Fabrika Y\u00f6ntemi Tasar\u0131m Desenini Ustala\u015fmak: Bir G\u00f6rev Y\u00f6netimi CLI Olu\u015fturmak<\/p>\n

Yaz\u0131l\u0131m d\u00fcnyas\u0131nda, uygulamalar\u0131n karma\u015f\u0131kl\u0131\u011f\u0131n\u0131 y\u00f6netmek ve tekrarlanan kodlar\u0131 ortadan kald\u0131rmak i\u00e7in \u00e7e\u015fitli tasar\u0131m desenleri kullan\u0131l\u0131yor. Bunlardan biri de Fabrika Y\u00f6ntemi tasar\u0131m deseni. Bu desen, nesne olu\u015fturma s\u00fcrecini soyutlayarak daha esnek ve s\u00fcrd\u00fcr\u00fclebilir kodlar yazmam\u0131z\u0131 sa\u011flar. Bu makalede, Fabrika Y\u00f6ntemi tasar\u0131m deseninin temel prensiplerini ele alaca\u011f\u0131z ve bu deseni kullanarak bir g\u00f6rev y\u00f6netimi komut sat\u0131r\u0131 aray\u00fcz\u00fc (CLI) nas\u0131l olu\u015fturulaca\u011f\u0131n\u0131 ad\u0131m ad\u0131m inceleyece\u011fiz.<\/p>\n

Fabrika Y\u00f6ntemi Tasar\u0131m Deseni Nedir?<\/h2>\n

Fabrika Y\u00f6ntemi tasar\u0131m deseni, bir s\u0131n\u0131f\u0131n alt s\u0131n\u0131flar\u0131na ait nesnelerin nas\u0131l olu\u015fturulaca\u011f\u0131n\u0131 tan\u0131mlamaya y\u00f6nelik bir \u00e7\u00f6z\u00fcm sunar. Bir Fabrika s\u0131n\u0131f\u0131, \u00e7e\u015fitli alt s\u0131n\u0131flar i\u00e7in ortak bir aray\u00fcz tan\u0131mlar ve bu aray\u00fcz \u00fczerinden istenen alt s\u0131n\u0131fa ait nesneler olu\u015fturulabilir. Bu sayede, kodumuzda nesne olu\u015fturma mant\u0131\u011f\u0131 merkezi bir noktada toplan\u0131r ve gerekti\u011finde farkl\u0131 alt s\u0131n\u0131flar kolayca de\u011fi\u015ftirilebilir.<\/p>\n

Fabrika Y\u00f6ntemi Tasar\u0131m Desenini Uygulama: G\u00f6rev Y\u00f6netimi CLI \u00d6rne\u011fi<\/h2>\n

\u015eimdi Fabrika Y\u00f6ntemi tasar\u0131m desenini kullanarak bir g\u00f6rev y\u00f6netimi CLI olu\u015ftural\u0131m. CLI, kullan\u0131c\u0131lar\u0131n g\u00f6revlerini eklemelerine, silmelerine, d\u00fczenlemelerine ve listelemelerine olanak sa\u011flayacakt\u0131r. <\/p>\n

1. G\u00f6rev Aray\u00fcz\u00fc Tan\u0131mlama<\/h3>\n

\u00d6ncelikle, t\u00fcm g\u00f6rev t\u00fcrleri i\u00e7in ortak bir aray\u00fcz tan\u0131mlar\u0131z. Bu aray\u00fcz, g\u00f6revlerin temel \u00f6zelliklerini (ba\u015fl\u0131k, a\u00e7\u0131klama, \u00f6ncelik) ve g\u00f6revler \u00fczerinde ger\u00e7ekle\u015ftirilecek i\u015flemleri (ekleme, silme, g\u00fcncelleme, listeleme) belirtir.<\/p>\n

“`java
\npublic interface Task {
\n String getTitle();
\n String getDescription();
\n int getPriority();
\n void addTask(String title, String description, int priority);
\n void deleteTask(String title);
\n void updateTask(String title, String description, int priority);
\n void listTasks();
\n}
\n“`<\/p>\n

2. G\u00f6rev Alt S\u0131n\u0131flar\u0131 Olu\u015fturma<\/h3>\n

Daha sonra, farkl\u0131 g\u00f6rev t\u00fcrlerini temsil eden alt s\u0131n\u0131flar olu\u015ftururuz. \u00d6rne\u011fin, “\u00d6nemli G\u00f6rev”, “Normal G\u00f6rev” ve “Ge\u00e7mi\u015f G\u00f6rev” alt s\u0131n\u0131flar\u0131 olu\u015fturabiliriz. Her alt s\u0131n\u0131f, “Task” aray\u00fcz\u00fcn\u00fc uygular ve kendi \u00f6zel i\u015flevselli\u011fini ekler.<\/p>\n

“`java
\npublic class ImportantTask implements Task {
\n \/\/ \u00d6zel i\u015flevsellik
\n}<\/p>\n

public class NormalTask implements Task {
\n \/\/ \u00d6zel i\u015flevsellik
\n}<\/p>\n

public class PastTask implements Task {
\n \/\/ \u00d6zel i\u015flevsellik
\n}
\n“`<\/p>\n

3. Fabrika S\u0131n\u0131f\u0131 Olu\u015fturma<\/h3>\n

Fabrika Y\u00f6ntemi tasar\u0131m desenini kullanarak, g\u00f6rev t\u00fcrlerini dinamik olarak olu\u015fturmak i\u00e7in bir “TaskFactory” s\u0131n\u0131f\u0131 olu\u015ftururuz. Bu s\u0131n\u0131f, g\u00f6rev t\u00fcr\u00fcn\u00fc bir parametre olarak al\u0131r ve ilgili alt s\u0131n\u0131f\u0131n bir \u00f6rne\u011fini d\u00f6nd\u00fcr\u00fcr.<\/p>\n

“`java
\npublic class TaskFactory {
\n public static Task createTask(String taskType) {
\n if (taskType.equals(“\u00d6nemli”)) {
\n return new ImportantTask();
\n } else if (taskType.equals(“Normal”)) {
\n return new NormalTask();
\n } else if (taskType.equals(“Ge\u00e7mi\u015f”)) {
\n return new PastTask();
\n } else {
\n return null;
\n }
\n }
\n}
\n“`<\/p>\n

4. CLI Uygulamas\u0131 Olu\u015fturma<\/h3>\n

Son olarak, kullan\u0131c\u0131 girdilerini i\u015fleyecek ve g\u00f6revleri y\u00f6netecek bir CLI uygulamas\u0131 olu\u015ftururuz. Kullan\u0131c\u0131lar, komut sat\u0131r\u0131 \u00fczerinden hangi g\u00f6rev t\u00fcr\u00fcn\u00fc olu\u015fturmak istediklerini belirtirler ve Fabrika s\u0131n\u0131f\u0131 bu iste\u011fe uygun g\u00f6rev nesnesini olu\u015fturur.<\/p>\n

“`java
\npublic class TaskManager {
\n public static void main(String[] args) {
\n Scanner scanner = new Scanner(System.in);
\n System.out.println(“G\u00f6rev T\u00fcr\u00fc Girin (\u00d6nemli, Normal, Ge\u00e7mi\u015f):”);
\n String taskType = scanner.nextLine();
\n Task task = TaskFactory.createTask(taskType);
\n \/\/ G\u00f6rev i\u015flemleri
\n }
\n}
\n“`<\/p>\n
