Java Android Studio For循環超出其極限

當我在Android設備上運行下面的代碼時，我得到一個ArrayOutOfBounds異常說y = 6。但是，理論上這是不可能的，因爲for循環的邊界是y < 6.我搜索了可能的解釋，發現沒有。 matrix1Numbers的大小是6乘6，每個維度保持0-5。Java Android Studio For循環超出其極限

for (z = 0; z < 6; ++z) {

       @Override 
       public void beforeTextChanged( CharSequence s, int start, int count, int after) { 

       }

'y'和'z'如何存儲？我的意思是..是靜態還是其他？ – Rothens

@ Rothens，你說得對，我檢查並刪除了我的評論 –

@darkterbears，請告訴我們'Exception'發生在哪裏（在哪一行） –
