How do I create a Java messagebox an on form messagebox? Stuck

I know how to create a regular popup messagebox as below:

JOptionPane.showMessageDialog(this, "Couldn't log in");

But I don't know how to create one as below, I'm stuck on how we create this sort of messagebox..

You need to make a custom dialog.
Look at the tutorial: http://docs.oracle.com/javase/tutori...ts/dialog.html
