Java，比較兩個字符串數組的值

Question

我想完成學校的任務，並且遇到問題，看看兩個字符串數組中的每個元素是否相等。我看到無處不在，似乎我已經在正確地做，但事實並非如此。

真的很快，作業是用戶輸入測驗編號和T/F測驗（2 TTTF F ...）的解決方案，然後輸入信息給學生，第一個姓，學生ID以及他們對這個測驗的回答。

如果我在回答鍵中輸入了T T T F F T T和學生答案中的T T T F F F F，那麼它們就會被視爲相等，我無法弄清楚原因。我會發布我所有的代碼，但在適當的循環周圍添加星星，我認爲問題是...謝謝你的任何幫助，這讓我瘋狂！

Answer 1

if((studentArr[i + 2]).equalsIgnoreCase(answerKey[i])); 

不應該，如果with語句結束時的條件;
