java遍历Map

如遍历 Map<A,B> map

 

Set<Entry<Integer,String>> vs = urlMapping.entrySet(); Entry<Integer,String> entry = null; for(Iterator<Entry<Integer,String>> iter=vs.iterator();iter.hasNext();){ entry=iter.next(); int episode = entry.getKey(); String url = entry.getValue();

 

 

for(Iterator<Entry<Integer,Map<Integer,String>>> iter=urls.entrySet().iterator();iter.hasNext();){ Entry<Integer,Map<Integer,String>> entry=iter.next(); }
