Generic method

[jomypgeorge]

is there any way to make a new instance of generic type in a generic method?
some thing like

<T> void receive(List <T> a)
	{
	a.add(new <T>());
	}

or is it foolish to make a new instance while we don't know what is the type of that instance at run time?

Hi.
You can't create new instance from generic type, because may be situation when generic type may be have no public constructors.

thanks petr,

also we cant assure that the generic type have a constructor of the type we use

[Petr]

However, I read about this problem. You can use (Class<E> clazz).newInstance();,
but it makes no sense.

[jomypgeorge]

think its using reflection ...
right?

[Petr]

Yes,it is. This is reflection.
I don't understand why do you want to do this? Why do you want to use this code?

[jomypgeorge]

i don't want to use it in actual code, but now i am learning generics in java and try to experiment with that.

thanks petr for quick reply
