测试发帖--记录一下遍历HashMap的方法

Iterator it = ftd.numOfModule.keySet().iterator();
while (it.hasNext()) {
Object obj = it.next();
System.out.println(obj + ": " + ftd.numOfModule.get(obj)); }
int mapsize = ftd.numOfModule.size();
Iterator keyValuePairs1 = ftd.numOfModule.entrySet().iterator();
for (int i = 0; i < mapsize; i++)
{
Map.Entry entry = (Map.Entry) keyValuePairs1.next();
Object key = entry.getKey();
Object value = entry.getValue();
System.out.println("update "+key + ": " + value);
}
