Hey guys. I wanted to know if someone can tell me what's wrong with my code. I got it to work, to a point. It shows all the months, however, when a user inputs the month/number it ends. Which it needs to playback the month... Example: 2 = March

Here's the code

import java.util.Scanner;

public class MonthDemo
{
   public static void main(String[] args)
   {
      // Use the no-arg constructor.
      Month object1 = new Month();
      System.out.println("Month " + object1.getMonthNumber() +
                         " = " + object1);
	  Month object2 = new Month(2);
	  for (int i = 1; i <= 12; i++)
      {
         object2.setMonthNumber(i);
         System.out.println("Month " + object2.getMonthNumber() +
                         " name is " + object2);
      }
		
		String mName;
		Scanner keyboard = new Scanner(System.in);
		Month object5 = new Month("January");
		
		System.out.println("Enter a month name: ");
		mName = keyboard.nextLine();
		System.out.println(object5.mName());
   }
}

And the other part...

Line 25: System.out.println(object5.mName()); , I doubt that the Month class has a method mName() .
What errors do you get and what are you trying to do?

Trying to get it where the user inputs either a number, or the month. And it will show both the month and the number... I tried to take out the mName thing... but it only shows all the months and numbers... then lets the user input, then it cancels for some reason.

Your main should look like:

public static void main(String[] args) {
        // Use the no-arg constructor.
        Month object1 = new Month();
        System.out.println("Month " + object1.getMonthNumber()
                + " = " + object1);
        Month object2 = new Month(2);
        for (int i = 1; i <= 12; i++) {
            object2.setMonthNumber(i);
            System.out.println("Month " + object2.getMonthNumber()
                    + " name is " + object2);
        }

        System.out.println("Enter a month name/Number or Q to quitte: ");
        Month object5;

        while (true) {
            Scanner keyboard = new Scanner(System.in);
            int intMonth;
            String strMonth = keyboard.next();
            if (strMonth.equals("Q")) {
                break;
            }
            try {
                intMonth = Integer.parseInt(strMonth);
                object5 = new Month(intMonth);
                System.out.println(object5.getMonthName());
            } catch (Exception e) {
                object5 = new Month(strMonth);
                System.out.println(object5.getMonthNumber());
            }

        }

    }

This will retrives the month name if you type a number and the month number if you type a month name and will exit if you type "Q".
Hope it helps
