Answer / Ajay Kumar Mishra

In Salesforce Apex, casting is the process of converting one data type to another. This can be done using explicit and implicit casting.n
1. Explicit casting: This requires using the appropriate conversion function or operator. For example:nString myString = '123';nInteger myInt = Integer.valueOf(myString);n
2. Implicit casting: This happens automatically when you try to assign a value of one data type to another compatible data type.nFor example:nDouble myDouble = 123;nInteger myInt = (Integer)myDouble; // No need for explicit conversion here.
