这是我的 Windows 课程 ^^
这是程序的样子 http://puu.sh/2kvpt

底部的文本框是我正在谈论的文本框

好的，所以这是我的问题，我正在尝试将我的整个程序转换为在 GUI 上显示，我对此非常感兴趣。但我不知道如何使底部文本框作为 System.in 工作以使扫描仪工作。我怎样才能做到这一点？谢谢！9错误的代码格式来自 4spaces stuff OO)

不要使用 awt 组件（已弃用）。更喜欢使用 Swing 等效项：JTextArea

见http://docs.oracle.com/javase/1.4.2/docs/api/javax/swing/JTextArea.html

然后，您可能会找到一个 getText() 方法
