Classes:

• Java is an object-oriented language
• Its constructs represent concepts from the real world.
• Each Java program has at least one class that knows how to do certain actions or has properties
• Classes in Java may have methods and properties (a.k.a. attributes or fields)

                                            Example 1: Car Class

Example 2: Creating Car Objects

Now the variables car1 and car2 represent new instances of Car:

car1.color=“blue”; car2.color=“red”;!

These two Car instances are created with the new operator:

 Car car1 = new Car();

Car car2 = new Car();

Go!
