B$.$ Create a Demo class to accomplish the following requirements:

Create four objects of type Product and add them to a list named productList of type ArraySortedList. The objects should be sorted based on the productPrice in ascending order.

Define a static method named retrieveAvailableProducts, which takes three parameters: productList of type ArraySortedList, minPrice of type double, and maxPrice of type double. This method should retrieve a sub$-$list from productList containing all products within the specified price range where isAvailable is true.
