Hashtable values遍历例子，hashtablevalues,package cn.o

package cn.outofmemory.snippets.core;import java.util.Hashtable;import java.util.Enumeration;public class HashtableValuesIterator {  public static void main(String[] args) {    // Create a Hashtable and populate it with elements    Hashtable hashtable = new Hashtable();    hashtable.put("key_1","value_1");    hashtable.put("key_2","value_2");    hashtable.put("key_3","value_3");    // Enumeration elements() operation returns an Enumeration of values contained in Hashtable    Enumeration valuesEnumeration = hashtable.elements();    // Iterate through Hashtable values Enumeration    System.out.println("Hashtable values : ");    while(valuesEnumeration.hasMoreElements())      System.out.println(valuesEnumeration.nextElement());  }}

输出：

Hashtable values : value_3value_2value_1
