        Class<ArrayList> classObj = ArrayList.class;

        /*
         * Returns:an array of interfaces implemented by this class.
         * 
         * A class can implement many interfaces. Therefore an array of Class is

         * Reflection.
         */

        Class[] classArray = classObj.getInterfaces();

        for (Class class1 : classArray)
        {
            System.out.println(class1.getName());
        }

    }

}

Output

java.util.List
java.util.RandomAccess
java.lang.Cloneable
java.io.Serializable
