Concept explainers
Look at the following interface:
public interface Computable
{
double compute(double x);
}
Write a statement that uses a lambda expression to create an object that implements the Computable interface. The object’s name should he half. The half object’s compute method should return the value of the x parameter divided by 2.

- It is required to develop an application in Java to perform some operations to store information about items in a store. The application will have the following classes: (A) An abstract class called item having foliowing data fieids (private): itemName (String), itemNumlingi, makeStringl, pricejdouble) and following methods: () Default constructor - without any parameters, (i) Constructor having 4 parameters to initialize ali data fields, (i) Set and get methods for all data fields separately. (iM) tostring method to retum string representation of all data members, (M Abstract method totalPrice to return total price. (8) Write a concrete class (with implementation of all methods) called Storeltem, which inherits the properties of class item. This new class has the following additional members Data fields (privatel quantity (int), disceuntRateldouble). Note that discountRate is % of the sale price. Methods.

T/F: The scope of instance and static variables is the entire class. They can be declared anywhere inside a class. T/F: To declare static variables, constants, and methods, use the static modifier.arrow_forward

Furthermore, each flight has a unique flight ID and the information whether the flight is direct or not.Create a C++ class to model a flight. (Note: Make separate classes for Date and Time and use composition).add two integer data members to the Flight class, one to store the total number of seats in the flight and the other to store the number of seats that have been reserved. Provide all standard functions in each of the Date, Time and Flight classes (Constructors, set/get methods and display methods etc.).Add a member function delayFlight(int) in the Flight class to delay the flight by the number of minutes pass as input to this function. (For simplicity, assume that delaying a flight will not change the Date). Add a member function reserveSeat(int) which reserves the number of seats passed as…arrow_forward
