我遇到了 indexoutofboundsexception，我搜索了互联网并查看了几种不同的解决方案，但这段代码没有运气。
这是我的错误信息：
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);
一些帮助将不胜感激。谢谢你！
