如何通过Java使用2类中1类的方法变量？

Question

public static class One {

    @Override
    public String interact(String... values) {
        String actualTextOne = "test";
        return actualTextOne;
    }
}

public static class Two {

    @Override
    public String interact(String... values) {
        String actualTextTwo = "test";

        /*    Here I need to compare actualTextOne and actualTextTwo, but the problem is that I can't find solluction how to use actualTextOne in Two class*/

        return actualTextTwo;
    }
}

Answer 1

你不能这样做。
请检查java中的变量范围。

这里一个可能的解决方案是从类One调用方法interact 。 像这样的东西

public static class Two {

    @Override
    public String interact(String... values) {
        String actualTextTwo = "test";

        One one = new One();
        String actualTextOne = one.interact(values);
        
        // compare values here

        return actualTextTwo;
    }
}

Answer 2

1. 如果您不使用它，为什么在您的类中函数有参数？

2. 只有在嵌套时，您才能使用静态标记您的类，否则您需要这样做：

    class Two { static public String interact(String... values) { String actualTextTwo = "test"; return actualTextTwo; }

   }

3. String textOne = One.interact(""); String textTwo = Two.interact(""); System.out.println(textOne==textTwo);
