当前代码写入Days2.dat

File f1 = new File("Days2.dat");
File f2 = new File("Activities.dat");
f1.delete();
try{
    BufferedWriter writer = new BufferedWriter(new FileWriter(f1, true));
    BufferedReader reader = new BufferedReader(new FileReader(f2));
    while(reader.ready())
    {
        String CDay = reader.readLine();
        String CActivityName = reader.readLine();
        String CSupervisor = reader.readLine();
        String CLocation = reader.readLine();
        String CPaid = reader.readLine();
        String nothing = reader.readLine();
        writer.write("Sunday" + "n");
        if(CDay.equals("Sunday"))
        {
            writer.write(CActivityName + "n");
        }

        writer.write("Monday" + "n");            
        if(CDay.equals("Monday"))
        {
            writer.newLine();
            writer.write(CActivityName + "n");
        }            

        writer.write("Tuesday" + "n");
        if(CDay.equals("Tuesday"))
        {
            writer.newLine();
            writer.write(CActivityName + "n");
        }

        writer.write("Wednesday" + "n");
        if(CDay.equals("Wednesday"))
        {
            writer.newLine();
            writer.write(CActivityName + "n");
        }

        writer.write("Thursday" + "n");
        if(CDay.equals("Thursday"))
        {
            writer.newLine();
            writer.write(CActivityName + "n");
        }
    }
    writer.flush();
    writer.close();
    reader.close();
} 
catch (IOException ex) {
    Logger.getLogger(StartUpFrame.class.getName()).log(Level.SEVERE, null, ex);
}

当前输出是这样的(有点长，抱歉)-错误是明显的:

Answer 1

无论我们实际处理的是哪一天，您目前每次都在写星期几，这是不完全正确的。

由于在您的文件中有多个星期，我将尝试如下操作:

• 为一周中的每一天创建一个List(或其他一些对象)。如果你不想创建这么多对象，地图可能更有用，例如Map<String, List<String>>
• 使用您的CDay变量确定我们正在处理的是一周中的哪一天(就像您目前正在做的那样)。
• 如果匹配，则将活动添加到列表中。
• 一旦文件被读取，将列表的内容写入每周每天的新文件中。
