Gain insights into Java programming by exploring conditional statements, loops, math, logic, inheritance, generics, and arraylists, to become an intermediate Java developer.

Learn Java for free with this interactive course, and get a handle on one of the most popular programming languages in the world.

You'll start with a simple hello world program and proceed to cover common concepts such as Conditional Statements, Loop Statements, Math, and Logic in Java, before moving on to more advanced concepts like Inheritance, Generics, and ArrayLists, along with much more.

By the time you're done, you'll be an intermediate level Java developer, ready to take on your own projects.

# Definition
`Classes` are the building blocks of programs built using the object-oriented methodology. Objects have certain similar traits - state and behavior. This commonality is provided in a blueprint or template for the instantiation of all similar objects. This blueprint is known as a *class*.


class className {

  int integer_one;
  String string_one;

}

A *Keyword* `class` is used with every *declaration* of class followed by the name of the class. You can use any *className* as you want. 

# Fundamentals

Every class in Java can be composed of the following elements:

* `fields, member variables or instance variables` - These are variables that hold data specific to a particular object. For each object of a class, there is one field. 

* `member methods or instance methods` - These perform operations on objects and are defined within the class.

* `static or class fields` - These fields are common to any object within the same class. They can only exist once in the class irrespective of the total number of objects in the class.

* `static or class methods` -  These methods do not affect a specific object in the class.

* `inner classes` -  At times a class will be defined within a class if it is a subset of another class. The class contained within another is the **inner** class.

Now that we understand these basic concepts within classes, let's look at an example of a class and see if we can understand them better. 

In this lesson, an explanation of the basics about classes in Java- what are they and how to define them is provided.
