(Java) Error while continuing to traverse TXT lines

Question

good night!

I need that even if it reaches the condition total_min < 720 He keeps going through the lines. The 720 are the total minutes before lunch, when reached should separates the activities to be performed after lunch.

• I need to make a system that reads a TXT(intput.txt file).
• This file has several lines.
• Each line an activity with run time (30min, 45min, 60min)
• Activities should start at 9 am.
• Half day (12:00) lunch break
• Generate a TXT with organized activities (output.txt)

intput.txt

Correr 60min
Estudar 30min
Ler 45min
Escrever 60min
Caminhar 45min
Jogar 30min

Example as it should be the output.txt file

09:00 Correr 60min
10:00 Estudar 30min
10:30 Ler 45min
11:15 Caminhar 45min
12:00 Almoço 60min
13:00 Jogar
(...)

My code:

  static int i = 0;

public static void main(String[] args) throws IOException {
    // TODO code application logic here

    ArrayList<String> antes_almoco = new ArrayList<String>();
    ArrayList<String> depois_almoco = new ArrayList<String>();


    int total_min = 540;
    int horas = total_min / 60;
    int minutos = total_min % 60;


    String trinta = "30min";
    String quarentaCinco = "45min";
    String sessenta = "60min";
    boolean trinta_min = false;
    boolean quarentaCinco_min = false;
    boolean sessenta_min = false;

    String nomePc = System.getProperty("user.name");
    String path = "\\input.txt";
    String outputDir = "\\output.txt";

    FileReader arq = new FileReader(path);
    BufferedReader lerArq = new BufferedReader(arq);
    String linha;

    //Output   
    File file2 = new File(outputDir);
    FileWriter arq_output = new FileWriter(file2, true);
    PrintWriter gravarArq = new PrintWriter(arq_output);

    if (!file2.exists()) {
        file2.createNewFile();
    }

    while ((linha = lerArq.readLine()) != null) {



            trinta_min = linha.toLowerCase().contains(trinta.toLowerCase());
            quarentaCinco_min = linha.toLowerCase().contains(quarentaCinco.toLowerCase());
            sessenta_min = linha.toLowerCase().contains(sessenta.toLowerCase());

            if (sessenta_min == true && total_min < 720) {
                total_min += 60;
                antes_almoco.add(linha);
            }

            if (trinta_min == true && total_min < 720) {
                total_min += 30;
                antes_almoco.add(linha);
            }

            if (quarentaCinco_min == true && total_min < 720) {
                total_min += 45;
                antes_almoco.add(linha);
            }

            if (total_min == 720) {
                total_min += 60;
                antes_almoco.add("12:00 Almoço");
            }


    }



    for (String cont : antes_almoco) {
        System.out.println(cont);
        gravarArq.printf("%d:%02d %s \n", horas, minutos, cont);
    }

    for (String cont : depois_almoco) {
        System.out.println(cont);
        gravarArq.printf("%d:%02d %s \n", horas, minutos, cont);
    }

    lerArq.close();
    gravarArq.close();
    arq.close();
}

Answer 1

See if it makes sense to you.

Remove the condition total_min < 720 if and in place of antes_almoco.add(linha) place:

if (total_min < 720) {
    antes_almoco.add(linha);
} else if (total_min > 720) {
    depois_almoco.add(linha);
}

I suggest encapsulating this section in a function to reuse the code.
