Map的常见遍历方式

[java] view plain copy

1. Map<String,String>map=newHashMap();
3. for(Map.Entryentry:map.entrySet()){
5. Objectkey=entry.getKey();
7. }

[java] view plain copy

1. Maphashmap=newHashMap();
3. Setset=hashmap.entrySet();
5. Iteratoriterator=set.iterator();
7. while(iterator.hasNext(){
9. Map.Entrymapentry=(Map.Entry)iterator.next();
11. System.out.println(mapentry.getkey()+"/"+mapentry.getValue());
13. }

[java] view plain copy

1. Setkeys=map.keySet();
3. if(keys!=null){
5. Iteratoriterator=keys.iterator();
7. while(iterator.hasNext()){
9. Objectkey=iterator.next();
11. Objectvalue=map.get(key);
13. }
15. }
