The difference between Classes, Objects, and Instances

Question

What is a class, an object and an instance in Java?

Answer 1

The concept behind classes and objects is to encapsulate logic into single programming unit. Classes are the blueprints of which objects are created.

Here an example of a class representing a Car:

public class Car {

    int currentSpeed;
    String name;

    public void accelerate() {  
    }

    public void park() {
    }

    public void printCurrentSpeed() {
    }
}

You can create instances of the object Car like this:

Car audi = new Car();
Car toyota = new Car();

I have taken the example from this tutorial
