Retrieving values in a hash table

You can retrieve the value of a particular key using the get() method. If you pass the key of a particular element as a parameter of this method, it returns the value of the specified key (as an object). If the hash table doesn’t contain any element under the specified key it returns null.

You can retrieve the values in a hash table using this method.

Example

import java.util.Hashtable;
public class RetrievingElements {
   public static void main(String args[]) {
      Hashtable hashTable = new Hashtable();
      hashTable.put("Ram", 94.6);
      hashTable.put("Rahim", 92);
      hashTable.put("Robert", 85);
      hashTable.put("Roja", 93);
      hashTable.put("Raja", 75);      
      
      Object ob = hashTable.get("Ram");
      System.out.println("Value of the specified key :"+ ob);            
   }
}

Output

Value of the specified key :94.6
