Examples of java.util.Hashtable$HashEnumerator

java.util.Hashtable
Hashtable associates keys with values. Keys and values cannot be null. The size of the Hashtable is the number of key/value pairs it contains. The capacity is the number of key/value pairs the Hashtable can hold. The load factor is a float value which determines how full the Hashtable gets before expanding the capacity. If the load factor of the Hashtable is exceeded, the capacity is doubled. @see Enumeration @see java.io.Serializable @see java.lang.Object#equals @see java.lang.Object#hashCode
