- You can declare a void method as follow; public void int calculateSalary() { int num1=89; int num 2= 71; int sum= num1+num2; return sum; } a) True b) FalseJAVA Problem description:You are to write a program called Seasons that prompts the user for a month and day and displays the season in which that date occurs. For reference, we will use the following date cutoffs for the various seasons: Winter December 21 – March 19 Spring March 20th – June 20th Summer June 21st – September 20th Fall September 21st – December 20th Data Validation For this program, you'll write a specific method to perform data validation based on the month and day entered. More specifically: Month – the month entered must be a valid month of the year (January – December). Day – the day entered must be a valid day for that month: January, March, May, July, August, October, December have 1-31 days. April, June, September, November have 1-30 days. February has 1-28 days (do not worry about leap years) Required program decomposition String getMonth(Scanner console) This method is called from the main method and should prompt for the month as a string…JAVA Write a class that calculates add, subtraction, and multiplication. The class should include the following methods: Constructor : initialize all values to 0 getAsk() : Ask users to input two integer numbers. This method calls Distribute() method. Distribute() : Ask users to choose which calculation he/she wants. This method calls a method that can add, subtract, or multiply based on the user's option. CalAdd() : add two numbers CalSub() : subtract two numbers CalProduct() : multiply two numbers toString() : toString method that display result of operation. The program should be designed to test the class developed. Your program might look like the following: public class CalculateNumTesting{ public static void main(String[] args){ CalculateNum calculation = new CalculateNum(); calculation.getAsk(); System.out.println(calculation); } }
- Python Programming only please no java Create a PollMachine class that can be used for a simple poll for users. Your program must perform the following actions: Method to clear the machine state Method to agree/Disagree to 3 options of your choice for example (I enjoy being a student Agree(A)/Disagree(D)) Get tallies of all agrees and disagrees for each answer Keep asking for users to enter answers until the user ends the program. Print the following to the console: Display the results after the poll has ended. Make sure to use a try-except block and include the finally block. Describe the data you print. Do not just print numbers to the screen explain what each number represents.True or False A static method can reference an instance variable.use only C# programming Write a method call CubeIt(int x, ref int cube) that takes two arguments and does not return a value. The method will cube the first argument and assign it to the second argument.In your main, call this method twice and print the value of the parameters after each method call. Write a method with the following header: static void CalculateTuitionFee(int numberOfCourses, double costPerCourse, ref double fees). This method will calculate and assign the required fees amount to the third argument. [Fees = number of courses * cost per course + 15.25].From your program Main() method, call the CalculateTuitionFee () method four times supplying different arguments each time and display the value of the third argument after each method call. Write a method that takes four parameter of type int. The method will assign the sum of the first two arguments to the third and the difference of the first two to the fourth. This method should be coded so that the calling…
