JFrame and JOptionPane

Question

I have been messing around for a bit now to get this to work how I intend it to work, but couldn't find anything through Google or API to find the answer I seek, so here I am!

The project I am currently working on is an App for soldier registration (Theme of project), I used JFrame and JButton s, but I need to get a dialog box in JFrame that will intake answers. Something that works like this, but is integrated in JFrame :

nameField = JOptionPane.showInputDialog(null, "Enter Username(Default is 000000");

Answer 1

好吧，通过集成到JFrame中，我不太确定你想要对话框做什么，但只需将JOptionPane.showInputDialog()的第一个参数设置为父框架，输入就会有父窗口的图标。

nameField = JOptionPane.showInputDialog(myParentFrame,"Enter Username(Default is 000000");
