Java Object Oriented Programming for Beginners

I have a master's degree in computer science and have been lecturing for more than nine years. I have enough experience in Application Development, Database design and developing complex systems like Student information management system.
In this lesson I will lecturing and tutoring students starting from describing basic concept of object-oriented programming and at the final we will automate one system using Java.
Object-oriented programming (OOP) is a fundamental programming paradigm based on the concept of “objects”. These objects can contain data in the form of fields (often known as attributes or properties) and code in the form of procedures (often known as methods).
The core concept of the object-oriented approach is to break complex problems into smaller objects.
In this lesson, we will be looking at the following OOP concepts:
 What is Java?
 What is a class?
 What is an object?
 What is a Java Virtual Machine (JVM)?
 How access modifiers work in Java.
 How constructors work in Java.
 How methods work in Java.
 Key principles of OOP.
 Interfaces in Java.
