Java learning path

This is the repository dedicated to Java learning. I am going to keep track of my progress here using variety of options, including books/courses listing and so on.

Actually, the only and one reason for me doing this is organizing my learning routine as well as keeping everything in a single place that can possibly be shared with anyone else.

If you are passionate about learning any programming language, and need a tool to organize things up, I would be more than glad to know that my example helped and inspired you.

Theory

There are items I need to learn better and some are already learnt:

  • Language Basics (Data types, Exception handling, I/O, Stream API, etc... )
  • Wildcard, Generics & Collections
  • Data structures, Algorithms, Algorithmic complexity
  • Data Access
  • Basic understanding of threading and concurrency
  • Basic design patterns like singleton, factory, etc.
  • Class Design & OOP Principles
  • Architecture
  • Threads & Concurrency
  • Tools & Other Standard Libraries
  • Web Services
  • Web Components
  • Swing, AWT & JAVAFX
  • Hibernate
  • Spring
  • EJB
  • JPA
  • JDBC
  • (to be completed...)

Non-Java related (generic things)

List of websites which I use to find the tasks:

  1. Codewars
  2. Codingbat
  3. Hackerrank
  4. Codesignal (ex-CodeFights)
  5. Codingame
  6. ...

My rules:

It is better to do it less hard but regularly, so here's the basic rules on how to quickly achieve the goal

  1. Pick up a course (see table below), keep walking with it regularly - ONE COURSER AT TIME
  2. Solve at least three tasks from Codingbat
  3. Keep reading the book of your choice (see table below), don't ignore the practicing

Other cool stuff

Interesting challenges to solve:

Practice

Here goes a list of tasks solved for some particular amount of time. I started logging them from April 2018, but there are a lot of untracked tasks and katas (referring to Codewars) which I solved a long ago before that.
