Java类中的相对路径不同/在执行过程中发生更改

问题：两个类试图使用同一段代码访问两个不同的（相对）路径

步骤：

我运行

Client.java

客户端打印C:\Users\user\git\x\y作为相对路径（正确路径）

程序从

SQLiteDB.java

SQLiteDB现在打印

C:/WINDOWS/System32

，同时在客户端中设置为

C:\Users\\git\x\y

Class

client.java

：

public class Client {

@SuppressWarnings("unused")
private static TUI tui;
public static final String RELATIVE_PATH = Paths.get("").toAbsolutePath().toString();

public static void main(String[] args) {
    System.out.println(RELATIVE_PATH); 
    // Prints C:\Users\user\git\x\y
    // The above path is the correct path

    tui = new TUI();        
}

类

SQLiteDB.java

public class SQLiteDB {
public static final String RELATIVE_PATH = Paths.get("").toAbsolutePath().toString();

public static void initializeDB() {
    //<snip>
}

private static String getSchemaStatements() {
    List<String> lines = null;
    try {
        System.out.println(RELATIVE_PATH); // Prints C:/WINDOWS/System32
        System.out.println(Client.RELATIVE_PATH); // Now suddenly also prints C:/WINDOWS/System32 while it was set as C:\Users\user\git\x\y
        lines = Files.readAllLines(schema);
    } catch (IOException e) {
        e.printStackTrace();
    }
    //<snip>
}

客户机在哪里定义？您有一个类
Client
，注意区分大小写在Java中是一个重要的东西@JorgeCampos Oops，这应该是客户端（复制错误）好的，那么，您如何/在哪里调用SQLiteDB类？可能是重复的您没有回答我的问题，“您如何/在哪里调用SQLiteDB类？”了解您的项目设置、类的连接方式以及您的呼叫方式，肯定会帮助我们帮助您。通过stacktrace，我看到您在一个容器（tomcat）中运行，而您没有提到这个容器，并且您的客户机类有一个main方法，所以请解释一下您的项目是如何设置的
