Java方法在運行後不打印任何東西

Question

我正在用java製作一個小型紙牌遊戲。現在，我正在進行手頭分類。但是，當我運行方法'handclassifier'時，我什麼也沒得到。以下是對Eclispe的輸出到控制檯的例子：

標準輸出

Your hand: 6 of Spades, Queen of Spades 
Creek: 10 of Spades, 9 of Spades, Queen of Clubs 
Current value: 

正如你所看到的，handclassifier方法完全不返回任何東西，甚至當一對的要求得到滿足。我已經在前兩種方法之後運行，以便卡片可以加載並通過該方法進行分類。比較代碼中有錯嗎？

Answer 1

while(stop = false) { 

應該

while(!stop) { 

或

while(stop == false) { 

您比較它的分配false到stop變量，而不是目前的價值爲false。
