c# Write a method which does not take any parameters and does not return a value. The method name is MyMethod which will calculate the sum of 2, 4, 6, ... , 20 together using a while loop, and display the result as "The sum is NNN.". (NNN will be replaced by the real sum value.)

In python Add the following four methods to your Crew class: move(self, location): This takes in a location as a string, along with self, and attempts to move the crew member to the specified location. If location is one of the five valid location options ("Bridge", "Medbay", "Engine", "Lasers", or "Sleep Pods"), then this should change self.location to that new value. Otherwise, the function should print out the message: Not a valid location. repair(self, ship): first_aid(self, ship): fire_lasers(self, ship, target_ship, target_location): The above three methods represent tasks that a basic Crew member is not capable of (but one of its derived classes will be able to accomplish). So each of them should simply print out a message of the form: <Name> doesn't know how to do that. Examples: Copy the following if __name__ == "__main__" block into your hw12.py file, and comment out tests for parts of the class you haven’t implemented yet. if __name__ == '__main__': crew1...

X609: Magic Date A magic date is one when written in the following format, the month times the date equals the year e.g. 6/10/60. Write code that figures out if a user entered date is a magic date. The dates must be between 1 - 31, inclusive and the months between 1 - 12, inclusive. Let the user know whether they entered a magic date. If the input parameters are not valid, return false. Examples: magicDate(6, 10, 60) -> true magicDate(50, 12, 600) –> false

in this code, the integer on each line shows the line number that is not part of code: what are the parameters of sum: ____ 1 public static int sum(int x, int y){ 2 int z = x +y; 3 return z; 4 } 5 public static void main(String[] args){ 6 ... 7 sum(a+2, b); 8 ... 9 }

Python Programming ONLY PLEASE NO JAVA Use recursion to determine the number of digits in an integer n. Hint: If n is < 10, it has one digit. Otherwise, it has one more digit than n / 10. Write the method and then write a test program to test the method Your test program must: Ask the user for a number Print the number of digits in that number. (describe the numbers printed to the console) Use program headers and method header comments in your code.

Repeating String Write a method that takes a String and an int and return a String that is the original String repeated n times. For example, repeatString("Famous", 3) should return "FamousFamousFamous" The method signature should be public String repeatString(String str, int n) public String repeatString(String str, int n) { //declare a string variable //set up statements for repeating n number of times //create the appropriate return statement }
