所以我用过DataInputStream、FileInputStream、BufferInputStream、FileReader、BufferedReader、Scanner，随便你说。它们都抛出 FileNOtFoundException 或 CorruptedStreamException。
异常 java.io.FileNotFoundException: java.io.FileReader@253498.data (The system cannot find the file specified) 被抛出在 FileReader 使用文件名“Accounts.txt”初始化的行，这是一个文件我已经在 bin 中使用所需的文本进行了初始化。
