Netbeans FileReader FileNotFound文件在文件夹中的异常？ [英] Netbeans FileReader FileNotFound Exception when the file is in folder?

问题描述

所以问题是我每次尝试在NetBeans或Eclips上加载代码时都会发生异常，但是当我尝试通过TextMate运行代码时，一切正常！

我试图把绝对地址，改变文本文件等..没有帮助！有人可以帮我或告诉为什么不能用IDE运行？

谢谢

  void loadFile（）{
 try {
 list = new LinkedList< Patient>（）; 
 
 FileReader read = new FileReader（a.txt）; 
扫描仪扫描=新扫描仪（读）; 
 
 while（scan.hasNextLine（））{
 String Line = scan.nextLine（）; 
 String [] subArray = new String [5]; 
 subArray = Line.split（，）; 
 int a = Integer.parseInt（subArray [4]）; 
 
 list.add（new Patient（Integer.parseInt（subArray [0]）），subArray [1]，subArray [2]，subArray [3]，a））; 
} 
} catch（FileNotFoundException e）{
 JOptionPane.showMessageDialog（null，该文件不存在！+\\\
Program正在终止，找不到文件 JOptionPane.INFORMATION_MESSAGE）; 
 System.exit（0）; 
} 
 cap = list.size（）; 
 search_names = new int [cap]; （int i = 0; i< list.size（）; i ++）{
 search_names [i] = i; 
} 
 setNames（search_names）; 
} // end loadFile 
  

调试日志：

解决方案

在netbeans中，默认工作目录始终是根文件夹，我的意思是包含名称为src，build等的文件夹的文件夹。将文件与这些文件夹一起放置，它将做的诀窍。

so the problem is that I am having exception thrown each time I try to load the code below on NetBeans or Eclips, but when I try to run it thru TextMate everything works fine!

I tried to put the absolute address, changed the text file etc.. didn't help!

Can someone help me or tell why it won't run with IDE?

Thanks

void loadFile() {
    try {
        list = new LinkedList<Patient>();

        FileReader read = new FileReader("a.txt");
        Scanner scan = new Scanner(read);

        while (scan.hasNextLine()) {
            String Line = scan.nextLine();
            String[] subArray = new String[5];
            subArray = Line.split(",");
            int a = Integer.parseInt(subArray[4]);

            list.add(new Patient(Integer.parseInt(subArray[0]), subArray[1], subArray[2], subArray[3], a));
        }
    } catch (FileNotFoundException e) {
        JOptionPane.showMessageDialog(null, "The file does not exist!" + "\nProgram is terminating.", "File Not Found", JOptionPane.INFORMATION_MESSAGE);
        System.exit(0);
    }
    cap = list.size();
    search_names = new int[cap];
    for (int i = 0; i < list.size(); i++) {
        search_names[i] = i;
    }
    setNames(search_names);
}//end loadFile

解决方案

In netbeans the default working directory is always the root folder, i mean the folder which contains the folders which name "src", "build" etc. Place the file along with these folders and it will do the trick.
