存储此数据的可能方法有哪些？

Question

好吧，我需要将这些数据用于至少两个类：

   String navHome = "home";
    String navAbout = "about";
    String navUpload = "upload";
    String navUploadProc = "uploadProc";
    String navStartUpload = "startUpload";
    String navContact = "contact";
    String navSearch = "search";
    String navManual = "manual";
    String navBackToGmis = "backToGmis";

我想把它粘贴到其他类中，但它违反了编程原则，因为它重复了同样的事情。文本和XML文件不适合存储数据，继承不是一种选择，因为Java不支持多重继承...任何想法？

是的，我知道你们大多数人都会觉得迟钝，但我需要知道这些。

如果这些是常量，那么你可以在一个类（或接口）中声明它们并在另一个类中使用它们：

<强> A.java ：

public class A {
    public static final String navHome = "home";
    public static final String navAbout = "about";
    public static final String navUpload = "upload";
    public static final String navUploadProc = "uploadProc";
    public static final String navStartUpload = "startUpload";
    public static final String navContact = "contact";
    public static final String navSearch = "search";
    public static final String navManual = "manual";
    public static final String navBackToGmis = "backToGmis";

    . . .
}

<强> B.java ：

import static A.*; // or list each String in a separate import

public class B {
    . . . // code can use nav* as if they were declared in class B
}
