【Java】java中解析TLV标记字符串

java中解析TLV标记字符串，正在尝试分析TLV字符串：

24 00 35 E1 31 9F 08 02 38 30 9F 37 04 4A 66 6B 69 DF AE 05 01 41 9F 26 08 73 30 35 76 4F 6A 36 4E DF AE 06 0C 33 34 71 76 69 70 6B 4D 53 63 66 55 9F 36 02 00 01 90 00 7B

在本例中，9F08是标记，后跟长度字段和数据。我可以使用当前的输入字符串获取所需的字段，但是可能会出现这样的情况，即标记（“9F08”）也可能位于另一个字段的数据部分。我不知道如何继续进行这项工作
