Many of the most used programming languages today, including Java, are object oriented. This means that programmers can organize their code in a specific way that makes it easy modify and use in lots of different ways. To understand why object oriented programming is so useful, I will first explain what classes and objects are, then we will look at a few examples of how they can be used.

What are Classes and Objects?
A class is a blueprint of code that can be copied over and over in your program. Each copy of a class that gets created when a program runs is called an object.

A programmer usually writes a class to do something that is a little bit different in different circumstances. Lets look at an example of how a programmer could use classes and objects to write a program that keeps track of sales at a lemonade stand.

In this example, the programmer has written a class called 'Drink'. This class has the blueprint to store information like Flavor, size, ice, and price. In the program, the programmer has created two objects, lemonade1 and lemonade2, that follow the pattern of the class. The two objects follow the same pattern but they are different in the specific information they contain. This makes an easy way to log a new purchase every time the lemonade stand has a customer. The user just has to enter in the flavor, size, weather the drink had ice, and the price. Then the program make a Drink object and store it in a list.

Later on, if the user wants to see how much money they made, they just have to add up the price variable from all the Drink objects in the list. If they want to see which flavor was most popular, they can count up the number of each flavor from the list of Drink objects. This class and object system makes it really easy to organize all this information.\n
