- Problem No. 2 Write a Java class called ContainsInRange. This class defines a method called contains(), which takes as parameters an integer array a, an integer x, an int called start, as well as an int called end, and returns a boolean which is true if and only if x occurs in a at a position which is greater than or equal to start, and less than end. You must validate that start is less than or equal to end, and that both start and end are greater than or equal to 0, and less than or equal to a.length. Repeat the operation often. (please put also the code that the user can enter a value. Thank you)Create a class with name savingaccont.In this class you have to write the static method having name CalculteFutureValue which takes three parameters of type double along with return type double.This function should implement the formula given below.The formula, which is known as the future value formula, is:F = P * (1 + i)tThe terms in the formula are as follows: F is the future value of the account after the specified time period. P is the present value of the account. i is the monthly interest rate . t is the number of months . Write Driver class which contains main function that prompts the user to enter the account’s present value, monthly interest rate, and the number of months that the money will be left in the account. The program should pass these values to a function named CalculteFutureValue that returns the future value of the account, after the specified number of months. The program should display the account’s future value.JAVA PROGRAM Chapter 7. PC #1.

- in C# i need to Create a program named PaintingDemo that instantiates an array of eight Room objects and demonstrates the Room methods. The Room constructor requires parameters for length, width, and height fields (all of type int); use a variety of values when constructing the objects. The Room class also contains the following fields: Area - The wall area of the Room (as an int) Gallons - The number of gallons of paint needed to paint the room (as an int) Both of these values are computed by calling private methods. Include read-only properties to get a Room’s values. A room is assumed to have four walls, and you do not need to allow for windows and doors, and you do not need to allow for painting the ceiling. A room requires one gallon of paint for every 350 square feet (plus an extra gallon for any square feet greater than 350). In other words, a 12 x 3 x 10 room with 9-foot ceilings has 396 square feet of wall space, and so requires two gallons of paint. the errors are Room…In C# i need to Create a program named PaintingDemo that instantiates an array of eight Room objects and demonstrates the Room methods.
