-'''Object Oriented programming '''(OOP) languages are based around the paradigm of objects that interact with each other to produce functionality. There are many [[programming language|programming languages]] that are designed around object oriented principles, such as [[Java]].
-== Objects ==
-Objects are components of an object oriented language, consisting of properties and methods.
-An object is also known as a Type or Class.
-== Polymorphism ==
-Polymorphism allows an object to appear as another object. This means that a complex object can appear to be a simple one. The example below shows that you can have a specific model of car, such as the [[Model T]], which looks like and acts like a normal car.
-=== Example ===
-<pre>
-public class ModelT extends Car {
-    private Color color = Color.BLACK;
-    private String model = "T";
-    public void setColor(Color color){
-        this.color = color;
-    }
      public Color getColor(){
