Hi,
I came with a very basic question about swing component. Could
anybody clear it out?
Sometimes i find class instance in both way.

label = new JLabel("Click.", JLabel.CENTER); // 1st statem
Jlabel label = new JLabel("Click.", JLabel.CENTER); // 2nd statem
In the 2nd statement, i am instantiating and intialising
Jlabel constructor as label and a copy of reference to
the Jlabel Object, isn't it?.
My question is that why sometimes we use the 1st statement to
give a same effect instead of second. In the 1st statement
there is no Jlabel Object?
Do appreciate if you clarify that.
Thanks,
Golam Newaz

You must have created the container for the variable earlier in the program.
Campfire Stories has an amusing story which reviews how variables are created and initialized: http://www.javaranch.com/campfire/StoryCups.jsp

Thanks a lot for providing an amazing page my dear pal, Cindy.
Now almost clear about OO language. Javaranch.com is our
object. You were controlling with one remote control and
when i asked help you gave me a copy of your remote control (
a copy of reference ) but javaranch.com object is same,
when your location (name of reference ) and my location is different,isn't it?
Thanks a lot,
Golam Newaz.
