Question

求教arraylist里面放map，怎么循环遍历得到map里面的数据，如：List<Map<String, String>> list = new Ar

如：List<Map<String, String>> list = new Ar
发错了，是List<Map<String, String>> list = new ArrayList<Map<String,String>>();

Answer 1

for(Map map : list){
Iterator i =map.keySet().iterator();
while( i.hasNext() ){
System.out.println( i.next().getValue() );
}
}

Answer 2

for (Map map : list) {
for (Iterator iterator = map.keySet().iterator(); iterator.hasNext();) {
String key = (String)iterator.next();
System.out.println(key+"="+map.get(key));
}
}

Answer 3

Iterator i = list.iterator();
while(i.hasNext()) {
i.next.getValue();
}

Answer 4

这种问题八度一下就可以了。
java如何遍历List？
