I should have stated it clearly ..
i actually meant passing type Class in constructor itself like in following
code:-
class Funny {
private ClasstypeClass;
public Funny(ClasstypeClass){
this.typeClass=typeClass;
}
}
class Funnier extends Funny{
private ClasstypeClassT;
private ClasstypeClassR;
2, 47), instance);

a bit about what is actually in the bytecode and contradicts (as
conclusively as using javap) what some would have you believe.

what happens if down the line the index of the type changes?: )

the first time I used genericsuperclass() was in generic daos after
reading https://www.hibernate.org/328.html,
though it has it's own quirks, it doesn't apply every where ..
abstract modifier in above code was needed,it's done so that one will
eventually subclass funnyfactory

At the risk of reigniting the world-famous generics debates of yesteryear, just as our noble core-developers regroup to start work on mak
