进入您的JumpHosts
构造函数：
JumpHosts（TextPanel TextPanel 1，TextPanel TextPanel 2）
能够引用与大型机相同的文本面板
对后续行动的答复：
您需要首先将TextPanel
传递给FormPanel
构造函数，从MainFrame
构造函数开始。然后，您需要修改FormPanel
构造函数，将TextPanel
传递给JumpHosts
构造函数。删除所有出现的static>一词
从您的TextPanel类。而不是TextPanel.appendText
，在TextPanel的特定实例上调用该方法。@VGR我已将all设置为非静态并更新了代码。请参考更新的代码。但现在我在文本区域中根本看不到任何输出。我在代码中没有看到对appendText
的任何调用（除了附近的隔离代码行）
