From wikipedia (so it must be true):

Java

The J2SE version 5.0 of the Java programming language added enumerated types whose declaration syntax is similar to that of C's:
Code:

 enum Cardsuit { Clubs, Diamonds, Spades, Hearts }
 ...
 Cardsuit trump ;
 

The Java type system, however, treats enumerations as a type separate from integers, and intermixing of enum and integer values is not allowed (except that you can retrieve the integer out of an enum value using the .ordinal() method). In fact, an enum type in Java is actually a special compiler-generated class rather than an arithmetic type, and enum values behave as global pre-generated instances of that class. Enum types can have instance methods and a constructor (the arguments of which can be specified separately for each enum value). All enum types implicitly extend the Enum abstract class. An enum type cannot be instantiated directly.


The version of Java is of note here. For installation specific purposes you may be fine - don't depend on all of your users having Java 5.0 or later. And you may want to look in the Processing FAQ regarding Java versions.

I guess more java-1.4-conform methods like these will work:

String[] DAYS;
void setup() {
DAYS=new String[7];
DAYS[0]= "SUNDAY";
...(dont forget to fill the arr)
DAYS[6]="SATURDAY";
}
public String[] getDays() {
return DAYS;
}
public String getDay(int indx) {
return DAYS[indx];
}

If you want to use a container with mixed objs (like String, Diamond, Blood ...) use e.g. ArrayList.
