- 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 9arrow_forwardDesign a program that asks the user to enter a store’s sales for each day of a 7 day week. The amounts should be stored in an array. Use a loop to calculate the total sales for the week, the average sales per day, and also display the list of values. This is for java.arrow_forwardIn javacode: Use ArrayList to create an array called myAL of type integer. --Fill the array with the values 5, 10, 15, 22, 33. --Print the array (use enhanced for loop). --Insert the value 25 between 10 and 15 and print the array.--Remove 2 elements on index 1 and 3 and then print the array.--Print if the array contains the value 123 or not.--Print the index of the element 22.--Print the size of the array.arrow_forward
- Part 2: Coding 1. Write a complete Java program named FindAverage that contains the following: a. A main method that asks the user to provide the number of rows and columns for a 2- dimensional array of integers. b. A main method calls the getArray() method that creates the 2D array of specified size and populates it with random values from 0 to 100. c. A main method prints the elements of the 2D array created by getArray(). d. A main method calls the printAverage method that will: i. Receive the two-dimensional array as input ii. Calculate the average of elements in this array iii. Display the average on the console. The average of all elements should be formatted as xxx.XX. Hint: you can print the 2D array at any point in the program using either traditional for loop, foreach loop or available methods in java.util package. e. Add comments to your program. Start your program with the following header: *** *** ***** /**** ***arrow_forward/*** creates an array of 1000 integers where each element matches its index* * @return the array that is created*/public static int[] makeNumberArray() {arrow_forwardPlease assist with the attached question using Java language.
