Array Lists & Graphics: Create a project in Eclipse named Blinds. Include two classes: Rainbow and RainbowViewer. Using the colours in Table 1 in any order you want, create a 13 rows x 1 column arrangement of Rectangles (width = 500, height = 50) starting at x = 50, y = 50 with the BLACK square. Use an ArrayList to store the 13 rectangles that form the blinds. [Hint: While creating each rectangle, you can use a for loop. When ready, use the .fill method to paint them onto a JFrame (600x800) with title: “My ColourfulBlinds”.]

Javascript Use a for/of loop to iterate over the array of students. For each student, use a template literal to print out their name, age, and major in a formatted string. (e.g. John is 18 years old and is studying Computer Science.) Within the template literal, use object dot notation to access the name, age, and major properties of the student object. Use a console.log() to print out the formatted string for each student. Test the code by running it and verifying that it prints out the details of each student in a formatted string.============================================================================== const students = [ { name: "John", age: 18, major: "Computer Science" }, { name: "Newton", age: 19, major: "Mathematics" }, { name: "Barry", age: 20, major: "Physics" }, ]; // Iterate through the array of objects students using for/of // Print a message to the console that includes the student's name, age, and major // Example: John is 18 years old and…

Hi, but the answer is incomplete(please see below): f. Create a new StringBuilder Object using no-arg constructor. g. Using for loop append the array elements one by one to the StringBuilder (one per loop iteration) h. Record a run-time it took to append all integers to the StringBuilder (record run-time of 2.g.)) i. Repeat the testing with 500 and 5,000 elements by again creating new integer arrays with 500 and 5000 sizes respectively. j. Record and display the run-time it took to append all integers to the String and StringBuilder respectively. k. Submit the screenshot of results and a small summary in the form of a table below :
GetMonth - This method prompts for and returns the month GetNumMurals - This method prompts for and returns the number of murals scheduled and is called twice -- once for interior murals and once for exterior murals ComputeRevenue - This method accepts the number of interior and exterior murals scheduled, accepts the month they are scheduled, displays the interior and exterior prices, and then returns the total expected revenue DataEntry - This method fills an array with customer names and mural codes and is called twice -- once to fill the array of interior murals and once to fill the array of exterior murals GetSelectedMurals - This method continuously prompts for mural codes and displays jobs of the corresponding type until a sentinel value is entered. In order to prepend the $ to currency values, the program will need to use the CultureInfo.GetCultureInfo method. in C#

Create in Java (1) Create an array of String objects and populate it with the days of the week (7 days)(i.e., Monday - Sunday)(2) Create an array parallel to the one created in (1) to store the entrées. However, you do not have this information, soyou will need to write a loop that prompts the user to enter the entrée served on that day. This prompt shouldinclude the day for which you are asking for the information (e.g., "What entrée is being served on Monday?")(3) Create another parallel array that stores the prices. You will also need to collect this information from the user. Thistime, your prompt should include the name of the entrée for which you are asking for the price(4) Prompt the user to choose an entrée from a list that you display numbered 1 through 7 (have them input a number1 to 7) and search the array and output the day on which the entrée will be served(5) Search through the array for the highest price entrée and output the name of this entrée for the user including…
Lo Shu Magic Square C++ The Lo Shu Magic Square is a grid with 3 rows and 3 columns. The Lo Shu Magic Square has the following properties: The grid contains the numbers 1 through 9, each cell is unique. The sum of each row, each column, and each diagonal all add up to the same number. Write a program that creates a 2D array of size 3x3, and fills each cell withn random, unique values betweem 1 and 9. Print the values. Determine if the 2D array is a Lo Shu Magic Square and print the results. Sample Output Run the program when the 2D array is a lo shu square. A couple runs of the program where it is NOT a Lo Shu Magic Square. The program declares and initializes a 2D array of size 3,3 and fills it with random, unique values. The program prints the values correctly. The program determines whether or not the 2D array is a Lo Shu Magic Square and prints the results. The program must use at least one function besides main for credit.
