如何「保存」我的程序？

嗨，大家好我目前正在研究一種「地牢爬行」遊戲，我需要一些幫助來保存我的程序。我想讓我的jFrame保存（我輸入的所有文本），這樣當我關閉程序並從桌面上將其打開時，它將會輸入我輸入的文本以及我在程序中更改的所有內容。我很困惑如何保存和希望得到一些幫助。在此之前感謝您的所有時間，服務員，鏈接，示例和建議。爲了清楚我是新手，現在只有5天左右的編碼，而且我仍然使用Netbeans jFrame的「設計」功能爲我生成大部分代碼。下面我已經發布了我的第二個Jframe的代碼。隨意將這些代碼複製並粘貼到您的netbeans IDE中。謝謝：）。如何「保存」我的程序？

注意：如果需要我的其他Jframes的名稱。「性格」是我第二次的JFrame 「MainClass」是我的Java應用程序「MainGamePanel」是我第三次的JFrame

注意：一些按鈕可能無法工作，因爲這不是我的所有jFrames的

如果它只是文本，將它保存到一個文本文件：http://docs.oracle.com/javase/tutorial/essential/io/。如果它的對象序列化：http://docs.oracle.com/javase/tutorial/jndi/objects/serial.html –

@NicolásCarlo - 它的答案：P – TheLostMind

不要考慮保存幀。考慮保存你的遊戲狀態。例如，選擇一種易於解析的格式，如JSON或XML。 –

xml mabye？
我想你或許可以使用FileOutputStream和PrintWriter創建一個xml文件，其中的數據節點保存遊戲中所有內容的狀態數據。要閱讀它，您可能想要使用Simple API for XML（SAX）。

只是一個想法。

另一個想法是創建一個單獨的類，其中包含您需要保存的所有信息。並將該類用作主類中的對象，然後像這樣保存對象。

看看序列化一個類（這稱爲序列化）。

public class GameState implements Serializable{ 
...//game settings and states stored here 
} 

//inside the main running class 
my_settings = GameState(); 
... 
// write object 
FileOutputStream fos = new FileOutputStream(path..); 
ObjectOutputStream out = new ObjectOutputStream(fos); 
out.writeObject(my_settings); 
out.close(); 
fos.close(); 

//read object 
fis = new FileInputStream(path..); 
ObjectInputStream ois = new ObjectInputStream(fis); 
my_settings = (GameState) ois.readObject(); 
ois.close();
