Write a program that defines symbolic constants for all seven days of the week. Create an array variable that uses the symbols as initializers.

JAVA I cannot figure this one out no matter what I do I cannot get it to run. Please write it in a student way not in an too advance way. Write an application containing three parallel arrays that hold 10 elements each. The first array hold four-digit student ID numbers, the second array holds first names, and the third array holds the students’ grade point averages. Use dialog boxes to accept a student ID number and display the student’s first name and grade point average. If a match is not found, display an error message that includes the invalid ID number and allow the user to search for a new ID number.

Create a program called array.py that has a function that takes four integer arguments. Those arguments should be put into an Numpy array.  The function will have two print statements.  The first will print the type of the array you create (which should be <class ‘numpy.ndarray’>).  The second will print the multiplication of the four items in your 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…

Please assist with the attached question using Java language. Thanks.

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 //…
