Question

我试图写入文件Days2.dat在这样的特定格式：

Sunday 
Advanced Open Water Dive Certificate 
Sailing 
Generation Next 

Monday 
Helping Hands 
Beach Touch Rugby 
Running Club 
Yoga Club 
Tennis Lessons 

Tuesday 
Recycling Club 
Best Buddies 
Crochet Club 
Movie Club 
Shooting Club 

Wednesday 
Table Tennis 
Modern Dance 
Contemporary Dance 
Gavel Club 

Thursday

Gym Training 

当点击一个按钮，的actionPerformed应该：

• 从文件中读取Activities.dat并确定活动的日期和名字

• 写入格式如上Activities.dat格式文件Days2.dat是这样的：

日

ActivityName

主管姓名

位置

付费？

例如

Sunday 
Advanced Open Water Dive Certificate 
Mr.Jones 
N/A 
Yes 

Sunday 
Sailing 
Mr. Jackson 
N/A 
Yes 

Sunday 
Generation Next 
Ms.Steele 
N/A 
Yes 

Monday 
Helping Hands 
Ms.Wafa 
ANX0 
No 

Monday 
Beach Touch Rugby 
Mr.Jones 
N/A 
No 

当前代码写入到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); 
} 

的电流输出，但是是这样的（有点长，遗憾） - 错误是显而易见的：

Answer 1

您目前正在写每周的星期几ime不管我们实际处理哪一天，这是不正确的。

由于有一周多天在你的文件我想尝试的东西如下：

• 创建List（或其他对象）一周的每一天。如果您不想创建如此多的对象，则地图可能更有用。 Map<String, List<String>>
• 确定我们正在使用您的CDay变量处理的星期几（正如您当前所做的那样）。
• 如果是匹配，则将该活动添加到列表中。
• 一旦文件被读取，将列表的内容写入一周中每一天下的新文件。
