如何在一个类的另一个类中使用操作侦听器中的目录路径变量？

private String directoryPath;

public void setDirectoryPath(String path) {
    this.directoryPath = path;
}

public class AnotherClass {
    private OperationListener operationListener;

    public void setOperationListener(OperationListener listener) {
        this.operationListener = listener;
    }

    public void someMethod() {
        String directoryPath = "/path/to/directory";
        operationListener.setDirectoryPath(directoryPath);
    }
}

public void performOperation() {
    // 使用目录路径变量进行相关操作
    File directory = new File(directoryPath);
    // ...
}
