Java:切片字符串

Question

我的网址总是以数字结尾,例如:

  String url = "localhost:8080/myproject/reader/add/1/";
  String anotherurl = "localhost:8080/myproject/actor/take/154/";

我想提取最后两个斜杠("/")之间的数字.

有谁知道我怎么做到这一点？

你可以拆分字符串:

String[] items = url.split("/");
String number = items[items.length-1]; //last item before the last slash
