如何使用foreach使类可迭代？

import java.util.Iterator;

public class MyClass implements Iterable<String> {
    private String[] elements;

    public MyClass(String[] elements) {
        this.elements = elements;
    }

    @Override
    public Iterator<String> iterator() {
        return new MyIterator();
    }

    private class MyIterator implements Iterator<String> {
        private int index = 0;

        @Override
        public boolean hasNext() {
            return index < elements.length;
        }

        @Override
        public String next() {
            return elements[index++];
        }

        @Override
        public void remove() {
            throw new UnsupportedOperationException();
        }
    }

    public static void main(String[] args) {
        String[] elements = {"A", "B", "C"};
        MyClass myClass = new MyClass(elements);

        for (String element : myClass) {
            System.out.println(element);
        }
    }
}
