I have developed an Applet(600 X 400) which is used a Network Management tool. I developed this using java1.5.
I have got into a serious issue. which is ...
a)Open the applet in a IE 6 window. b)resize it to a size less than the maximum size. c)Move up and down scroll bar of the browser(it has scrollbar). d)we can see the applet flickering.
* Use interface if you don't want to implement any of the member functions. This implies. - The class implementing the interface must implement all of its functions.
* In abstract class you need not define/implement all the functions like interface. This can be used where you can to define/implement some method and allow user to implement the rest(if there any unimplemented funtions..since there an abstract class can define/implement all the functions).
Interface and abstract class can be used for multiple inhertence. (OOP concept)
