java - Regex to match "path/*.extension" -

i trying find regular expression match following format:

path/*.file_extension 

for example:

temp/*.jpg usr/*.pdf var/lib/mylib.so tmp/ 

using regex, want store matching parts string array, such as:

string[] tokens; // regex magic here string path = tokens[0]; string filename = tokens[1]; string extension = tokens[2]; 

in case of last case tmp/, contains no filename , extension, token[1] , token[2] null. in case of the: usr/*.pdf token[1] contain string "*".

thank help.

if can use java7 can use named groups this

string data = "temp/*.jpg, usr/*.pdf, var/lib/*.so, tmp/*, usr/*, usr/*.*";  pattern p = pattern         .compile("(?<path>(\\w+/)+)((?<name>\\w+|[*]))?([.](?<extension>\\w+|[*]))?");  matcher m = p.matcher(data); while (m.find()) {     system.out.println("data=" + m.group());     system.out.println("path=" + m.group("path"));     system.out.println("name=" + m.group("name"));     system.out.println("extension=" + m.group("extension"));     system.out.println("------------"); }
