Overview of JAVA

As we all know java is object-oriented.

What do you mean by Object-oriented?

Well, Object-oriented means, everything we deal with, in java is basically an object.
When we get into the later topics you will understand the power of objects.

What is an Object?

Object is an instance of class. In objected oriented programming languages as in java this concept is mainly taken from the concept real world concepts. For example in the world we may have several cars(BMW, suzuki, audi..) but we represent the whole cars as a single class and when we come to any particular car brand we assign a brand name for that. This is similar Class and Object paradigms in JAVA.
