Question

我有一个indexoutofboundsexception，我已经浏览了互联网，并查看了几个不同的解决方案，但没有运气这个代码。

这是我的错误消息：

Exception in thread "main" java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
at java.util.ArrayList.RangeCheck(ArrayList.java:547)
at java.util.ArrayList.get(ArrayList.java:322)
at jxl.write.biff.WritableWorkbookImpl.getSheet(WritableWorkbookImpl.java:408)
at Segmentation.main(Segmentation.java:81)

第81行：

WritableSheet sheet = copy.getSheet(0);

非常感谢一些帮助。谢谢！

尝试使用createSheet而不是getSheet

jexcel API中的IndexOutOfBoundsException
