Question

This is in java, thank you!

Problem2: In this problem you ask the user for a month and day. You will then calculate the season based on the month and day.

• Create a class named Problem2
  • Create two integer instance variables, month and day.
  • Create a constructor to initialize the both variables. The constructor should accept two arguments as parameters, m and d. Initialize the instance variables with these two values.
  • Create a method called calcSeason. It should not have any arguments and should return a string.
  • The method should implement the following algorithm:
    • If month is 1,2, or 3, season = “Winter”
    • Else if month is 4,5, or 6, season = “Spring”
    • Else if month is 7,8, or 9, season = “Summer”
    • Else season = “Fall”
    • If month is evenly divisible by 3 and day >=21, then
      • If season is “Winter” then season = “Spring”
      • Else if season is “Spring”, season = “Summer”
      • Else if season is “Summer” season = “Fall”
      • Else season = “Winter
    • Return Season
  • Create a class named Problem2Tester (reminder: all tester classes have a main method)
    • Import Scanner
    • Create a Scanner object
    • Prompt the use to enter a month as a number
    • Get the number from the user and store it as a variable
    • Prompt the use to enter a day as a number
    • Get the number from the user and store it as a variable
    • Create a Problem2 object, initializing with the month and day from the user
    • Call the calcSeason method and print the result this can be done directly in the print statement or you can create a new variable and print it)

Answer 1

Below is the source code for the two classes:

1. Problem2 class:

/*
* class for calculating the season
*/
public class Problem2 {
   //month and day variables
   private int month;
   private int day;
  
   //constructor
   public Problem2(int m, int d) {
       month = m;
       day = d;
   }
   /*
   * Method to calculate the season
   */
   public String calcSeason() {
       String season = "";
      
       if ((month == 1) || (month == 2) || (month == 3)) {
           season = "Winter";
       }
       else if ((month == 4) || (month == 5) || (month == 6)) {
           season = "Spring";
       }
       else if ((month == 7) || (month == 8) || (month == 9)) {
           season = "Summer";
       }
       else {
           season = "Fall";
       }
       //if month is divisible by 3 and day is greater than or equal to 21
       if ((month%3 == 0) && (day >= 21)) {
           if (season == "Winter") {
               season = "Spring";
           }
           else if (season == "Spring") {
               season = "Summer";
           }
           else if (season == "Summer") {
               season = "Fall";
           }
           else {
               season = "Winter";
           }
       }
       return season;
   }
}

2. Problem2Tester Class:

import java.util.Scanner;
/**
* Class for testing the Problem2
*/
public class Problem2Tester {
   public static void main(String[] args) {
       Scanner sc = new Scanner(System.in);
       System.out.println("Print the month as number: ");
       int month = sc.nextInt();
       System.out.println("Print the day as number: ");
       int day = sc.nextInt();
       Problem2 pr = new Problem2(month, day);
       System.out.println("Season is: " + pr.calcSeason());
   }
}
