Problems with adding something to an array

Question

I am trying to find out what I am doing wrong, I think I am way off...I am trying to take two different strings, compare the one to the other and see where the source is equal to the target at any place in the the source. Then I am to add that index to an array list, this is where I am having issues, after the AddArrayList() and putting the index of the match into the array. Please, I have been at this for a while...
this is what eclipse tells me...

Answer 1

the problem i encounter is on if(y==tLength)
    public static ArrayList<Integer> matches(String source, String target) {
        // check preconditions
        assert (source != null) && (source.length() > 0)
             && (target != null) && (target.length() > 0): "matches: violation of precondition";
        ArrayList<Integer> result = new ArrayList<Integer>();
        int sLength=source.length();
        int tLength=target.length();
        int count=0;
        for(int x=0; x<sLength; x++ )
             if ((tLength+x)<(sLength))
                  for (int y=0; y<tLength; y++)
                       if(target.charAt(x+y)==source.charAt(x+y))
                            if(y==tLength)
                                 AddArrayList();
                                 [ArrayList]<int>.add([x]);
                                 count++;
        return result;
    private static void AddArrayList() {
         ArrayList<Integer> result = new ArrayList<Integer>();
         int index = 0;
         result.add(index);
