     String str = "This is from";

     Class cls = str.getClass();
     boolean arr = cls.isArray();
     Object array = Array.newInstance(int.class, 3);
     Class type = array.getClass();
     if (type.isArray()) {
       Class elementType = type.getComponentType();
       System.out.println("Array of: " + elementType);
       System.out.println("Array size: " + Array.getLength(array));

The code above generates the following result.
