实例 Java 循环遍历一个迭代器

import java.util.ArrayList;

import java.util.Iterator;

​

public class Main {

  public static void main(String[] args) {

    // Make a collection

    ArrayList<String> cars = new ArrayList<String>();

    cars.add("Volvo");

    cars.add("BMW");

    cars.add("Ford");

    cars.add("Mazda");

    // Get the iterator

    Iterator<String> it = cars.iterator();

    // Loop through a collection

    while(it.hasNext()) {

      System.out.println(it.next());

    }

  }

}
