I'll be the first to admit Java can be very verbose, but I don't think this is unreasonable:
JOptionPane.showMessageDialog(null, "My Goodness, this is so concise");
If you statically import javax.swing.JOptionPane.showMessageDialog
using:
import static javax.swing.JOptionPane.showMessageDialog;
This further reduces to
showMessageDialog(null, "This is even shorter");
