Java Interview Topics

Here’s a list of common topics I’ve encountered on technical interviews pertaining to Java:

• inheritance
• polymorphism
• multi-threading (locks)
• interfaces
• pass by reference/pass by value/pass by pointer
• data structures/algorithms – eg: return top N duplicate results from large data set
• set vs list
• object vs non-object data types
• internationalization – eg: utf-8 vs utf-16

It is a good idea to be prepared to discuss as many of these as you have experience with.
