There is no such thing as Core java. It’s just a title of a book and that’s about it
Expertise in any particular field or subject takes in enormous effort and patience. so if you are planning to learn Java for getting a Job then you’ve got to cover the fundamentals pretty good. And that’s about it. Rest you could learn on the fly while working.
When I say fundamentals what do I refer to its properties and behavior of:
- Objects
- Variables
- Functions
- Classes
- Collections
- Data Types
Imagine having 10 or more years of experience and yet all along the while, you failed to have a basic understanding of object creation or deletion in Java. So, worthless right.. ?
Then, the logical step is to learn Object Oriented Principles of Java:
- Data Abstraction
- Encapsulation
- Polymorphism
- Inheritance
After you are done with this, start by going through some really beautiful concepts like:
- Multithreading
- Generics
After you are done with this….
Just Stop !! Try and re-learn everything.
