- Implement all the classes using Java programming language from the given UML Class diagram. Note: This problem requires you to submit just two classes: Customer.java, Account.java. Do NOT include "public static void main()" method inside all of these classes. Graders will be testing your classes, using the unit-testing framework JUnit 4. Customer - ID:int -name:String -gender:char 'm' or 'f' +Customer(ID:int,name:String, discount:int) +getID():int +getName ():String +getGender ():char +toString():String "name (ID)" The Customer class models, customer design as shown in the class diagram.

It has the following signature: void SortByPrice(std::vector<Snack>& list_ref, bool asc). This function should sort the vector list_ref based on the price_ of the Snacks. The sorting should be done in the following order: Ascending if asc is true Descending if asc is false. In both cases if variables have the same value for price_, the sorting should be done based on the name_ in ascending order.#include <string>#include <iostream>#include <vector>class Snack{public:Snack(std::string, float, bool);int set_price(float);void set_expired(bool);void set_name(std::string);std::string name() const{return name_;}float price() const{return price_;}bool expired() const{return expr_;}int how_many_for_ten();private:std::string name_;float price_;bool expr_;};void SortByPrice(std::vector<Snack>&,bool); Task: Define the public function int Snack::set_price(float price) : If the value passed by price is smaller than 0 the function should return -2. If the value of price is greater or equal to 0, proceed as follows: If the value passed by price is smaller than the current value of price_, the function should assign price to price_ and return -1. If the value passed by price is larger than the current value of price_, the function should assign price to price_ and return 1. If price is equal to price_, the function should assign price to price_ and return…
