Java Installation and Object-Oriented Programming

To start Java programming, you first need two different pieces of software. First, you need the Java Development Kit (JDK), and then you need to find an Integrated Development Environment (IDE). You can choose any IDE you like as there are several options. Once you have an IDE installed, you can start programming! There are several websites with instructions to follow, or you can head to YouTube to find some basic instructions. 

There are four basic concepts and features to object-oriented programming. First, encapsulation is a concept where all objects keep their states private within a class. Abstraction is a concept where you hide all the details or internal workings and only show users what they need to see. Inheritance is a concept where you build new objects and classes based on preexisting objects and classes. Lastly, polymorphism is a concept where a single action can be performed in several ways.
