这是我的代码，我以为我输入的所有内容都是正确的：

但是当我尝试编译并运行它时，它给了我这些错误：
Exception in thread "main" java.lang.NumberFormatException: For input string: "112211324135412"
at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)
at java.lang.Integer.parseInt(Integer.java:495)
at java.lang.Integer.parseInt(Integer.java:527)
at Proj5.gradeSingleQuiz(Proj5.java:52)
at Proj5.main(Proj5.java:27)
我在想也许我没有将该数字的字符串转换为 int 正确但回头看我想我做了，我真的只是不知道这些错误是什么。根据eclipse，在编译之前代码没有任何问题。
我从中提取的文字是这个。
4563123,112211324135412
2312311,222121324135211
2312345,112211324135421
5527687,212111313124412
7867567,111111111111111
第一个数字是学生证，第二个数字是基于数字的答案；T=1 F=2 A=1 B=2 等等。
提前致谢。
编辑：
将我上面的代码更改为 Long 并修复了这些错误，但现在它给了我一个超出范围的异常 5abc [p] = ara[j]%10;我知道这不是我的原始问题，但如果有人能告诉我为什么会这样，我会非常感激，我是不是觉得 5 没有出界？
再次感谢
