插入太多数据时，请获取ArrayIndexOutBound异常

Question

当我放置较少的数据时，运行良好，但是当数据更大时，我没有设置数组尺寸限制，我错了？

   public static void readQuestions(InputStream inputStream, Context context) {
    BufferedReader reader = null;
    try {
        reader = new BufferedReader(new InputStreamReader(inputStream));
        String line;
        while ((line = reader.readLine()) != null) {
            String[] contents = line.split("-");
            String marksId = contents[0];
            String quesId = contents[1];
            String subject  = contents[2];
            String question = contents[3];
            CDataSource cDataSource=CDataSource.getInstance(context);
            cDataSource.addMidSemQuestions(new MidSemQuestions(marksId, quesId, subject, question));
        }
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

为什么它仅在第一次出现错误？？

String[] contents = line.split("-");
String marksId = contents[0];
String quesId = contents[1];
String subject  = contents[2];
String question = contents[3];

检查此代码，如果 cottents 大小在您的情况下不是4号，则将抛出arrayindexoutofBoundSexception。

。

也是logcat

Caused by: java.lang.ArrayIndexOutOfBoundsException: length=1; index=1

清楚地说，内容的大小为1，您正在尝试在位置2，即内容[1]。

。

如果有帮助，请将其放在尝试中。
