Java輸入不匹配從文本文件中讀取

我正在編寫一個程序，它將從充滿學生成績的文本文件中獲取輸入。這些等級取平均值並添加到數組列表中。但是，我無法將文件讀入。我收到輸入不匹配。我已經嘗試將calcAssignmentAverage方法中的循環更改爲小於15（實驗室級別爲15，文本文件中的第二行），但它仍然會導致輸入不匹配。Java輸入不匹配從文本文件中讀取

    final double FINAL_POINTS = 100; 

    //Open input file 
    File myFile = new File("scores.txt");

}

     //read lab average 
     double labAverage = 0; 
     labAverage = calcAssignmentAverage(NUM_OF_LABS, inputFile, LAB_POINTS); 
     currentStudent.setLabAverage(labAverage); 


     //add currentStudent to the list 
     studentList.add(currentStudent);

     Scanner inputFile, double MAX_POINTS) { 

    double sum = 0; 
    double average = 0; 

    for (int i = 0; i < NUM_ASSIGNMENTS; i++) { 
     sum = sum + inputFile.nextDouble(); 
    } 
    average = (sum/MAX_POINTS) * 100; 

    return average; 
}

您的代碼使用不包含的學生類 – aditsu 2013-02-24 20:35:32

對不起，但這是第三次閱讀您的問題，但我不知道究竟需要什麼以及您的錯誤。請指定更多 – Azad 2013-02-24 20:43:59

樣本文件中第二行之後的行號（數字）是什麼？目前你只使用第二行，但如果while循環佔用所有行，則它將無法正常工作，因爲它假設新學生位於第3行。 – Byron 2013-02-24 20:55:28
