我目前正在开发Java应用程序，我正在使用JFrame，在JFrame内部我有一些按钮、标签和文本字段。我需要隐藏JFrame中的所有元素。我不需要隐藏JFrame本身，只需要隐藏其中的元素，这样我就可以显示其他元素。有没有一种方法可以在不手动编写元素的情况下将它们全部隐藏起来。setVisibility(false(；他们每一个人？

我认为这做不到。。。
实际上，我认为会的，但是，您缺少了一些非常重要的核心概念。
解除耦合
您正在使用OO语言进行操作，您将要关注的一件事是"；去耦"；您的功能与其他功能的依赖关系。问问自己这个简单的问题。如果我必须修改系统的这一部分，它会产生什么后果。如果你发现自己处于一系列变化中，那么你的系统就是紧密耦合的
单一责任
你想尽可能地隔离功能，这样它就只有一项工作要做；上帝；类(就像你所拥有的(，它试图做所有的事情，将你的问题分解成小块，并隔离功能，这样它就可以做尽可能简单的工作。
尽可能地，每个元素都不应该依赖于了解系统的当前状态，而不仅仅是被告知的情况，这是第一点和第三点的一部分。
依赖项注入
将每个子系统需要的信息传递给他们，而不是拥有全局可访问的资源。这对测试来说确实很好，但它进一步减少了耦合
接口代码
使用interface来描述高级功能概念。例如；学生详细信息"；view并不关心学生信息是如何构建、获取或管理的，它只关心呈现interface(或合同(维护的一些信息。这将使对底层实现进行核心更改变得更容易，而不会对想要使用它的系统的所有部分产生不利影响，因为它们只依赖于"；合同；由interface定义
示例
现在，我通常使用CardLayout，但CardLayout并不像这个问题可能需要的那样动态。
所以，相反，我推出了自己的"；导航"；工作流。这使我能够更好地控制需要注入的信息，并允许更动态的演示-当学生注销时，你不想在学生登录屏幕上显示学生凭据。
