將文本字段添加到程序中

Question

我正在爲我提供一個更好的應用程序版本。我仍然需要與給予我的程序相同的組件，我只需要重新組織它。我還被告知不要複製任何原始代碼並從頭開始。第一個屏幕截圖顯示了我需要從原始程序添加到我的程序中的文本框。第二個截圖是我的程序。我不確定JTextField是否適合這一點。我的代碼如下。我試圖用JLabel添加JTextField並居中，但是當我運行該程序時，它覆蓋了程序中的所有其他內容，只顯示一個小小的白色框。

Answer 1

去JTextArea

JTextArea是一個顯示純文本的多行區域。

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

對於所需的佈局是指Layout Manager by Oracle
