hangman游戏尝试替换字母下划线时出错

Question

这就是我得到的错误。我仍在开发它，我只是遇到了一个阻塞点，我尝试在stackoverflow上深入研究它，同时也尝试对它进行切片。我不明白为什么它是一个项目分配，然后我循环的位置，这是一个列表。所以可能是这导致了那个部分，但我需要循环通过它，以得到什么字母位置是正确的，从而改变字符串。我被困了大约两个小时。谢谢

Answer 1

我终于找到了一个成功的例子

尽管看起来很奇怪，但它只在Java GUI应用程序的上下文中工作

因此，简单地扩展JFrame并在单独的线程上启动读卡器捕获似乎就足够了

在我能看到的SDK文档中，这个要求没有具体说明

更新

问题似乎比我最初想象的更严重。不仅必须在Java GUI应用程序的上下文中调用API，而且GUI还必须处于焦点位置，否则捕获调用根本不会返回

我已经用示例SDK应用程序验证了这一点。如果应用程序未处于焦点，则Capture（）方法不会返回。这也适用于C#示例，其中窗口必须处于焦点位置，这表明这是内置于解决方案附带的DLL中的

这对于我们的场景来说很糟糕，我们想要开发一个浏览器可以与之通信的本地服务，因为当浏览器处于焦点时，Java应用程序显然不是
