This week's book giveaway is in the Agile and other Processes forum. We're giving away four copies of The Mikado Method and have Ola Ellnestam and Daniel Brolund on-line! See this thread for details.
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.
