Java scanner file 报错的问题 ?报错

在mian 方法里面

Scanner keyboard = new Scanner(System.in);

System.out.print("Enter the filename to read from: ");

String filename = keyboard.nextLine();
System.out.print(filename);

      File file = new File(filename);   

Scanner inputFile = new Scanner(file); //这一句系统报错

      StringTokenizer token;      
      while (inputFile.hasNext()){          
      String line = inputFile.nextLine();      
      token = new StringTokenizer(line, "");   
      String firstName = token.nextToken();       
      String lastName = token.nextToken();      
      String IDString = token.nextToken();  

        系统报错为：
            Enter the filename to read from: C:\Users\15220\OneDrive\student_record.txt

C:\Users\15220\OneDrive\student_record.txtException in thread "main" java.io.FileNotFoundException: C:\Users\15220\OneDrive\student_record.txt (???????????)
