We have also created functions to implement all the basic four functionalities of the dictionary that are create, delete, update, etc.Īs we can see in the output of the above code, we have 4 elements as input to our dictionary object created and then update one value in the dictionary and then we deleted one value in the dictionary and in the last we have printed the final dictionary object.Ī sample java code to perform all the basic operations like create, delete and update. In this code, we have created a dictionary object named players having key as integer and value as Print('The dictionary after deleting the values is:') Print('The dictionary after updating the values is:') # function to print all the elements of the dictionary object named players Print('Enter the key that you want to delete or remove from the dictionary object') # function to delete the elements of the dictionary object named players Print('Enter the new value that you want to assign to the key entered') Print('Enter the key whose value you want to update') # function to udpate the values of the elements of the

Print('Enter the player name to be entered') Print('Enter the jersey number to be entered') # function to add or insert data into the dictionary object named players # creating a dictionary object named players having key as jersey number and value as the name of the player Now, let us see the usage of the dictionary data structure in different programming languages.Ī sample python code to perform all the basic four operations like create, update, delete and update.

Find or Lookup: In the Find or Lookup operation, the value associated with a key is searched by passing the key as a search argument.

Delete or remove: In the Delete or remove operation, the already present element is unmapped from the Dictionary or associative array object.

In other words, a new value is mapped to an already existing key.

Replace or reassign: In the Replace or reassign operation, the already existing value that is associated with a key is changed or modified.

Add or Insert: In the Add or Insert operation, a new pair of keys and values is added in the Dictionary or associative array object.

The various operations that are performed on a Dictionary or associative array are: We can say that each value in the dictionary is mapped to a particular key present in the dictionary or vice-versa. In Dictionary or associative array, the relation or association between the key and the value is known as the mapping. A direct form of hardware-level support for the Dictionary or associative array is Content-addressable memory.

Many popular languages add Dictionary or associative array as a primitive data type in their languages while other languages which don't consider Dictionary or associative array as a primitive data type have included Dictionary or associative array in their software libraries.

Other names for the Dictionary data structure are associative array, map, symbol table but broadly it is referred to as Dictionary.Ī dictionary or associative array is a general-purpose data structure that is used for the storage of a group of objects. In other words, we can also say that Dictionary data structure is used to store the data in key-value pairs. Each element presents in a dictionary data structure compulsorily have a key and some value is associated with that particular key. Dictionary is one of the important Data Structures that is usually used to store data in the key-value format.
