WebThis class implements a hash table, which maps keys to values. Any non- null object can be used as a key or as a value. To successfully store and retrieve objects from a hashtable, the objects used as keys must implement the hashCode method and the equals method. An instance of Hashtable has two parameters that affect its performance: initial ... WebMethods are provided to enumerate through the elements of a vector, the keys of a hashtable, and the values in a hashtable. Enumerations are also used to specify the input streams to a SequenceInputStream. NOTE: The functionality of this interface is duplicated by the Iterator interface. In addition, Iterator adds an optional remove operation ... WebGetEnumerator in PowerShell iterates through the HashTable and displays the keys and values of the HashTable. To read all items of HashTable, use GetEnumerator and pipe the HashTable output objects to ForEach-Object. ForEach-Object loop through the objects and prints the keys and values of the HashTable. thema probandum termine
