【笔记】遍历Map的方法

mapA为HashMap<String, String>

Set entrySet = mapA.entrySet();

int i=0; for(Iterator iter = entrySet.iterator(); iter.next);{   i++;   Map.Entry entry = iter.next();   System.out.println("the "+i+"th key is"entry.getKey());   System.out.println("the "+i+"th value is"entry.getValue());}
