my Question is will we have any drawbacks using this design?and this is also typesafe enum design pattern Right?

public final class Language { private Language() { } interface ConstantValues { Language ENGLISH = new Language("English"); Language FRENCH = new Language("French"); Language SPANISH = new Language("Spanish"); } }

still I have not cleared doubt regarding preceding design pattern.I don't know why I worry so much about these things.
Has anybody else here read the above code and if so, what are your thoughts? Jesper... ?Rob...?

Hi ulrika,

java.io.ObjectStreamConstants is constant interface in the Java 1.6, why sun has not used java.lang.Enum for defining constants?

Hi Friends,

public final class Language { private String name; private Language(String name) { this.name = name; } public static final Language ENGLISH = new Language("English"); public static final Language FRENCH = new Language("French"); public static final Language SPANISH = new Language("Spanish"); public String toString() { return name; } }
The preceding code is 'type safe enum' design pattern,then Why should we go for java.lang.Enum?
