可以通過2種方法遍歷HashMap
Map map = new HashMap();
for (Iterator iter = map.entrySet().iterator(); iter.hasNext();) {
Map.Entry entry = (Map.Entry) iter.next();
Object key = entry.getKey();
Object val = entry.getValue();
}
或者:
Map map = new HashMap();
for (Iterator iter = map.keySet().iterator(); iter.hasNext();) {
Object key = iter.next();
Object val = map.get(key);
}
