Problem
Create a program that allows the user to enter a month, and then outputs the number of days in that month. For simplicity sake, ask the user for the number of the month rather than the string. Also, assume there are 28 days in February. Use JOptionPane.showInputDialog to capture the input, and System.out.println to generate the output. Make sure the user enters a valid month (1-12). If they enter a number that is not in that range, output "Invalid Month". If the user enters a non-integer, let the program crash.
For example, if they want to know how many days there are in the month of January, the user would enter the number 1 and receive an answer of 31.

/* Class DaysInAMonth

*/
// Need this for JOptionPane

{

{
// These variables are used for input
String input;
int month;
// Get input from user
input = JOptionPane.showInputDialog(null, "Please enter a month in number format (1-12).");
// Convert string to integer
month = Integer.parseInt(input);
if( month == 1 || month == 3 || month == 5 || month == 7 ||
month == 8 || month == 10 || month == 12 ) // Months that have 31 days
{
System.out.println("This month has 31 days.");
}
else if( month == 4 || month == 6 || month == 9 || month == 11 ) // Months that have 30 days
{
System.out.println("This month has 30 days.");
}
else if( month == 2 ) // February has 28 days
{
System.out.println("This month has 28 days.");
}
else // Not a valid month
{
System.out.println("Invalid Month.");
}
}
