Tell me something about OOPs
Core Java2017-06-13 08:25:45

Ans. OOPs or Object Oriented Programming is a Programming model which is organized around Objects instead of processes. Instead of a process calling series of processes, this model stresses on communication between objects. Objects that all self sustained, provide security by encapsulating it's members and providing abstracted interfaces over the functions it performs. OOP's facilitate the following features

1. Inheritance for Code Reuse
2. Abstraction for modularity, maintenance and agility
3. Encapsulation for security and protection
4. Polymorphism for flexibility and interfacing

 Q4. While working on a web application, you are informed that there is no new data in Database for last few hours ? How would you go about debugging this problem ?
Solution2018-07-11 10:49:52

Ans. Will look into access logs to see if web application is getting any traffic. If not , then will inform the server support team.

Will look into intermediary infrastructure , queues , streams etc to see if there is any choke or throttle there.

If there is any throttle at any point, would make request for either debugging the cause or increasing the infrastructure. For ex - increasing shards in Kinesis.
