- For this exercise, you will create several recursive functions in order to get a better understanding of how recursion works. In exercise 2, we will illustrate using recursion for creating art. Create a new project in IntelliJ called Recursion. Add a new Java class called Recursion with a public static main function. You will add several functions to your Recursion class as follows: 1 Write a recursive function int sum(int n) that adds up the numbers from n to 1 and print your result. For example from main do the following: Recursion recursion = new Recursion();System.out.println(recursion.sum(6)); 1.2 Write a recursive function factorial(int n) that calculates the factorial of n. Print out the results. Add your function to your Recursion class. 1.3. Write a recursive function powerOf10(int n) that calculates 10n. 1.4. Write a more general recursive function powerOfN(int x, int p) that calculates the power of xp. Do not use the Math.pow function. 1.5.…Have a research on the use of the Math methods and write a program that uses Math method. Use at least 10 methods. Using recursion, write a program that tells whether a number is palindrome or not Write a Java program that determines whether a positive integer is a prime number. Use a method that reads positive integer, second method that returns true if the number is prime; otherwise returns false and a method that prints a message telling whether is a prime number or not. Sample Output: Positive Integer: 73 73 is a prime number Have a research on the use of the Date and Time methods and write a program that uses Date and Time method. Use at least 3. Have a research on the use of the String methods and write a program that uses String method. Use at least 10.Q2: Write a complete program to test java.util Methods for Arrays and Random Numbers explained in lectures. Note: write the comments that explain all instructions of the program data structures. *
- Java Script There is a single operator in JavaScript, capable of providing the remainder of a division operation. Two numbers are passed as parameters. The first parameter divided by the second parameter will have a remainder, possibly zero. Return that value. Examples remainder(1, 3) → 1 remainder(3, 4) → 3 remainder(-9, 45) → -9 remainder(5, 5) → 0 Notes The tests only use positive and negative integers. Don't forget to return the result.The following class starts to define a Complex number as two numeric (int or float) values, which specify the real and imaginary parts of the Complex number. For example, we can write x = Complex(1,2) to represent the complex number 1+2i (with real part 1 and imaginary part 2) and y = Complex (2,-3) to represent the complex number 2-3i (with real part 2 and imaginary part -3). In the Complex class below, overload(a) the method called by the repr function, producing the standard result (b) the method called by the str function: the correct sign (+ or -) must appear between the real and imaginary parts: for x and y above, str(x) returns '1+2i' and str(y) returns '2-3i'. For Complex(0,0) it returns '0+0i' (c) the addition operator: we can compute the sum of two complex numbers or the sum of a complex number and an int or float (these two types are pure real: each has 0 as its imaginary part) by adding the real parts of each and adding the imaginary parts; 2+3i plus 1+2i is 3+5i; likewise,…I already have the code for the assignment below, but the code has an error in the driver class. Please help me fix it. The assignment: Make a recursive method for factoring an integer n. First, find a factor f, then recursively factor n / f. This assignment needs a resource class and a driver class. The resource class and the driver class need to be in two separate files. The resource class will contain all of the methods and the driver class only needs to call the methods. The driver class needs to have only 5 lines of code The code of the resource class: import java.util.ArrayList;import java.util.List; public class U10E03R{ // Recursive function to // print factors of a number public static void factors(int n, int i) { // Checking if the number is less than N if (i <= n) { if (n % i == 0) { System.out.print(i + " "); } // Calling the function recursively // for the next number factors(n, i +…

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.
