COLLECTIONS

Collections are the data structures that are basic building blocks to create any production level software application in Java. Interviewers are interested in understanding different design aspects related to the correct usage of collections. Each collection implementation is written and optimized for a specific type of requirement, and interview questions are to gauge the interviewee's understanding of such aspects.

Following are few aspects on which questions on collections are asked:

Collection types in Java.
