java - How to "save" my program? -
hi guys i'm working on kind of "dungeon crawler" game , need saving program. jframe save(all of entered text)so when close program , open desktop have entered text , have changed still in program. i'm confused how save , hoping help. ahead of time of time, anwsers, links, examples, , advice. clear new , have been coding 5 days , still use netbeans jframe "design" feature generate of code me. below i've posted code second jframe. feel free copy , paste code in netbeans ide. :).
note: in case needing names other jframes. "character" second jframe "mainclass" java app "maingamepanel" third jframe
note:some buttons may not work because not of jframes

another idea create separate class containing information need save. , use class object in main class , save object this.
look serializing class (this called serialization).
public class gamestate implements serializable{ ...//game settings , states stored here } //inside 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();
