Java is a high-level programming language, it means that we don't need to know the internals of the language and how it works under the hood to be a Java developer.

I have recorded a series of videos showing essential parts of Java that you need to know to call yourself a senior Java developer.

Introduction

Java development environment

Packaging strategy

Process vs threads
