Is this scenario is possible that I have a java class and its object is created by java applet at run time means that when I call the applet it will be mapped by the java class and its object is get created at runtime..any framework that support this kind of requirement..?
The title is vacuous, because objects only get created at run-time. There is no other time at which objects are created.
And generally you don't need a framework to create an object. The "new" keyword should suffice in most cases. But I'm sure you already knew about the "new" keyword, so perhaps you could explain your mysterious requirement for which it isn't good enough?
