jexcel API中的IndexOutOfBoundsException

Question

我有一個indexoutofboundsexception，我瀏覽了互聯網並查看了幾種不同的解決方案，但沒有使用此代碼。

這裏是我的錯誤信息：

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) 

線81：

WritableSheet sheet = copy.getSheet(0); 

有些幫助將是非常非常感謝。謝謝！

嘗試使用，而不是getSheet
