Java使用ListIterator遍历列表

import java.util.*;


public class ListTrim {/*N o  w  J a v a . c o m - 时  代  Java 提供*/

    static void listTrim(List<String> strings) {

        for (ListIterator<String> lit = strings.listIterator(); lit

                .hasNext();) {

            lit.set(lit.next().trim());

        }

    }


    public static void main(String[] args) {

        List<String> l = Arrays.asList(" red ", " white ", " blue ");

        listTrim(l);/** N o w J a v a . c o m - 时代Java 提供 **/

        for (String s : l) {

            System.out.format("\"%s\"%n", s);

        }

    }

}
