Write a solution algorithm to find the average ages of students in a class using a method pseudocode

Write a recursive method that gets three parameters as input: an array of integers called nums, an integer called index, and an integer called value. The purpose of this method is to count how many times value appears in the array starting at nums[index]. Do not use loops. (Java code)

Java - Write an iterative method that calculates the SUM of all integers between 1 and a given integer N (input into the method). Write a corresponding recursive solution. (return answer, don’t print)

Alert dont submit AI generated answer. Write Java program with a recursive method called evenfact(N) which takes in a number N and returns the factorial of the even numbers between the given number N and 2.

For questions 1 – 2, use the following recursive method.public int question1_2(int x, int y){if (x == y) return 0;else return question1_2(x-1, y) + 1;} 2) Calling this method will result in infinite recursion if which condition below is initially true?a) (x = = y)b) (x != y)c) (x > y)d) (x < y)e) (x = = 0 && y != 0)

Write a recursive method called drawTriangle() that outputs lines of '*' to form an upside down isosceles triangle. Method drawTriangle() has one parameter, an integer representing the base length of the triangle. Assume the base length is always odd and less than 20. Output 9 spaces before the first '*' on the last line for correct formatting. Hint: The number of '*' decreases by 2 for every line drawn. Ex: If the input of the program is: 3 the method drawTriangle() outputs: *** * Ex: If the input of the program is: 19 the method drawTriangle() outputs: ******************* ***************** *************** ************* *********** ********* ******* ***** *** * Note: No space is output before the first '*' on the first line when the base length is 19.

I need the code from start to end with no errors and the explanation for the code ObjectivesJava refresher (including file I/O)Use recursionDescriptionFor this project, you get to write a maze solver. A maze is a two dimensional array of chars. Walls are represented as '#'s and ' ' are empty squares. The maze entrance is always in the first row, second column (and will always be an empty square). There will be zero or more exits along the outside perimeter. To be considered an exit, it must be reachable from the entrance. The entrance is not an exit.Here are some example mazes:mazeA7 9# # ###### # #   ## # # #### #     ## ##### ##       ########## RequirementsWrite a MazeSolver class in Java. This program needs to prompt the user for a maze filename and then explore the maze. Display how many exits were found and the positions (not indices) of the valid exits. Your program can display the valid exits found in any order. See the examples below for exact output requirements. Also, record…
