正则表达式从链接中提取价值

Question

I have a String like file:///android_asset/GwyXUyisyq . I want to extract the GwyXUyisyq from the rest of the string. The value will change in every instance, but the file:///android_asset/ will always remain fixed. What regex can I use to achieve the same?

Answer 1

You don't need a regex here : Just find the last index of / and replace everything before it :)

    String s = "file:///android_asset/GwyXUyisyq";
    System.out.println(s.replace(s.substring(0,s.lastIndexOf("/")+1), ""));

O/P :GwyXUyisyq
