RFE: Need showMessageDialog with only one parameter in javax.swing.JOptionPane

Name: jk109818 Date: 12/05/2002


FULL PRODUCT VERSION :
J2SE 1.4.1_01

OPERATING SYSTEM VERSION :
ANY VERSION


A DESCRIPTION OF THE PROBLEM :
Please overload showMessageDialog in javax.swing.JOptionPane
to be able to use this method with only one parameter when
no frame is open.
This would allow to write :
javax.swing.JOptionPane.showMessageDialog ("Hello");
instead of :
javax.swing.JOptionPane.showMessageDialog (null, "Hello");
avoiding the null default parameter.

This RFE aims to help Java teachers to use the
showMessageDialog method instead of the classic
System.out.println method for the following reasons :
1. java.lang.System.out.println doesn't display correctly
Unicode international characters in DOS command windows
2. javax.swing.JOptionPane.showMessageDialog is longer to
write but is more simple to explain (you can just say "call
the class method showMessageDialog of
javax.swing.JOptionPane class"). But the null parameter is
often forgotten by students and is difficult to explain to
beginners.
3. javax.swing.JOptionPane.showMessageDialog is really
helpful to display all kind of things.
4. javax.swing.JOptionPane.showInputDialog exists with one
parameter so why not doing it with showMessageDialog ?
5. It will take 1 minute to any Sun developer to program it...

REPRODUCIBILITY :
This bug can be reproduced always.
