什么？您的具体问题在哪里？您的接口看起来都是正确的。您是否想编写一段代码来确定应该使用哪种实现？我已经给出了上面的代码，我只是想知道是否可以通过调用接口访问类数据。。比如soupur=LoginSoap（）；大于soapUrl.getUrl（）的值；将更改为LoginSoap ClassYes，有什么问题吗？你能做到，怎么做到？你能给我举个例子或者给我指出任何教程的链接吗
