**a.txt :**

```
1,2,3
1,2,6
2,4,5

```

**Reading and splitting**

```
String wynik = readFileAsString("a.txt");
String[] wyniki = wynik.split("");

```

I can't seem to find a way to split String out after newLines that are in file, and not specified like this (this is what I found on all other examples on stackoverflow):

```
1,2,3\n1,2,6\n2,4,5\n

```

My readFileAsString works correctly, and it actually reads it that way (without splitting):

```
1,2,31,2,62,4,5

```

I know I could add something to my file, to make it split by it, eg

```
1,2,3t
...

```

But I also need that file to be clear and without any unnecessary symbols.

Entire thing looks like this:

```
public static String readFileAsString(String file) {
    String line, results = "";
    try {
        BufferedReader reader = new BufferedReader(new FileReader(file));
        // readLine() zwraca nulla na koncu pliku, stad zabezpieczenie
        while ((line = reader.readLine()) != null) {
            results += line;
        }
        reader.close();
        // return results;
    } catch (IOException e) {
        System.err.println("Error");
    }
    return results;
}

    public static void main(String args[]) {

        String wynik = readFileAsString("a.txt");
        System.out.println(wynik);
        String[] wyniki = wynik.split("[\\r\\n]+");

        ArrayList<Trojka> wynikArrList = new ArrayList<Trojka>();

        for (int i = 0; i < wyniki.length; i++) {
            String[] temp1 = wyniki[i].split(",");
            int m = 0;
            int n = 0;
            int t = 0;
            try {
                m = Integer.parseInt(temp1[0]);
            } catch (Exception e) {
            }
            try {
                n = Integer.parseInt(temp1[1]);
            } catch (Exception e) {
            }
            try {
                t = Integer.parseInt(temp1[2]);
            } catch (Exception e) {
            }

            Trojka temp = new Trojka(m, n, t);

            boolean newRecord = true;
            for (Trojka a : wynikArrList) {
                if (a.getM() == temp.getM() && a.getN() == temp.getN()) {
                    a.addT((int) temp.getT());
                    newRecord = false;
                    break;
                }
            }
            if (newRecord) {
                wynikArrList.add(temp);
            }
        }

        wynik = "";

        for (Trojka a : wynikArrList) {
            wynik += a.getM() + "," + a.getN() + "," + a.getT() + "\n";
        }

        System.out.println(wynik);  

    }
}
