My problem is that I <em>love<\/em> beer. Ok, well that&#8217;s not really my <em>problem<\/em> &#8211; my actual problem is that I love beer so much, that I have a hard time trying to choose which beer I want to drink at any given time. <\/p>\n\n\n\n<p>I mean there&#8217;s just so many to choose from &#8211; IPA, Porter, Stout, Pilsner, Dark Lager, American Sour &#8211; the list goes on&#8230; <\/p>\n\n\n\n<p>So I&#8217;ve decided, I&#8217;m not going to make this decision for myself anymore. Instead, I&#8217;m going to let my assistant choose which beer I want. (Ok, I don&#8217;t actually have my own personal assistant, but just go along with me here on this example). <\/p>\n\n\n\n<p>So I don&#8217;t care which beer my assistant chooses, I just want a beer chosen for me. <\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" width=\"412\" height=\"262\" src=\"http:\/\/pragmaticways.com\/wp-content\/uploads\/2020\/02\/beer-factory-diagram.jpg\" alt=\"Beer Factory Design Pattern Model\" class=\"wp-image-291\" srcset=\"https:\/\/pragmaticways.com\/wp-content\/uploads\/2020\/02\/beer-factory-diagram.jpg 412w, https:\/\/pragmaticways.com\/wp-content\/uploads\/2020\/02\/beer-factory-diagram-300x191.jpg 300w\" sizes=\"(max-width: 412px) 100vw, 412px\" \/><\/figure>\n\n\n\n<p>This is essentially the Factory Design Pattern here. I, the client, need a beer. I don&#8217;t necessarily need to know which beer I get, nor do I need to care about how the beer is made. The only thing I really need to know is that if I order a beer, I&#8217;m expecting <em>some<\/em> type of beer to be returned to me. <\/p>\n\n\n\n<p>My assistant, the beer <strong>Factory<\/strong>, will select one of several different classes of beer, all of which implement a beer <strong>interface<\/strong>. <\/p>\n\n\n\n<p>To get a better representation of this concept, let&#8217;s see what a simple UML diagram for this might look like for this beer scenario:<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" width=\"891\" height=\"222\" src=\"http:\/\/pragmaticways.com\/wp-content\/uploads\/2020\/02\/Beer-Factory-Pattern-UML-Diagram.jpg\" alt=\"A UML Diagram depicting the Factory Design Pattern in the Beer Factory Scenario \" class=\"wp-image-297\" srcset=\"https:\/\/pragmaticways.com\/wp-content\/uploads\/2020\/02\/Beer-Factory-Pattern-UML-Diagram.jpg 891w, https:\/\/pragmaticways.com\/wp-content\/uploads\/2020\/02\/Beer-Factory-Pattern-UML-Diagram-300x75.jpg 300w, https:\/\/pragmaticways.com\/wp-content\/uploads\/2020\/02\/Beer-Factory-Pattern-UML-Diagram-768x191.jpg 768w\" sizes=\"(max-width: 891px) 100vw, 891px\" \/><\/figure>\n\n\n\n<p>Some things may be named a little bit different and in a different order than last time, but it&#8217;s still the same exact concept. We still have 4 main parts here:<\/p>\n\n\n\n<ol><li>The Client (me) &#8211; I order a random beer from the BeerFactory<\/li><li>The BeerFactory (the assistant) &#8211; contains the necessary logic on how to choose a random beer. Perhaps it has logic to choose some type of Ale on Monday, and an IPA on Tuesday. Or perhaps it has logic to select a certain beer based on the hour. Or maybe this beer is for a meal and the type is chosen based on the entree. Whatever that logic is, the client does not need to care. The client just expects a type of beer. <\/li><li>The Beer &#8211; an <strong>abstract class<\/strong> that comes with 5 default steps on brewing a beer. An abstract class cannot be instantiated, but it can be subclassed. Each Beer <strong>Subclass<\/strong> may override this default behavior, but no matter what these 5 steps will be included in every beer type created. <\/li><li>Beer <strong>Subclasses<\/strong> &#8211; The actual beer that gets created. Each beer will have its own special ingredients and may override the 5 brewing steps for their own brew (creation) process.<\/li><\/ol>\n\n\n\n<p class=\"note\">Hey by the way, if you want to learn more about design patterns, I highly recommend you use my affiliate link to get the book Head First Design Patterns.

We will create a very basic Java program around our Random Beer example above to demonstrate the simple Factory Design Pattern. <\/p>\n\n\n\n<p>(And if you don&#8217;t know Java, don&#8217;t worry &#8211; design patterns aren&#8217;t tied to a specific language.

