Memory Layout of Java Objects vis-a-vis Inheritance...

These two diagrams describe the memory layout of Java objects. This is with respect to inheritance and not from padding bits or alignment's point of view. To make it simple, i have omitted the methods from the Object class (the root class) in the VTBLE (also called method table). They will obviously occupy the first few indexes in each VTBLE in Java as all the classes are naturally derived from the Object class.
