Java：如何解析字符串？

Question

How to get last path path_X ?

/some/random/path_1/
/some/random/path_2

Thus, it is necessary to use 3rd party libraries like Guava or Apache Commons .

Answer 1

尝试这个：

final String last = Paths.get("/some/random/path_1/").getFileName().toString();

Answer 2

我相信这也可以，是吗？

String fileName = new File(path).getName();

Answer 3

Another approach would be

String s = "/some/random/path_1/";
String[] sa = s.split("/");

String last = sa[sa.length-1]);
