    In your example, the count variable is responsible for the number of lines, but as you can see, at the end of the program this variable is equal to the total number of lines in all files.

    In order to calculate separately for each file, you need

     int count = 0;

    replaced by

     Map<File,Integer> fileMap = new HashMap<>();

    And rewrite the cycle a bit

     for (File fill: FilesFind) { BufferedReader reader = new BufferedReader(new FileReader(fill)); int count = 0; while ((search = reader.readLine()) != null) { if (search.contains(mask) && !search.isEmpty()) { count++; System.out.println("Name files : " + fill.getName() + " --- > " + " String : " + count); } } fileMap.put(fill, count); reader.close(); }

    PS If you don’t need to use the number of lines for each file anywhere else, you can delete the map and simply create the count variable in the for loop
