How to make a Java Generic method static?

The following is a snippet on how to make a java generic class to append a single item to an array. How can I make appendToArray a static method. Adding static to the method signature results in compile errors.

public class ArrayUtils<E> {

        public E[] appendToArray(E[] array, E item) {
            E[] result = (E[])new Object[array.length+1];
            result[array.length] = item;
            return result;
        }
}
