Count the number of pictures

Your Java IDE should have told you, that Region::findAll() returns java.util.Iterator<Match> and not List<Match>.

     if (s.exists(s1.prop("sm37")) != null) {
      System.out.println("Blank");
      }
     else{
         int count = 0;
         while (true) {
             if (s.exists(s1.prop("sm378")) != null) {
                 s.wait(0.5);
                 Iterator<Match> a = s.findAll(s1.prop("sm378"));
                 count = count + fu.getsizeofIterator(a);
                 System.out.println("continue");
             }
             else{
                 count = count + 0;
             }
             if (s.exists(s1.prop("sm379")) != null) {
              System.out.println("Not find");
                 break;
             }
             else {
                 System.out.println("True");
                 s.type(Key.F11,Key.SHIFT);
             }
         }

i need to count the number of pictures ：s1.prop("sm378")

count = count + fu.getsizeofIterator(a); ----- This sentence is not carried out

could you please tell me how to solve this ?

--- fu.getsizeofIterator(a)
it looks like
int getsizeofIterator(Iterator<Match> a) {}
is some method in class/object fu to evaluate and return the count

like this:
public int getsizeofIterator(Iterator<Match> a) {
  int count = 0;
  if (null != a && a.hasNext()) {
    while (a.hasNext()) {
      a.next()
      count++;
    }
  }
  return count;
}

thx for your answer ,

public int getsizeofIterator(Iterator<Match> a) {
  int count = 0;
  if (null != a && a.hasNext()) {
    while (a.hasNext()) {
      a.next()
      count++;
    }
  }
  return count;
}

Pattern st = new Pattern(s1.prop("sm378")).similar((float) 0.99);
     if (s.exists(s1.prop("sm37")) != null) {
      System.out.println("Blank");
      }
     else{
         int count = 0;
         while (true) {
             if (s.exists(st) != null) {
                 s.wait(0.5);
                 Iterator<Match> a = s.findAll(s1.prop("sm378"));
                 count = count + fu.getsizeofIterator(a);

             }
             else{
                 count = count + 0;
             }
             if (s.exists(s1.prop("sm379")) != null) {
                 break;
             }
             else {
                 s.type(Key.F11,Key.SHIFT);
             }
         }

i used this , but result is not ideal . the actual number is 2, but the result of the execution is 10, could you please help to look further ?

It finds more then the 2 you expect, because of standard similarity score of 0.7.

Either use:
s.findAll(new Pattern(s1.prop("sm378")).similar(0.99)) //adjust as needed

or filter the matches in the def:

    while (a.hasNext()) {
      Match match = a.next();
      if (match.getScore() < 0.95) break;
      count++;
    }

thx a lot !!!
