Write a Java program that asks the user to enter the size for an Array. Then fill the array with the arithmetic series that starts at 3.5 and goes up by 3. (Hint: use for loop). Display the sum of all the numbers in the array. Display the Average of all the numbers in the array.

for beginning java, here's my assignment " Write a program that ask the user to enter a list of positive scores until the user enters a negative score to terminate the input.  You need to store these scores in an array.   You can assume the maximum number of scores the user may enter is 50.  However, you need to keep track of the actual number of scores entered.  Write 2 methods: 1. calculateAverage(): this method takes the list of scores and return the average score. 2. countPerfectScores(): this method takes the list of scores and return the number of perfect scores (100). The main program reads the input and calls these methods and print the results. Please make sure you write a comment line to document what your method does."   Here is my code, " import java.util.Scanner;class Main {  public static void main(String[] args) {    Scanner sc = new Scanner(System.in);     // Start array for scores    int[] scores = new int[50];    int size = 0;     // Have user enter scores until…

The Lo Shu Magic Square is a grid with 3 rows and 3 columns shown below.             The Lo Shu Magic Square has the following properties: The grid contains the numbers 1 – 9 exactly The sum of each row, each column and each diagonal all add up to the same number. This is shown below: Write a program that simulates a magic square using 3 one dimensional parallel arrays of integer type. Do not use two-dimensional array. Each one the arrays corresponds to a row of the magic square. The program asks the user to enter the values of the magic square row by row and informs the user if the grid is a magic square or not. Processing Requirements - c++ Use the following template to start your project: #include<iostream> using namespace std;   // Global constants const int ROWS = 3;  // The number of rows in the array const int COLS = 3;  // The number of columns in the array const int MIN = 1;  // The value of the smallest number const int MAX = 9;  // The value of the largest number //…

JAVA 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. (Do not use Math library to get the average.)
