Getting the class of the components of an array

Question

If I have

public <T> doSomething(T[] array)
{
}

how can I get T.class from array?

If I do array.getClass() that gets me T[].class instead.

If you want to do this for multi-dimensional arrays the following recursive code will work

public static Class<?> getArrayType(Object array) {
    Object element = Array.get(array, 0);
    if (element.getClass().isArray()) {
        return getArrayType(element);
    } else {
        return array.getClass().getComponentType();
    }
}
