java message box

[308holes]

is thier a messagebox in java like in vb ????? if so how do i use it ?

There is a message box method in Java, however it is only available when using Swing (I think).

Swing allows you to use graphical components in Java classes. If you want to know more about this goto:

http://java.sun.com/docs/books/tutorial/uiswing/

It's a Swing tutorial. However, if you are just doing it for debugging etc. I suggest ignoring it as it can be very slow. Also, it's rather a lot of possibly unnecessary hassle.

Hope it helps

ok cool thanks for the tutorial but dose it have a name so can search for it ?

[HairyDave]

Sorry I forgot to say what the thing's called

You can use the JOptionPane class (I think) and the method showMessageDialog(...). Have a look here:

That should do it!

[HairyDave]

Can't be sure if this will work - don't have chance to try it (supposed to be working )


/* All imports here - java.swing.* and the like
*
..
*/

JFrame frame = new JFrame("My Window");
JOptionPane.showMessageDialog(frame, "This is my window");



http://java.sun.com/docs/books/tutor...ialogDemo.java

is an example of using frames and dialogs with Swing.

I've not done much so I haven't got any examples.
