Cоmplete the cоde tо implement а generic clаss . The clаss should only accept objects of types that extend a given class. You need to: Create a Generic Calculator class that can perform mathematical operations like addition and multiplication on different types of numeric values. The class should have the following features: The class should accept numbers of type T where T can be any type that extends Number (such as Integer, Double, Float).Implement two methods:add(): Adds two numbers of type T and returns the sum. Ensure that the method works for any type of Number.multiply(): Multiplies two numbers of type T and returns the product.Main Class: In the main method, create instances of GenericCalculator for different numeric types, such as Integer, Double, and Float.Use the calculator to add and multiply different values. // Create a generic class that works for any subclass of Numberclass GenericCalculator { // Method to add two numbers of type T public double add( ___ a, __ b) { } // Method to multiply two numbers of type T public double multiply(__ a, __ b) { }} class Main { public static void main(String[] args) { // Create a GenericCalculator for Integer type and call its methods // Create a GenericCalculator for Double type and call its methods // Create a GenericCalculator for Float type and call its methods }}
