Java 在jtextfield中逐个显示数据，而不是一次显示所有数据

下面是代码。它从com端口读取数据，并在netbeans gui创建的文本字段中显示数据。这段代码运行。它实际上合并了5个com数据，并在最后一次显示出来

我想在gui中逐个显示单个数据。在程序结束时，并非所有5个数据都在一起。实际上，我希望gui将运行，然后文本字段填充从com端口读取的5个数据

试试这样，我没有做太多的更改，只是创建了一个线程。

在一个单独的线程中读取和附加这些内容，你认为这样行吗？我需要先显示GUI。然后在textfield上附加com数据。使用此当前代码组合方法，首先执行excute，然后将所有数据一起显示。可能您必须使用字符串缓冲区将每个读取的字符串与新行运算符连接起来，然后将其附加到jTextArea1？我有一个印象，读取的字符串是作为一个长字符串生成的，所有的值都在一起，或者你可以根据一些特定的字符分割这个字符串。错误是找不到适合线程的构造函数。任何解决方案。我创建线程。现在的问题是gui正在运行。但是GUI中没有数据。覆盖运行函数不运行。您启动了线程，但运行不起作用？尝试在运行方法中打印一些东西！
