我是靠谱客的博主苹果招牌，最近开发中收集的这篇文章主要介绍List&Map用循环获取集合中的值，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

map循环

Java代码

Mapmap=newHashMap();
map.put("1","qiao1");
map.put("2","qiao2");
map.put("3","qiao3");
map.put("4","qiao4");
map.put("5","qiao5");
Iteratoriterator2=map.entrySet().iterator();
//JDK1.4
while(iterator2.hasNext()){
Map.Entryentry=(Map.Entry)iterator2.next();
System.out.println("key:="+entry.getKey());
System.out.println("key:="+entry.getValue());
System.out.println("all:="+iterator2.next());
}
//JDK1.5
for(Objecto:map.keySet()){
System.out.println("key:="+o);
System.out.println("value:+"+map.get(o));
}

Map map= new HashMap();
		map.put("1", "qiao1");
		map.put("2", "qiao2");
		map.put("3", "qiao3");
		map.put("4", "qiao4");
		map.put("5", "qiao5");
		Iterator iterator2=map.entrySet().iterator();
		//JDK 1.4
		while(iterator2.hasNext()){
			Map.Entry   entry= (Map.Entry)iterator2.next();   
			System.out.println("key:="+entry.getKey());
			System.out.println("key:="+entry.getValue());
			System.out.println("all:="+iterator2.next());
		}
		//JDK 1.5 
		for(Object o: map.keySet()){
			System.out.println("key:="+o);
			System.out.println("value:+"+map.get(o));
		}
