// create a new Hashtable HashtableIn this example, we create a new Hashtable to store some numbers. We add three key-value pairs to the Hashtable, and then we remove the entry with the key "two". Finally, we print the updated Hashtable to verify that the entry has been removed. The java.util package is a standard library package in Java, so we do not need to import it explicitly.numbers = new Hashtable<>(); // add some key-value pairs numbers.put("one", 1); numbers.put("two", 2); numbers.put("three", 3); // remove an entry numbers.remove("two"); // print the updated Hashtable System.out.println(numbers);
