Two-Dimensional Array Instruction: Create a java program that generates elements (randomly from 10 – 75) of a 2-dimensional array (5x5) using the Random Class then perform the following: 1) Output the array elements 2) Output the sum of prime numbers in the array 3) Output the elements in the main diagonal. 4) Output the sum of the elem

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

class Main { // this function will return the number elements in the given range public static int getCountInRange(int[] array, int lower, int upper) { int count = 0; // to count the numbers // this loop will count the numbers in the range for (int i = 0; i < array.length; i++) { // if element is in the range if (array[i] >= lower && array[i] <= upper) count++; } return count; } public static void main(String[] args) { // array int array[] = {1,2,3,4,5,6,7,8,9,0}; // ower and upper range int lower = 1, upper = 9; // throwing an exception...

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

void changeAll(int x[]) { x[0] = x[0] + 5; return; The first element in an array would be increased by 5 The array would be the same because it was passed by value x would be increased by 5 All the elements in the passed array would be incremented by 5

Recipe Program - Java ONLYI am looking to create a program that is a recipe holder. It needs to include at a minimum: At least 1 loop An Array or ArrayList At least 3 Java classes Use of methods The program would allow the user to (as part of a menu selection): Add a recipe Include ingredient list Instructions List all recipes that are in the program (array) Display a single recipe Search Recipes (option to view recipe selected) For example, searching for peanut butter cookie would bring up the recipe or multiple if the same name. The user could then select one of them to view the recipe. Search Recipes with a single ingredient (option to view recipe selected) For example: search for coconut and it would bring up coconut cream pie and German chocolate cake. The user could then select one of them to view the recipe. Close application Also need the program in a UML diagram.
