Description
Sep 25, 2018 In this 5th article in our Salesforce learning journey we will have some more insights on Salesforce object relationships. We will also see how Formula field in Salesforce is defined. Relationships: Relationships are used to connect Salesforces objects with each other. We can define three relationships on salesforce objects based on their scope about data.
Program to get value from HashMap when the key is provided.
Example
Output:
Note: In the above program the key 5 is not mapped to any value so the get() method returned null, However you must not use this method for checking existence of a Key in HashMap because a return value of null does not necessarily indicate that the map contains no mapping for the key; it’s also possible that the map explicitly maps the key to null. Ms office 2013 activator and product key generator (full activation). You must use the containsKey() method for checking the existence of a Key in HashMap.
