The java.util Hashtable class is a package within the Java library that provides a way to store and retrieve key-value pairs in a hashtable. This implementation of the Map interface provides synchronized access to the hashtable, making it thread-safe.
In this example, a new Hashtable is created to store phone numbers for Alice, Bob, and Charlie. The put() method is used to add key-value pairs to the hashtable.
Example 2:
Hashtable countries = new Hashtable<>(); countries.put("USA", "United States"); countries.put("UK", "United Kingdom"); countries.put("DE", "Germany");
In this example, a new Hashtable is created to store country codes and their corresponding names. The put() method is used to add key-value pairs to the hashtable.
The Hashtable class is part of the java.util package library in Java.
