使用java 实现递增截取目录，目录路径为：/nas/ytdata/TM03/rawLog/2023/04/02/

以下是Java代码实现：

String path = "/nas/ytdata/TM03/rawLog/2023/04/02/";
String[] dirs = path.split("/");

for(int i=0; i<dirs.length; i++){
    String subPath = "";
    for(int j=0; j<=i; j++){
        subPath += dirs[j] + "/";
    }
    System.out.println(subPath);
}

输出结果：

/
/nas/
/nas/ytdata/
/nas/ytdata/TM03/
/nas/ytdata/TM03/rawLog/
/nas/ytdata/TM03/rawLog/2023/
/nas/ytdata/TM03/rawLog/2023/04/
/nas/ytdata/TM03/rawLog/2023/04/02/
