Disadvantage of encapsulation

[saneha]

Hiding of implementation makes it easier to carry out ones task but does not it make one loose total grip on to the program? Kindly clear this confusion. Thanks

Hiding Implementation detail from “real users”/ customers/ clients rather than Programmers. A car driver doesn’t need to know the internal manufacturing details as it creates complexity. Similarly, the real end users of the system/application needs not to know internal application details, he/she just concerns whether the required functionality has been developed or not?

So, basic idea is to cope with complexity.
