java LinkedList三种遍历方法

三种遍历方法为：迭代器遍历，增强for循环，普通for循环，代码如下：

import java.util.Iterator;
import java.util.LinkedList;

public class LinklistDemo {
	public static void main(String[] args) {
		LinkedList<String> listedList = new LinkedList<String>();
		listedList.add("小明");
		listedList.add("小红");
		listedList.add("小蓝");
		listedList.add("小军");
		//迭代器
		Iterator it = listedList.iterator();
		while(it.hasNext()){
			System.out.println(it.next()+" ");
		}
		
		//增强for循环
		for(String s:listedList) {
			System.out.println(s+" ");
		}
		
		//普通for循环
		for (int i = 0; i < listedList.size(); i++) {
			System.out.println(listedList.get(i)+" ");
		}
	}
}
