I've lots of different structs containing enum members that I have to transmit via TCP/IP. While the communication endpoints are on different operating systems (Windows XP and Linux) meaning different compilers (gcc 4.x.x and MSVC 2008) both program parts share the same header files with type declarations.
For performance reasons, the s...
i have read the following on Java enum but still confused.
i would like the following:
public enum Checker {
EMPTY ("Empty"),
RED ("Red"),
YELLOW ("Yellow");
}
to return the related String. from what i have read, this should be possible. just would like you to shed some light on it on how to implement it.
thank you.

I'm trying to design a Web Part that has a drop-down list for the user to choose from. Eventually, these values will be automatically generated based on some kind of outside data source, so they're going to have somewhat arbitrary numeric values associated with them. This is the code I have now:
public enum filterChoice

When I serialize an object, I can use the serialVersionUID mechanism at the class level to ensure the compatibility of the two types.
However, what happens when I serialize fields of enum values? Is there a way to ensure that the enum type has not been manipulated between serialization and deserialization?
Suppose that I have an enum ...

Is it possible to design your own Java Type, similar to an extensible enum?
For instance, I have user roles that a certain module uses and then a sub-package provides additional roles.
What would be involved on the JDK side of things?

Let's say I have a function that takes a string. That string contains the fully name of an enum type (e.g. "MyCompany.Area.AotherNamespace.MyEnum").
How could I create an array of strings (or List<string>) whose elements are the values of MyCompany.Area.AotherNamespace.MyEnum?
Is that even possible?

I am trying to read the value of an enum in an annotation using an annotation processor and annotation mirror, but I am getting back null. I think this has to do with the AnnotationValue wrapping an Enum as a VariableElement. The doc for VariableElement#getConstantValue() says "Returns the value of this variable if this is a final field ...

I have the following enum
public enum TESTENUM
{
Value1 = 1,
Value2 = 2
}
I then want to use this to compare to an integer variable that I have, like this:
if ( myValue == TESTENUM.Value1 )
{
}
But in order to do this test I have to cast the enum as follows (or presumably declare the integer as type enum):
if ( myValue == ...
I have several flag-like enumerations, in C++. For example:

};
