Java如何使用CharacterIterator反转字符串？
在此示例中，我们使用java.text.CharacterIterator实现类java.text.StringCharacterIterator来反转字符串。通过从最后一个索引到字符串的开头读取字符串来完成此操作。
package org.nhooo.example.text;
import java.text.CharacterIterator;
import java.text.StringCharacterIterator;
public class StringCharacterIteratorReverseExample {
private static final String text = "Jackdaws love my big sphinx of quartz";
public static void main(String[] args) {
CharacterIterator it = new StringCharacterIterator(text);
System.out.println("Before = " + text);
System.out.print("After = ");
//从最后一个索引到开始迭代一个字符串。
for (char ch = it.last(); ch != CharacterIterator.DONE; ch = it.previous()) {
System.out.print(ch);
}
}
}上面的代码片段的结果：
Before = Jackdaws love my big sphinx of quartz After = ztrauq fo xnihps gib ym evol swadkcaJ