We&#8217;ll start with a Main class to drive our program, and create 2 subclasses that extend a Beer abstract class. Our program will be designed to brew a Stout beer on Mondays, and an IPA beer on any other day of the week.  <\/p>\n\n\n<pre class=\"wp-block-code\" aria-describedby=\"shcb-language-1\" data-shcb-language-name=\"JavaScript\" data-shcb-language-slug=\"javascript\"><div><code lang=\"java\" class=\"hljs language-javascript language-java\"><span class=\"hljs-comment\">\/* Main.java *\/<\/span>\n<span class=\"hljs-keyword\">import<\/span> java.util.Calendar;\npublic <span class=\"hljs-class\"><span class=\"hljs-keyword\">class<\/span> <span class=\"hljs-title\">Main<\/span> <\/span>{\n  public <span class=\"hljs-keyword\">static<\/span> <span class=\"hljs-keyword\">void<\/span> main(<span class=\"hljs-built_in\">String<\/span>[] args) {\n    Calendar calendar = Calendar.getInstance();\n    int day = calendar.get(Calendar.DAY_OF_WEEK);\n    Beer myBeer = <span class=\"hljs-literal\">null<\/span>;\n    <span class=\"hljs-keyword\">if<\/span> (day == calendar.MONDAY) {\n      myBeer = <span class=\"hljs-keyword\">new<\/span> StoutBeer();\n    } <span class=\"hljs-keyword\">else<\/span> {\n      myBeer = <span class=\"hljs-keyword\">new<\/span> IPABeer();\n    }\n    myBeer.brew();\n  }\n}<\/code><\/div><small class=\"shcb-language\" id=\"shcb-language-1\"><span class=\"shcb-language__label\">Code language:<\/span> <span class=\"shcb-language__name\">JavaScript<\/span> <span class=\"shcb-language__paren\">(<\/span><span class=\"shcb-language__slug\">javascript<\/span><span class=\"shcb-language__paren\">)<\/span><\/small><\/pre>\n\n<pre class=\"wp-block-code\" aria-describedby=\"shcb-language-2\" data-shcb-language-name=\"PHP\" data-shcb-language-slug=\"php\"><div><code lang=\"java\" class=\"hljs language-php language-java\"><span class=\"hljs-comment\">\/* Beer.java *\/<\/span>\n<span class=\"hljs-keyword\">public<\/span> <span class=\"hljs-keyword\">abstract<\/span> <span class=\"hljs-class\"><span class=\"hljs-keyword\">class<\/span> <span class=\"hljs-title\">Beer<\/span> <\/span>{\n  <span class=\"hljs-keyword\">public<\/span> <span class=\"hljs-keyword\">abstract<\/span> void malting();\n  <span class=\"hljs-keyword\">public<\/span> <span class=\"hljs-keyword\">abstract<\/span> void steeping();\n  <span class=\"hljs-keyword\">public<\/span> <span class=\"hljs-keyword\">abstract<\/span> void boiling();\n  <span class=\"hljs-keyword\">public<\/span> <span class=\"hljs-keyword\">abstract<\/span> void fermentation();\n  <span class=\"hljs-keyword\">public<\/span> <span class=\"hljs-keyword\">abstract<\/span> void bottling();\n<span class=\"hljs-keyword\">public<\/span> void brew() {\n     malting();\n     steeping();\n     boiling();\n     fermentation();\n     bottling();\n  }\n}<\/code><\/div><small class=\"shcb-language\" id=\"shcb-language-2\"><span class=\"shcb-language__label\">Code language:<\/span> <span class=\"shcb-language__name\">PHP<\/span> <span class=\"shcb-language__paren\">(<\/span><span class=\"shcb-language__slug\">php<\/span><span class=\"shcb-language__paren\">)<\/span><\/small><\/pre>\n\n<pre class=\"wp-block-code\" aria-describedby=\"shcb-language-3\" data-shcb-language-name=\"PHP\" data-shcb-language-slug=\"php\"><div><code lang=\"java\" class=\"hljs language-php language-java\"><span class=\"hljs-comment\">\/* IPABeer.java *\/<\/span>\n<span class=\"hljs-keyword\">public<\/span> <span class=\"hljs-class\"><span class=\"hljs-keyword\">class<\/span> <span class=\"hljs-title\">IPABeer<\/span> <span class=\"hljs-keyword\">extends<\/span> <span class=\"hljs-title\">Beer<\/span> <\/span>{\n  <span class=\"hljs-keyword\">public<\/span> void malting() { System.out.println(<span class=\"hljs-string\">\"Malting with rye grains\"<\/span>);

of writing those functions one line is ONLY meant to save space on this blog. Please follow your style guide, which most likely (hopefully) prevents you from using such convention)<\/p>\n\n\n\n<p class=\"note\">(Also Note: I don&#8217;t actually know how to brew beer, and I did VERY little, although some, research to the steps or variations of steps per types of beer, if applicable. I&#8217;m sorry if I offended any brewers here with this most likely inaccurate information) <\/p>\n\n\n\n<p>Alright, so what&#8217;s wrong with the above code? Well, it violates one core principle to software engineering best practices, the <a href=\"http:\/\/pragmaticways.com\/5-solid-principles-all-software-engineers-need-to-follow\/#Open_Closed_Principle\">Open\/Close Principle<\/a>. <\/p>\n\n\n\n<h4>The Open\/ Closed Principle (OCP)<\/h4>\n\n\n\n<p>The OCP states that software entities should be open for extension, but closed for