錯誤：線程「main」中的異常java.lang.ArrayIndexOutOfBoundsException：-1

-1

我在Java中使用這些代碼來對PRINCE進行加密和解密。這些是Sbox和Sbox Inverse的代碼。每當我運行該程序，我得到和錯誤消息：錯誤：線程「main」中的異常java.lang.ArrayIndexOutOfBoundsException：-1

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: -1 
    at prince.SInv(prince.java:146) 
    at prince.Encrypt(prince.java:485) 
    at prince_analysis_main.main(prince_analysis_main.java:21)

我已經實現try和catch方法參照http://mcnewton.org/blog/tag/exception-in-thread-main-java-lang-arrayindexoutofboundsexception-5/但它並沒有解決問題。我可以知道，如果這個錯誤信息是由有限的內存分配引起的還是執行錯誤？

這不是完整的代碼。你的主要方法在哪裏？在哪一行是拋出的異常。請學習基本的調試。你的[其他問題]（http://stackoverflow.com/questions/27126145/java-formula-parsing-error）也沒有做得太好。順便說一句，你爲什麼創建一個新的帳戶？ – 2014-12-02 09:48:49

數組索引越界異常意味着你試圖訪問不存在數組的索引。

示例如果您的數組中有5個元素表示要求第6個元素。

我會看看你的SInv函數爲你的數組索引計算。
