java /bufferedwriter / newLine

Question

mam taka fukcnje :

            public static String showClassError() throws IOException {

                Iterator<String> iterator = errorCount.keySet().iterator();
                String response = "";
                while(iterator.hasNext()) {
                    String key = iterator.next().toString();
                    Integer value = errorCount.get(key);
                    System.out.println(key + " : " + value);
                    System.getProperty("line.separator");
                    response+=key + " : " + value + "\n";
                    System.lineSeparator();
                }    
                return response;
            }

ona przechodzi po mapie i daje mi zliczone logi , wynik :

[com.sbbetting.applications.betting.api.text.Texts : 1346
[com.sbbetting.odds.common.transactions.TransactionsController : 1

        bw.write(showClassError());
        bw.newLine();
