Java Classes and Objects Tutorial for Beginners. Learn how to create and use Classes in Java programming Language.

Welcome everyone to Java Coding Community. In today's tutorial I will be explaining the basics of Object Oriented Programming in Java. Introduction to Classes and Objects and also explaining the private and public keywords. So lets just right into it.

A class is a collection of
• fields – if you are new to Java, fields are similar to variables – and those fields hold some data
• And methods that work with those values
The most important thing to know is that they define a new data type – this might be confusing but yes, in Object Oriented Programming you can create your own Data Types.

So, a class is a Data Type, but the Class Object is it's value.

So a class is like a blueprint, in it you create a model. An instance of that blueprint is called an object.

Let's demonstrate this on an example. We will be modeling a Car.
