Write a program that lets the user enter the total rainfall for each of 12 months (starting with January) into an array of doubles.
The program should calculate and display (in this order):
the total rainfall for the year,
the average monthly rainfall,
and the months with the highest and lowest amounts.
Months should be expressed as English names for months in the Gregorian calendar, i.e.: January, February, March, April, May, June, July, August, September, October, November, December.
Do not accept negative numbers for monthly rainfall figures.
When a negative value is entered, the program outputs "invalid data (negative rainfall) -- retry" and attempts to reread the value.
NOTE: Decimal values should be displayed using default precision, i.e. do not specify precision.
5. Write a Python function that inputs an array of integers and returns the maximum value in this array. Do not use the max method on array class.
6. Write a Python program that inputs a sentence string by the user and counts the number of words in the sentence
RetailItem Class
Write a class named Retailltem that holds data about an item in a retail store. The class
should have the following fields:
• description. The description field references a String object that holds a brief
description of the item.
• unitsOnHand. The unitsOnHand field is an int variable that holds the number of units
currently in inventory.
• price. The price field is a double that holds the item's retail price.
Write a constructor that accepts arguments for each field, appropriate mutator methods
that store values in these fields, and accessor methods that return the values in these fields.
Once you have written the class, write a separate program that creates three RetailItem
objects and stores the following data in them:
Description
Units on Hand
Price
Item #1
Jacket
12
59.95
Irem #2
Designer Jeans
34.95
[rem #3

- ANSWER IN JAVA: Write an application that inputs five numbers, each between 10 and 100, inclusive. As each number is read, display it only if it’s not a duplicate of a number already read. Provide for the “worst case,” in which all five numbers are different. Use the smallest possible array to solve this problem. Display the complete set of unique values input after the user enters each new value.

Rotate Left k cells Use Python Consider an array named source. Write a method/function named rotateLeft( source, k) that rotates all the elements of the source array to the left by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] rotateLeft(source,3) After calling rotateLeft(source,3), printing the array should give the output as: [ 40, 50, 60, 10, 20, 30]arrow_forwardBY Dr.java : Using methods and arrays, write a program that Creates an array A of size 100 integers. Enter a set of values to fill the array. The values should be within the range 50 to 65 inclusive. If an incorrect value has been entered then the program should display a message asking the user to re-enter the value again. Find the average of the values that are divisible by 7.arrow_forward
- A positive integer greater than 1 is said to be prime if it has no divisors other than 1 and itself. Write a program that asks the user to input an integer greater than 1, then display all of the prime numbers that less than or equal to the number entered. The program should work as follows: • Once the user has entered a number, the program should display an array with all of the integers from 2 up through the value entered. • The program should then use a loop to step through the array. The loop should pass each element to a method that displays the element whether it is prime number. Your result should look like, for example: Enter an integer greater than 1: 9 2, 3, 4, 5, 6, 7, 8, 9 2 is prime 3 is prime 4 is not prime 5 is prime 6 is not prime 7 is prime 8 is not prime 9 is not prime Using java programmingarrow_forwardTake an array of size 10 from user and display the message “This is in array” if a number given by user is in the array.arrow_forward4.

- C++ : You are given an array of integers representing asteroids in a row. For each asteroid in the array/row, the absolute value represents its size, and the sign represents its direction (positive meaning right, negative meaning left). Each asteroid moves at the same speed. Find out the state of the asteroids after all collisions. If two asteroids meet, the smaller one will explode. If both are the same size, both will explode. Two asteroids moving in the same direction will never meet. Example 1: Input: asteroids = [5,10,-5] Output: [5,10] Explanation: The 10 and -5 collide resulting in 10. The 5 and 10 never collide. Example 2: Input: asteroids = [8,-8] Output: [] Explanation: The 8 and -8 collide exploding each other. Example 3: Input: asteroids = [-2,-1,1,2] Output: [-2,-1,1,2] Explanation: The -2 and -1 are moving left, while the 1 and 2 are moving right. Asteroids moving the same direction never meet, so no asteroids will meet each other. Write a C++ program…arrow_forward8. A magic square is an n by n square in which each element is an integer between 1 and n*n and all column sums, row sums and diagonal sums are equal. For example, the following is a 3 by 3 magic square in which each row, each column, and each diagonal adds up to 15. 4 3 8 9 1 7 6. Write a program that accepts a two-dimensional array size 10 by 10. The program should check and output whether it is a magic square or not.

Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations. Remember to validate the input and display an error message if the user inputs invalid data. Documentation and the screenshot(s) of the results.
