Write java code that recursively calculates the Sum of the array cells. Program requirements: Create an array named MyArr and initialize it as follow: 27 81 243 88 1- Write a method named ArrSum that recursively calculates the Sum of the numbers in the Array and returns the Sum of the numbers. Hint: Method with 1 parameter (the Array) that returns 1 value (the Array's Sum). 2- Write a method named Display that displays the Array contents and Sum of the numbers. 31 19 100 6 10 5

1. Square Roots Create a class with a method that, given an integer, returns an array of double-precision floating point numbers (known in Java as double), each of which is a square root of a number between 2 and the parameter to the method. For example, if the parameter is 5, the method should return an array of 4 doubles, with approximate values 1.4142135623, 1.7320508075, 2.0, and 2.2360679774. Your method should check the validity of the parameter, and take appropriate action if the parameter is invalid. 2. Reading Files Create a class with a method that, given a string representing a file name, returns an integer with the number of characters in the file. For example, if the file has 10 characters, your method must return the number 10. 3. Main Class Create a class HW1.java with a main method that does both of the following: calls the method from part 1 with a random integer between 0 and 10, and prints each of the numbers in the result. The numbers should all be printed on the...

JavaDriver Program Write a driver program that contains a main method and two other methods. Create an Array of Objects In the main method, create an array of Food that holds at least two foods and at least two vegetables. You can decide what data to use. Method: Print Write a method that prints the text representation of the foods in the array in reverse order (meaning from the end of the array to the beginning). Invoke this method from main. Method: Highest Sugar Food Write a method that takes an array of Food objects and finds the Food that has the most sugar. Note that the method is finding the Food, not the grams of sugar. Hint: in looping to find the food, keep track of both the current highest index and value. Invoke this method from main.

In JAVA PROGRAMMING please read details on pictures thank you. (You will need to read in the student data first and then read in the scores) You will open each file and read the information into their respective classes/arrays For each student, you will calculate their lowest score, their highest score, their average, and their grade. For each quiz, you will calculate the lowest score, the highest score, and the average You will create and print an Honor Role. The Honor Role comprises students who received an ‘A’ grade. REPORT WILL LOOK LIKE THIS LastName FirstName StudentID Score 1 Score 2 Score 3 Score 4 Score 5 High Low Average Grade High...

Problem Description - JAVA PROGRAMMING Use a Two-dimensional (3x3) array to solve the following problem: Write an application that inputs nine numbers, each of which is between 1 and 10, inclusive. 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. Example: 1 2 3 4 5 6 7 8 9 the result will be : 1 4 7 2 5 8 3 6 9

How is this program written in java?

Can you write it in Java, add comments Create an application containing an array that stores eight integers. Prompt the user to enter the 8 integers. The application should call five methods that in turn (1) display all the integers, (2) display all the integers in reverse order, (3) display the sum of the integers, (4) display all values less than the calculated average value, and (5) display all values that are higher than the calculated average value. Save the file as ArrayMethodDemo

Exercise #1: Cumulative sum: Write a Java program that prompts the user to enter an integer number (n) that indicates the number of elements of an array (the maximum value for n is 100). Then the user enters n double numbers. The program creates another array of cumulative sums of the first array and outputs it. One decimal place should be used to output the cumulative array. Sample inputs/outputs: Enter the array size: 4 Enter the array elements: 5.0 6.5 7.3 10.2 Cumulative Array: 5.0 11.5 18.8 29.0 Enter the array size: 101 The maximum size is 100! Enter the array size: 5 Enter the array elements: 2.34 5.61 4.67 0.897 Cumulative Array: 2.3 8.0 12.6 19.6 20.4

Java Code Write a Windspeed class that stores the total winsoeed for each of 12 months into an array of double windspeedmeasures. The windspeed shoukd be collected from the user. The program should have methods that return the following: - total windspeed fir the year - the average monthly windspeed (Include single line comments and populating the array with a Scanner)
