A. Yes
B. No

Answer 1

A.Yes, it is possible to read a parameter value from the URL in Apex using ApexPages.currentPage().getParameters() method, which retrieves a map of all URL parameters allowing for access to specific values with a key.

Step-by-step explanation:

The question asks whether it is possible to read a parameter value from the URL in Apex. The answer is Yes, Apex, which is a programming language used for Salesforce development, provides the capability to read values from URL parameters.

This can be particularly useful when developing custom pages or applications within Salesforce that rely on URL parameters for context or actions. In Apex, the ApexPages.currentPage().getParameters() method can be used to retrieve a map of all the URL parameters.

Then, one can access the desired parameter value using the appropriate key. For example, if you wanted to read a parameter named 'id' from the URL, you would use ApexPages.currentPage().getParameters().get('id'). This would return the value associated with the 'id' parameter from the URL, which might be an identifier for a particular record in Salesforce.
