Accessing array classes

[ohoehle]

Hi!

There is a given object of type java.lang.Class and I want to get the
array class corresponding to my class, aka the Class object with a
componentType identical to the given Class object.

I did it this way...

public static Class getArrayClass(Class componentType) {
return Array.newInstance(componentType, 0).getClass();
}


but creating an array just to get its class is &§&%/()/%$/&%$!!! in my
eyes...

Do you know a better solution?

Regards
Oliver

This is something of a FAQ (not to mention something of a stupid omission from
java.lang.Class). One discussion of the issue which I remember ('cos I took
part in it -- and because it went memorably and entertainingly wrong after a
while ;-) is here:
