In the Java programming +// language, you define an enum type by using the enum keyword. For example, +// you would specify a days-of-the-week enum type as: +public enum Day { + SUNDAY, MONDAY, TUESDAY, WEDNESDAY, + THURSDAY, FRIDAY, SATURDAY +} + +// We can use our enum Day like that: +public class EnumTest { + // Variable Enum + Day day; + + public EnumTest(Day day) { + this.day = day; + } + + public void tellItLikeItIs() { + switch (day) { + case MONDAY: + System.out.println("Mondays are bad."); + break; + case FRIDAY: + System.out.println("Fridays are better."); + break; + case SATURDAY: + case SUNDAY: + System.out.println("Weekends are best."); + break; + default: + System.out.println("Midweek days are so-so."); + break; + } + } + + public static void main(String[] args) { + EnumTest firstDay = new EnumTest(Day.MONDAY); + firstDay.tellItLikeItIs(); // => Mondays are bad. + EnumTest thirdDay = new EnumTest(Day.WEDNESDAY); + thirdDay.tellItLikeItIs(); // => Midweek days are so-so. + } +} + +// Enum types are much more powerful than we show above. +// The enum body can include methods and other fields. +// You can see more at https://docs.oracle.com/javase/tutorial/java/javaOO/enum.html + +``` + +## مطالب بیشتر + +لینکهای زیر را می توانید برای پیگیرهای بیشتر استفاده کنید. +البته همیشه گوگل را در کنار دستتان داشته باشید! + +**سایت های راهنمای اصلی**: + +* [Java Tutorial Trail from Sun / Oracle](https://docs.oracle.com/javase/tutorial/index.html) + +* [Java Access level modifiers](https://docs.oracle.com/javase/tutorial/java/javaOO/accesscontrol.html) + +* [Object-Oriented Programming Concepts](https://docs.oracle.com/javase/tutorial/java/concepts/index.html): + * [Inheritance](https://docs.oracle.com/javase/tutorial/java/IandI/subclasses.html) + * [Polymorphism](https://docs.oracle.com/javase/tutorial/java/IandI/polymorphism.html) + * [Abstraction](https://docs.oracle.com/javase/tutorial/java/IandI/abstract.html) + +* [Exceptions](https://docs.oracle.com/javase/tutorial/essential/exceptions/index.html) + +* [Interfaces](https://docs.oracle.com/javase/tutorial/java/IandI/createinterface.html) + +* [Generics](https://docs.oracle.com/javase/tutorial/java/generics/index.html) + +* [Java Code Conventions](https://www.oracle.com/technetwork/java/codeconvtoc-136057.html) + +* New features in Java 8: + * [Lambda expressions (functional programming)](https://docs.oracle.com/javase/tutorial/java/javaOO/lambdaexpressions.html) + * [Date and time API (java.time package)](http://www.oracle.com/technetwork/articles/java/jf14-date-time-2125367.html) + +**راهنما و سایت های آموزشی** + +* [Learneroo.com -
