找不到文件

Question

private void readRandomContacts() throws IOException 
{ 

BufferedReader bufRdr; 
contacts = new ArrayList<Contacts>(); 

File randomContactsFile = new File("C:\randomContacts.csv"); 
try { 
    bufRdr = new BufferedReader(new FileReader(randomContactsFile)); 
    String line = null; 
    String[] a = new String[2]; 

     while ((line = bufRdr.readLine()) != null) 
       { 
        a = line.split(","); 
        Contacts c = new Contacts(a[0], a[1], a[1], a[1], a[2]); 
        contacts.add(c); 
       } 

    } catch (FileNotFoundException e) { 
     Log.d("file not found", "check"); 
     e.printStackTrace(); 
    } 

我似乎無法找到該文件，並且randomContacts.csv確實存在於C目錄中。請幫忙嗎？

Answer 1

嘗試：

File randomContactsFile = new File("C:\\randomContacts.csv"); 
             ^^ these two are important

Answer 2

File randomContactsFile = new File("C:\randomContacts.csv"); 

應該

File randomContactsFile = new File("C:\\randomContacts.csv"); 

你需要逃避\，否則，JAVA會讀\r爲回車。

Answer 3

，你也可以做到這一點（FRONTSLASH）：

new File("C:/randomContacts.csv")
