Difference between Primitive types and Objects

Primitive Types:

• Primitives types are loaded in stack.
• When the primitive is assigned to another primitive type copy is created.
• Primitive types are not polymorphic, so it cannot be passed as to a method that takes object as a parameter.

Objects:

• Objects are loaded in heap
• When object reference is assigned to another object reference,they share the same object
• Objects are Polymorphic, so they can be passed as a parameter to any method that takes object as parameter.
