hi LULU
i think this exercise is from the String lesson
the String class has lot of efficient methods in the java language, what u need here is to extract a substring from the the input string
the substring has 2 arguments: one for the begining and one for the end; u know that the begining starts on the 5th caracter of the string (in ur example the URL), and ends with the 5th caracter to the right
so u have to use ur substring like this:
...
URL.substring(4, (URL.length-4))
...
