Find the index of the first space character?

Question

I've written functional code that will read and write data values to an arraylist. Though it returns everything, if a value has multiple words how can I exclude the first one?

  // 3 points
static ArrayList<String> Q2(String filename) {

    // You are given a file (filename) containing a different random phrase on each line. Return an
    // ArrayList containing each phrase, but without the first word of each phrase.
    //
    // Example: If the files contains the 2 phrases "roofed crossover" and "beneficiary charles frederick worth" the
    // ArrayList should contain "crossover" and "charles frederick worth"
    ArrayList<String> al = new ArrayList<String>();

    try {
        for(String s : Files.readAllLines(Paths.get(filename))){


            al.add(s.substring(9));
        }
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    return al;
}

Heres what the grader says:

Incorrect on input: data/phrases0.txt
Expected output : [algae, blood platelet, charles frederick worth, convert, crossover, eye movement, ferocity, itch, lake albert, loewi, mountainside, peach, sontag, specialty, supposition, surprised endometriosis, testimonial, trial golden fleece, waterproofing, wrongdoer]
Your output     : [ferocity, peach, ed algae, wi, ossover, ry charles frederick worth, ised endometriosis, wrongdoer,  lake albert, ng waterproofing, d eye movement, mountainside, g testimonial, c itch, tal sontag, ive blood platelet, golden fleece, ic specialty, convert, s supposition]

I've gotten it to return some values back without the first string however some words are larger than the sub string can reach.

All you need is remove the first word stand before the space, then just use this code: get sub string of input string from position of the space char.

for(String s : Files.readAllLines(Paths.get(filename))){
    al.add(s.substring(s.indexOf(" ")+1)));
}
