Answer 1

Hey the problem is in this method

public void returnFiles(){
        for(int i = 0; files.size() <= i; i++){
            System.out.println( i + ". Ist: " + files[i]);
        }

 }

Precisely, on the

files[i]

You are trying to access your ArrayList instance variable as if it were a an Array. Just change that for

files.get(i)

You have to use the method get(int index) from the ArrayList<> class.
