2. is it possible for object obj1 to be accesible from object obj2 and object obj2 to be accesible form obj1 ??
TIA

At LINE 01 the member variable is being assigned null. Actually you dont get a reference to the object that is created so you cant even test it anyway.
You're creating a B object in the creation expression for a1 so you are just passing a value of null to the constructor - you have no reference to the B object created except through the the A1 objects bb member. But you're still creating a valid B object even though one of its members has a value of null. Look at this code here with comments exlaining what is happening (I commented out the toString methods so you can see that they are different objects being created):

hope that helps
