在此代碼後，「設置」的價值觀，我設置對象的值，然後把它們放到叫做的Java如何恢復被改變

敵人的數組。之後，我使用敵人陣列更改對象元素的值。使用敵人數組。在元素陣列的「HP」值達到零之後，它將

轉移到下一個元素上。我把它使用戶可以返回到前一個元素

，並重新做，但該元素仍然有當用戶第一次

改變他們爲相同的值。我把所有最初定義

值到一個方法，並試圖調用它，所以它可以重置「設置」和敵人數組，但我不是

運氣。有什麼辦法可以正確地做到這一點？

您需要不可變的數據結構，以便您可以快照您的狀態！ – Sikorski

陣列也沒有任何收藏有UNDO方法，你需要設計你自己的，你保持最後的狀態的數據容器，並在需要時按需恢復它

我該如何製作這個容器？ –

紀念圖案！ –

@RaminAmiri您需要兩個集合，一個「當前」和一個「舊」。當有人對當前進行更改時，首先更新舊收藏。 –

這裏有很多東西沒有意義：

在復位功能：

// This stats[] array is local, it won't effect the one out side of the function... 
stats[] enemies = new stats[3]; // Why size 3 if only use 2? first index is 0. 
enemies[1] = new stats(); // This new stats instance will be override next line, so it have no effect. 
enemies[1] = gob; // here you share reference to the gob instance, not copying it. so any change on 'enemies[1]' will in fact be apply on gob. 
enemies[1].getName(); // Do nothing... 
enemies[1].getHP(); // Do nothing... 
enemies[1].getATK(); // Do nothing... 
enemies[2] = new stats(); 
enemies[2] = orc; 
enemies[2].getName(); 
enemies[2].getHP(); 
enemies[2].getATK();

而這僅僅是通過掠中的第一功能，檢查剩下的讓更少的意義。對不起，如果你有更具體的問題，我會很樂意回答。

是的，在我提供的代碼的這一點是當我絕望。不介意這一點，我已經知道這是行不通的。我發現了一個不同的解決方案，即在for循環之後複製並粘貼所有套牌和敵人，以便自動重置。它便宜，但有效。 –
