如何设置 setter 和 getter 以通过测试用例。凯撒密码类型问题

Question

我需要帮助从提供的主要方法中清除一些测试用例。我必须设置具有设置器和 getters 以及翻译的 class，但我被卡住了。

这是带有测试用例的class。

                // This is just here to see if the if statement failed
            }
        }
        return english;
    }


}

我试图通过更改

在 getter 方法中存储一个值

 public void translateSaurToEng(String saurianToEnglish)

和

 public void translateEngToSaur(String englishToSaurian)

进入

 public String translateSaurToEng(String saurianToEnglish)

 public String translateEngToSaur(String englishToSaurian)

这样我就可以 return 一个值并存储它以备后用。

然后我做了这个

public String getSaurian()
{
    //Just seeing what the output is
    this.saurian = translateEngToSaur(english);

    return this.saurian;
}

public String getEnglish()
{
    this.english = translateSaurToEng(saurian);

    //Just seeing what the output is for english
    System.out.println("This is getEnglish   "+ english);

    return this.english;
}

但该方法不兼容，因为

 translateSaurToEng(saurian)

无效，这就是为什么我将其更改为

public String translateSaurToEng(String saurianToEnglish)

然后尝试这样做，但由于错误而不允许我这样做。

感谢您提供的任何帮助。

Answer 1

你很接近！问题实际上出在您的 setter 方法中。除了将传递的字符串设置为一个字段外，您还应该翻译传递的字符串并将该翻译设置为另一个字段。

即

public void setSaurian(String newSaurian)
{
     //this is what you have now:
    saurian = newSaurian;

     //this is what you need to add:
    english = translateSaurToEnglish();
}

如果你在两个 setter 方法中都这样做，那么你 getter 方法应该能够 return 它们的相应成员而无需任何其他代码。

public String getEnglish()
{
    //this is no longer necessary:
         //this.english = translateSaurToEng(saurian);

    //Just seeing what the output is for english
    System.out.println("This is getEnglish   "+ english);

    return this.english;
   }
