find class of array (String[].class --> String.class) [duplicate]

I've got an array of any class and I need to get that class at runntime.

I'm thinking of something like that:

String[] stringArray = new String[10];
Class<?> clazz = stringArray.getClass();
if (String.class.isAssignableFrom(clazz)) {
    System.out.println("Won't happen");
}

The class of the array is not known at compile time.

I've found something simular but the other way here (String.class --> String[].class)
