Explanation / Answer
// Import statements
import java.util.Scanner;
public class SelectionSwitchDemo
{
public static void main(String[] args)
{
// Display a Welcome note
System.out.println("Welcome to the Switch Demo");
// Variables to hold values
int month = 0;
int numDays = 0;
// Use the Scanner class to input data
Scanner scannerIn = new Scanner(System.in);
System.out.println("Enter the Month (1-12):");
// the nextInt() method scans the next int value
month = scannerIn.nextInt();
// Verify the month was entered
System.out.println("The following month was entered " + month);
// Selection statement to determine number // of days in month
if( (month == 1) || (month == 3) || (month == 5) || (month == 7) || (month == 8) || (month == 10) || (month == 12) )
{
numDays = 31;
}
else if (month == 2)
{
numDays = 28;
}
else if ((month == 4) || (month == 6) || (month == 9) || (month == 11) )
{
numDays = 30;
}
// Selection statement to determine Birthday and Holiday Greetings
switch (month)
{
case 1:
// Print out January Events
System.out.println("Happy New Year!");
System.out.println("Celebrate Martin Luther King's Birthday!");
System.out.println("Happy Birthday to my niece Erica!");
break;
case 2: // Print out February Events
System.out.println("Happy Valentine's Day!");
System.out.println("Happy President's Day!");
System.out.println("Huge Birthday wishes to my son Elijah and niece Jelissa!");
break;
case 3: // Print out March Events
System.out.println("Enjoy St. Patrick's Day!");
System.out.println("Let's celebrate my sister Rondi Birthday!");
System.out.println("HAPPY 4th BIRTHDAY TO MY GRANDSON MONTY!");
break;
case 4: // Print out April Events
System.out.println("Thomas Jefferson was born in April!");
break;
case 5: // Print out May Events
System.out.println("Enjoy Memorial Day!");
System.out.println("Don't forget to Celebrate with Mom!");
System.out.println("Singing Birthday praises to my oldest sister Chelle!");
break;
case 6: // Print out June Events
System.out.println("Happy Father's Day!");
break;
case 7: // Print out July Events
System.out.println("Happy 4th of July!");
System.out.println("It's Your Birthday, Happy Birthday to AMIRAH and to Eric! She's my daughter, he's my brother, and it's their birthday!");
break;
case 8: // Print out August Events
System.out.println("Barack Obama was born in August! Happy Birthday Pres");
break;
case 9: // Print out September Events
System.out.println("Celebrate Labor Day!");
System.out.println("Let's Drink to my sister Jewel's Birthday! Happy Birthday!");
break;
case 10: // Print out October Events
System.out.println("Happy Halloween!");
System.out.println("Have a scary Birthday October Boos!");
break;
case 11: // Print out November Events
System.out.println("Happy Thanksgiving Day!");
System.out.println("Remember to Thank a Vet!");
System.out.println("Happy Birthday to November Babies!");
break;
case 12: // Print out December Events
System.out.println("Enjoy those Holidays with Family!");
System.out.println("Celebrate Martin Luther King's Birthday!");
break;
default: System.out.println("Month is not a value between 1 and 12");
// Exit the application for invalid Months
System.exit(0);
}
// Output the number of days in the selected month
System.out.println("Number of Days in month " + month + " is " + numDays);
}
}
Output:
Welcome to the Switch Demo
Enter the Month (1-12): 12
The following month was entered 12
Enjoy those Holidays with Family!
Celebrate Martin Luther King's Birthday!
Number of Days in month 12 is 31