modification. In the example code above, what happens when we add a new beer type to the equation, say brewing a PorterBeer on Tuesdays. Well we&#8217;d need to open up the Main.java file and <em>modify<\/em> the if-else statements. <\/p>\n\n\n\n<p>Or what if the creation logic needs to completion change or get reworked, again we&#8217;d be violating the Open\/ Closed Principle and not following clean code standards. <\/p>\n\n\n\n<h4>DRY Principle<\/h4>\n\n\n\n<p>You could also make the case that we&#8217;d end up violating the DRY principle at some point, which stands for Don&#8217;t Repeat Yourself. Imagine as this program grows, we may eventually need this functionality or logic to be used in multiple places for multiple different occasions.<\/p>\n\n\n\n<p>With this current approach, we&#8217;d end up having to duplicate this creation logic to many different places. What a maintenance nightmare! <\/p>\n\n\n\n<p>So let&#8217;s see how we can fix this code with the use of the Factory Design Pattern. <\/p>\n\n\n\n<h3>Creating the BeerFactory<\/h3>\n\n\n\n<p>First, let&#8217;s start by creating the BeerFactory. We&#8217;re going to strip out any functionality from our Main class that relates to the creation of a Beer. <\/p>\n\n\n<pre class=\"wp-block-code\" aria-describedby=\"shcb-language-5\" data-shcb-language-name=\"PHP\" data-shcb-language-slug=\"php\"><div><code lang=\"java\" class=\"hljs language-php language-java\"><span class=\"hljs-comment\">\/* BeerFactory.java *\/<\/span>\nimport java.util.Calendar;\n<span class=\"hljs-keyword\">public<\/span> <span class=\"hljs-class\"><span class=\"hljs-keyword\">class<\/span> <span class=\"hljs-title\">BeerFactory<\/span> <\/span>{\n  <span class=\"hljs-keyword\">public<\/span> Beer getBeer() {\n    Calendar calendar = Calendar.getInstance();\n    int day = calendar.get(Calendar.DAY_OF_WEEK);\n    <span class=\"hljs-keyword\">if<\/span> (day == calendar.MONDAY) {\n      <span class=\"hljs-keyword\">return<\/span> <span class=\"hljs-keyword\">new<\/span> StoutBeer();\n    } <span class=\"hljs-keyword\">else<\/span> {\n      <span class=\"hljs-keyword\">return<\/span> <span class=\"hljs-keyword\">new<\/span> IPABeer();\n    }\n  }\n}<\/code><\/div><small class=\"shcb-language\" id=\"shcb-language-5\"><span class=\"shcb-language__label\">Code language:<\/span> <span class=\"shcb-language__name\">PHP<\/span> <span class=\"shcb-language__paren\">(<\/span><span class=\"shcb-language__slug\">php<\/span><span class=\"shcb-language__paren\">)<\/span><\/small><\/pre>\n\n\n<p>Now, all we need to do is to update our Main class to use the BeerFactory. <\/p>\n\n\n<pre class=\"wp-block-code\" aria-describedby=\"shcb-language-6\" data-shcb-language-name=\"PHP\" data-shcb-language-slug=\"php\"><div><code lang=\"java\" class=\"hljs language-php language-java\"><span class=\"hljs-comment\">\/* Main.java *\/<\/span>\n<span class=\"hljs-keyword\">public<\/span> <span class=\"hljs-class\"><span class=\"hljs-keyword\">class<\/span> <span class=\"hljs-title\">Main<\/span> <\/span>{\n  <span class=\"hljs-keyword\">public<\/span> <span class=\"hljs-keyword\">static<\/span> void main(String[] args) {\n    BeerFactory beerFactory = <span class=\"hljs-keyword\">new<\/span> BeerFactory();\n    Beer myBeer = beerFactory.getBeer();\n    myBeer.brew()&lt;code&gt;;&lt;\/code&gt;\n  }\n}<\/code><\/div><small class=\"shcb-language\" id=\"shcb-language-6\"><span class=\"shcb-language__label\">Code language:<\/span> <span class=\"shcb-language__name\">PHP<\/span> <span class=\"shcb-language__paren\">(<\/span><span class=\"shcb-language__slug\">php<\/span><span class=\"shcb-language__paren\">)<\/span><\/small><\/pre>\n\n\n<p>Wow! Look at how much cleaner our Main class is now! We removed all the unnecessary logic behind what goes into choosing which beer to brew and isolated it to its own Factory. <\/p>\n\n\n\n<h3>When to use the Factory Design Pattern?<\/h3>\n\n\n\n<p>The Factory Design Pattern allows you to separate the object construction code from the code that actually uses the object. This makes it easier to extend the object construction code, independently from the rest of the code!<\/p>\n\n\n\n<p><strong>Use the Factory Pattern when:<\/strong><\/p>\n\n\n\n<ul><li>you don&#8217;t know ahead of time what class object you might need<\/li><li>you don&#8217;t want the client to know <em>every<\/em> type of possible subclass<\/li><li>you want to centralize class selection<\/li><li>you want to encapsulate object creation<\/li><li>all the possible classes inherit from a common super class<\/li><\/ul>\n\n\n\n<p class=\"note\">If you want to learn more about design patterns, I highly recommend you use my affiliate link to get the book Head First Design Patterns.
