    text
    copied!<p>I've just got back to MIDP development after some 4 years of .NET 2 and Java 5 and 6. During that time I got to like using enums quite a lot.</p> <p>Enum is a language feature that allows a developer to have more confidence in some parts of his code, specially for being able to avoid or detect errors earlier (during compilation). Some other advantages can be found here: <strong>http:// java.sun.com/j2se/1.5.0/docs/guide/language/enums.html</strong></p> <p>I found it strange that I couldn't find them in MIDP 2.0. I've got this error message:</p> <blockquote> <p>"Type 'enum' should not be used as an identifier, since it is a reserved keyword from source level 1.5"</p> </blockquote> <p>I had some experience in Java 1.4 a while back, but I didn't remember this. There sure are some features of newer versions of your high-level languages that you get to take for granted...</p> <p>Anyway, here is a good recommendation for what to do without them (if you're developing MIDP or dealing with code prior to Java 5): <strong>http:// www.javacamp.org/designPattern/enum.html</strong></p> <p>Summing it up (for more details and a good explanation, follow the previous link. Many thanks to the original author):</p> <pre><code>//The typesafe enum pattern public class Suit { private final String name; public static final Suit CLUBS =new Suit("clubs"); public static final Suit DIAMONDS =new Suit("diamonds"); public static final Suit HEARTS =new Suit("hearts"); public static final Suit SPADES =new Suit("spades"); private Suit(String name){ this.name =name; } public String toString(){ return name; } } </code></pre> <p>Do you have any other different approaches to this issue?</p>
