Write a program in a class FlowerCounter that computes the cost of flowers sold at a flower stand. Five kinds of flowers—petunia, pansy, rose, violet, and carnation—are stocked and cost, respectively, 50¢ 75¢, $1.50, 50¢, and 80¢ per flower. Create an array of strings that holds the names of these flowers. Create another array that holds the cost of each corresponding flower. Your program should read the name of a flower and the quantity desired by a customer. Locate the flower in the name array and use that index to find the cost per stem in the cost array. Compute and print the total cost of the sale.

The program should have methods that return the following: • the total rainfall for the year • the average monthly rainfall • the month with the most rain • the month with the least rain • Test the RainFall class by writing a tester class, RainFallDemo , to produce the outputs similar to the sample execution below. For the rainfall values, you must get them from the user’s input as double values in the tester class. For the class RainFall you must write standard Java Documentation for the whole class on the top, and for every method. Input Validation: Do not accept negative numbers for monthly rainfall figures. If a value is negative, ask the user to re-enter the input.arrow_forward
- Write a program in Java that reads integers, one per line, and displays their sum. Also, display all the numbers read, each with an annotation giving its percentage contribution to the sum. Use a method that takes the entire array as one argument and returns the sum of the numbers in the array. (Hint: Ask the user for the number of integers to be entered, create an array of that length, and then fill the array with the integers read.arrow_forwardJAVA PROGRAM Write a program that asks the user to input two integers a and b. Then create an array that has all integer from a to b. Print out the array. (Don’t forget to consider the situation of a=b, a<b, and a>b.) Example 1: Input two numbers: 6 2 Array is [6, 5, 4, 3, 2] Example 2: Input two numbers: 4 8 Array is [4, 5, 6, 7, 8] Pass the above array as a parameter to a method called average and return the average and print it out in the main method.

- Write a program that declares an array of 15 integers and reads the values from the user. Make sure that the user doesn’t enter a value greater than 10 (if the user enters a value not in the allowed range, discard that value and read another to put into the array). Now tell the number that occur maximum number of times in the array. For example for the following 7 has maximum occurrence. 4,7,3,3,2,7,1,5,7,9,9,9,7,8,10 Use both linear and binary search.arrow_forwardWrite a Java program named Findletter that asks the user to enter 10 letters and store them in an array. Then it should ask the user to enter a letter (char value) to search for it.

- (a)Implement all the classes. The formula for calculating salary for each class is shown below: For the Employee class, salary = basic salary + allowance For the Manager class , salary = basic salary + allowance + travel claims For the Clerk class , salary = basic salary + allowance + overtime pay,where overtime pay = overtime hours x overtime rate. Set overtime rate as RM3.50. Write a client program that creates an array named empArray that stores an object of an Employee,a Manager and a Clerk.In your program, include a method called printElements() that takes an array as parameter and prints the type of employee, the object’s data field values (by invoking thetoString() method) and the monthly salary.arrow_forwardWrite a program called Range_array.java that has a method with one integer array and two integers position1 and position2 as parameters, where 0<=position1<=position2<=a.length-1. The method should construct and return an array that is identical to the given array, but with the values in position1 through position2 deleted.
