Match the following with reference to object oriented modelling : Codes :List - I List - II (a) Polymorphism (i) Picking both operator and attributes with operations appropriate to model an object (b) Inheritance (ii) Hiding implementation details of methods from users of objects (c) Encapsulation (iii) Using similar operations to do similar things (d) Abstraction (iv) Create new classes from existing class
| a | b | c | d |
| (iii) | (iv) | (i) | (ii) |
Polymorphism lets similar operations be invoked the same way on different objects, so (a) - (iii); inheritance creates new classes from existing ones, so (b) - (iv).
Encapsulation bundles the attributes together with the operations that act on them into one unit, so (c) - (i).
Abstraction presents only what an object does and hides how its methods work, so (d) - (ii).
Only one code pairs (a) with (iii) and (b) with (iv) together.
Hence, a - iii, b - iv, c - i, d - ii.
