Hi 1. I want to know why java doesnt support multiple inheritance ? what is the difference between multiple n multi level inheritance? 2. what is the advantage of swing over other user interface?
With refrence to your question about multiple inheretence, I suppose u could say that there are cases where multiple inheritence can cause problems. Consider the case where u inheret from the same class twice in this case the methods inhereted from the parent class will be overloaded and it will not be clear as to which method is being called. though you could implement multiple in heretence in the child class using containment by creating handles to the parents(source)and then overloading the desired methods by dummy methods which call the parent class method using the handle u created. hope this helps.
Two unrelated questions would work better in two separate posts - the converstion is less confusing that way. But anyway, to answer your second question: What other user interface are you considering? Swing and awt are the only ones available in Java, so their big advantage over other interfaces is: they work in Java, and you get all the advangtages that Java offers. If you're asking why is swing better than awt - basically, swing has a lot more options. Further details are possible if you clarify your question.
