How do I reverse a string using CharacterIterator?
Category: java.text, viewed: 7K time(s).
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.
package org.kodejava.example.text;
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);
}
}
}
