How do I reverse a string using CharacterIterator in Java?

In this example we use the CharacterIterator implementation class StringCharacterIterator to reverse a string. It's done by reading a string from the last index up to the beginning of the string.

import java.text.CharacterIterator;
import java.text.StringCharacterIterator;

public class ReverseStringCharacterExample {
    private static final String text = "Jackdaws love my big sphinx of quartz";

    public static void main(String[] args) {
        CharacterIterator it = new StringCharacterIterator(text);

        //
        // Iterates a string from the last index to the beginning.
        //
        for (char ch = it.last(); ch != CharacterIterator.DONE; ch = it.previous()) {
            System.out.print(ch);
        }
    }
}
