calling a public method of the same class twice in another public method

Question

i have two methods in same class method1() and method2(). method 1() is to read a 'String' and extract integers from that string and method2 () is to perform a click operation. This click operation changes the 'string' which is the input of method1 () . Evreythign is working fine but my problem is Case 1 When i am calling these two methods from another class in following way -

method1();-------- 1
method2();-------- 2
method1();---------3

i get a clear result which shows the result of line 1 is different from line 3 becuase the string was changed by line 2 BUT

Case 2 when i am calling method1() inside method2 () in the same class in the following way -

method2();{
method1();---------1
click statement of method2;
method1();---------2
}

and calling this method2(); from another class it doesnt work line 1 and line 2 gives same result.

where i am wrong in case 2 or its not possible to call a public method of the same class twice in another public method ?? please guide.

if you need code details here it is :-

 public void clickOnFaces(int n) {
       ArrayList<Integer> ratingLikes = ratingLikes(n);
        int likes = ratingLikes.get(0);
        int total = ratingLikes.get(1); 

        seleniumclient.elements(Mappings.face).get(n).click();

       ArrayList<Integer> updatedRatingLikes = ratingLikes(n);

            int c = updatedRatingLikes.get(0);
        int d = updatedRatingLikes.get(1);
    }





    public ArrayList ratingLikes(int n) {
        seleniumactions.waitForElement(Mappings.ratingLikes);
        ArrayList<Integer> likes = new ArrayList<>();
        Pattern p = Pattern.compile("\\d+");
        Matcher m = p.matcher(seleniumclient.elements(Mappings.ratingLikes).get(n).getText());
            while (m.find()) {
                likes.add(Integer.parseInt(m.group()));
                 }
            return likes;

Issue is the value of 'c' and 'd' is same as 'likes' and 'total'. how ever they change when i keep only the click statement in clickonfaces() and call these mthods from different class example :

object.ratingLikes(int 0);
object.clickOnFaces(int 0);
object.ratingLikes(int 0);
