}大家好，以上是程式碼。程式是一個百萬大富翁的遊戲。需要從另一個Questions.txt檔中讀入題目並顯示。
但是題目中有中文有英文，如果遇到中文就顯示不出來，請問是程式碼哪邊有問題嗎?
...<div class='locked'><em>瀏覽完整內容，請先 <a href='member.php?mod=register'>註冊</a> 或 <a href='javascript:;' onclick="lsSubmit()">登入會員</a></em></div><div></div> Questions.txt檔案設為utf8編碼試看看
記事本存檔時選utf8或用notepad++ 本帖最後由 adarkair 於 2016-1-17 05:09 PM 編輯
從reference看到:
FileReader的註解有提到這段
The constructors of this class assume that the default character encoding and the default byte-buffer size are appropriate. To specify these values yourself, construct an InputStreamReader on a FileInputStream.
大致上是說此類別是用預設的文字編碼來解讀這個檔案，所以有可能造成中文字解不出來，
它也提到要設定文字編碼可以使用InputStreamReader配合FileInputStream來讀取
可以嘗試使用下面這段取代你原先宣告reader那段，並且把檔案存成utf-8編碼
BufferedReader reader = new BufferedReader(InputStreamReader(new FileInputStream("檔案位置"), "UTF-8"));
...<div class='locked'><em>瀏覽完整內容，請先 <a href='member.php?mod=register'>註冊</a> 或 <a href='javascript:;' onclick="lsSubmit()">登入會員</a></em></div> 檔案有檔案encoding, java也有default encoding
讀檔時要確認檔案的編碼 這樣才不會亂掉 檔案encoding utf8編碼試看看<br><br><br><br><br><div></div> 檔案弄成utf8試看看..... 應該是文字檔案編碼，與你讀取時的編碼設定不同，
才會有這種狀況。 檔案的 Encoding 設定為 UTF-8 的編碼，試試看
