Answer / Sourabh Sharma
The `apply` method in Scala is used to call a function with its arguments passed as parameters, rather than invoking it like a regular method. Conversely, the `unapply` method takes an object and attempts to deconstruct it into its constituent parts according to some pattern. The primary difference between these two methods lies in their purpose: `apply` is used for constructing values from inputs, while `unapply` is used for destructuring values according to a defined pattern.
