這段代碼應該會在每次死亡時產生新的敵人。這包括敵人隨機生成一點健康，但我的程序只是使用與前一個敵人相同的健康狀態，因此不斷循環到「敵人已被擊敗」，我試圖讓敵人健康並生成特定的敵人Enemy.java，但我很努力地掌握正確的OOP，即使我已經使用了一些教程。Java如何在每次while循環開始時獲得一個隨機數？

這是很多代碼。如果您希望我們花時間試着瀏覽它，則需要花時間格式化。你可能想讀這個：如何創建[mcve]。 –
歡迎來到Stack Overflow！看起來你正在尋求作業幫助。雖然我們本身沒有任何問題，但請觀察這些[應做和不應該]（http://meta.stackoverflow.com/questions/334822/how-do-i-ask-and-answer-homework-questions/338845＃338845），並相應地編輯您的問題。 –
那麼如果你想例如'enemyHealth'有一個隨機數，你必須給它分配一個：'enemyHealth = rand.nextInt（）;'或者任何你正在尋找的取值範圍。 – markspace
