Java switch statement find the number of days in a month

Question

We would like to write a program that prompts the user to enter the month and year and displays the number of days in the month.

For example, if the user entered month 2 and year 2012, the program should display that February 2012 had 29 days.

If the user entered month 3 and year 2015, the program should display that March 2015 had 31 days. 

import java.util.Scanner;

public class Main {
   public static void main(String[] args) {
      Scanner input = new Scanner(System.in);

      // Prompt user to enter the month an year
      System.out.print("Enter the month as integer: ");
      int month = input.nextInt();
      System.out.print("Enter the year as integer: ");
      int year = input.nextInt();

      //your code here
   }// www.  java 2 s  .  com
}





import java.util.Scanner;

public class Main {
   public static void main(String[] args) {
      Scanner input = new Scanner(System.in);

      // Prompt user to enter the month an year
      System.out.print("Enter the month as integer: ");
      int month = input.nextInt();
      System.out.print("Enter the year as integer: ");
      int year = input.nextInt();

      boolean leapYear = (year % 4 == 0 && year % 100 != 0) || (year % 400 == 0);
      // Display the number of days in the month
      switch (month) {
      case 1:
         System.out.println("January " + year + " had 31 days");
         break;
      case 2:
         System.out.println("February " + year + " had" + ((leapYear) ? " 29 days" : " 28 days"));
         break;
      case 3:
         System.out.println("March " + year + " had 31 days");
         break;
      case 4:
         System.out.println("April " + year + " had 30 days");
         break;
      case 5:
         System.out.println("May " + year + " had 31 days");
         break;
      case 6:
         System.out.println("June " + year + " had 30 days");
         break;
      case 7:
         System.out.println("July " + year + " had 31 days");
         break;
      case 8:
         System.out.println("August " + year + " had 31 days");
         break;
      case 9:
         System.out.println("September " + year + " had 30 days");
         break;
      case 10:
         System.out.println("October " + year + " had 31 days");
         break;
      case 11:
         System.out.println("November " + year + " had 30 days");
         break;
      case 12:
         System.out.println("December " + year + " had 31 days");
      }
   }
