I am having an option to gray out all the components in a panel, if the FTP service is not running.I am able to gray out all the components in the panel except the table in the panel. I used setEnabled(false), for all these components, but doesn't seem to be working with table.Table still shows to be an active component.Can somebody help me so that I can give this table a grayed out look? The table is put in a scroll pane, i am disabling scrollpane too.
I have just started the preparations for SCWCD.My doubt is about Apache Tomcat.Is it a web container or a server?In some places I see that Apache is a web server, and that Tomcat is a web container?So I am confused, about this container and server terminology.
Thanks, my issue got fixed after I upgraded to java version "1.6.0_03".
I am not sure, but I think in the beta version, @Override annotation was not compiling while used with implementing an interface.It worked fine when I tried to extend one class.
I've implemented an interface to a class and use @Override for the implemented methods.But while compiling i get error saying "Method has to override a method from superclass". Can @Override be used just while extending classes or implementing interfaces too?
Well, I am a bit confused about how many minimum number of objects are needed for IS-A and HAS-A relationships? I thought HAS-A needs only one since a class can have its own instance.But then what about IS-A?(Object IS-A Object too, right?)
Originally posted by Barry Gaunt: It is trivial to create an instance of Cricket and assign it to references of types Game and Playable. Then you can call the method via both of those references to see what happens.
Thanks Barry, because I too was having this doubt. So ,if I am not wrong, our conclusion is that will invoke the abstract class version. will invoke the interface version. Right?
