以下实例演示了如何使用 Collection 类的 iterator() 方法来遍历集合：
Main.java 文件
import java.util.*;
public class Main {
public static void main(String[] args) {
HashMap< String, String> hMap =
new HashMap< String, String>();
hMap.put("1", "1st");
hMap.put("2", "2nd");
hMap.put("3", "3rd");
Collection cl = hMap.values();
Iterator itr = cl.iterator();
while (itr.hasNext()) {
System.out.println(itr.next());
}
}
}
以上代码运行输出结果为：
1st 2nd 3rd
