jToggleButton的while循环错误：JAVA

我在netbeans中编写了一个用于音频捕获的函数。但是while循环代码中的最后一个花括号显示了编译错误，我不知道为什么代码中会通过注释提到这一行。不管怎样，我运行这个项目，它说编译时出错，然后运行。运行该应用程序后，我单击jToggle按钮启动编码的功能音频捕获，它成功地工作了。再次单击jToggleButton停止FunctionalUDIO捕获后，它也会停止。但在第二次单击之后，netbeans输出终端也会显示一些错误。所以，我试图找出问题所在，但仍然无法确定代码出了什么问题。我希望，我能从这里得到帮助

错误日志：

代码：

---

//此卡利括号显示红色下划线。但我不知道为什么

读取编译器错误，它表示用关闭此语句

因为您尚未关闭以下语句：

 Thread t = new Thread ( new Runnable()

此错误表示您的声音库无法处理声音文件的格式。您需要添加；在带下划线的括号后面合上新线谢谢@killedbycese。我得到了它。现在这个错误被修正了。但netbeans输出终端显示的问题中提到的错误仍然存在。你能帮我吗。。。？我试过了，但还是不知道。你好@SteveSmith，那我怎样才能修复它。。。？你能帮我吗？@user7560586不要删除原始问题中得到回答的部分，如果问题已经解决，请接受回答。因为其他人将来可能会提到它。非常感谢@Rohit Gulati，我明白了。现在这个错误被修正了。但netbeans输出终端显示的问题中提到的错误仍然存在。你能帮我吗。。。？我试过了，但还是不知道。@user7560586您能试试这个吗？因为上面提到的问题是完全相同的。@user7560586正如上面链接中提到的，您在代码中打开了两行。当您试图打开第二个时，第一个的存在会阻止它。麦克风.openformat；和speakers.openformat@User7560586我对此也不熟悉，但我尝试运行您的代码，当我注释掉代码micromic.openformat时，它现在抛出了expetion。试图只打开一行。执行此操作后，检查您的功能是否按预期工作。
