Java 如何"；“保存”；我的节目？
嗨，伙计们，我目前正在开发一种“地牢爬虫”游戏，我需要一些帮助来保存我的程序。我想让我的jFrame保存（我输入的所有文本），这样当我关闭程序并从桌面打开它时，程序中仍会有我输入的文本和我更改的所有内容。我不知道该如何储蓄，希望能得到一些帮助。提前感谢您的所有时间、留言、链接、示例和建议。要明确的是，我是新手，现在只编写了大约5天的代码，我仍然使用Netbeans jFrame“设计”功能为我生成大部分代码。下面我发布了我的第二个Jframe的代码。请在您的netbeans IDE中复制并粘贴此代码。谢谢：） 注意：以防需要我的其他JFrame的名称。 “角色”是我的第二个jFrame “MainClass”是我的java应用程序 “MainGamePanel”是我的第三个JFrame 注意：有些按钮可能不起作用，因为这不是我所有的jFramesJava 如何"；“保存”；我的节目？,java,swing,netbeans,Java,Swing,Netbeans,嗨，伙计们，我目前正在开发一种“地牢爬虫”游戏，我需要一些帮助来保存我的程序。我想让我的jFrame保存（我输入的所有文本），这样当我关闭程序并从桌面打开它时，程序中仍会有我输入的文本和我更改的所有内容。我不知道该如何储蓄，希望能得到一些帮助。提前感谢您的所有时间、留言、链接、示例和建议。要明确的是，我是新手，现在只编写了大约5天的代码，我仍然使用Netbeans jFrame“设计”功能为我生成大部分代码。下面我发布了我的第二个Jframe的代码。请在您的netbeans IDE中复制并粘贴此
