Question

I use the following trick to get the array type of a specific class:

@SuppressWarnings("unchecked")
public static <T> Class<T[]> getArrayType(Class<T> componentType) {
    String arrayClassName = "[L" + componentType.getName() + ";";
    try {
        return (Class<T[]>) Class.forName(arrayClassName);
    } catch (ClassNotFoundException e) {
        throw new UnexpectedException("Can't get the array type for " + componentType, e);
    }
}

But, is there any more elegant way to get this?

Answer 1

Perhaps using Array.newInstance(), which returns an array of a given type.

Doing something like:

return Array.newInstance(someClass, 0).getClass()

Might get you what you want.

Hope that helps.
