HashTable 순회 방법
Hashtable<String, String> hashtable = new Hashtable<String, String>(); hashtable.put("1", "a"); hashtable.put("2", "b"); hashtable.put("3", "c"); hashtable.put("4", "d"); Enumeration<String> enumKey = hashtable.keys(); while(enumKey.hasMoreElements()){ String key = enumKey.nextElement(); String value = hashtable.get(key); System.out.println(value); } | cs |
HashMap 순회방법
