(First time using this so forgive me if I am doing anything wrong)
I have an upcoming interview for Java Software Engineer position and my recruiter told me to “brush up on core Java.” I finished taking the learn java courses and it helped so much. I have a much better understanding of OOP and hashmaps. But I feel that this might not be enough, I feel that I need to learn better about stuff like Linked List, bubble sorting, polymorphism, stacks and queues, recursion, and anything else associated with data structures and algorithms.
Am I misunderstanding what core java means or do I need to learn more of the concepts I just mentioned? if so…
I dont see these advanced stuff here in code academy, does anyone have a resource for another online interactive platform that is as good as code academy that can help me better learn this stuff?
Thank you everyone
