[SOLVED] Help with if...else...

[lcrakel87]

This program has been driving me nuts. I cannot get a clean compile. The more I look at, the more I just want to completely forget about it. Could someone take a look at it and see if you notice anything wrong?

import java.io.*;

public class ifExample {
	public static void main (String Args[]) throws IOException {
		String day;
		String name = ("Jamie Ambrose");
		String monday = ("\n --Monday Schedule-- \n MA103 11:00am - 12:15pm \n PS101 2:00pm - 3:15pm");
		String tuesday = ("\n --Tuesday Schedule-- \n CIS106 2:00pm - 3:15pm \n PC103 5:00pm - 7:15pm");
		String wenesday = ("\n --Wednesday Schedule--\n MA103 11:00am - 12:15pm \n PS101 2:00pm - 3:15pm");
		String thursday = ("\n --Thursday Schedule--\n CIS106 2:00pm - 3:15pm");
		String friday = ("\n No class today");

	try {

			BufferedReader bf = BufferedReader (new InputStreamReader(System.in));
			System.out.println("Enter the day of week you would like to view: \n Monday-1 \n Tuesday-2 \n Wednesday \n Tursday-3 \n Friday-4");
			day = bf.readLine();
			int daynum = Integer.parseInt(day);
		}

		catch (IOException ioe) {
		System.out.println("IO exception Occurred");
		}



		if ( daynum == 1)
		    {
				 System.out.println(name + "Todays Scheudle" + 1);
			}

		else if ( daynum == 2)
			{
				System.out.println(name + "Todays Schedule" + 2);
			}
		else if (daynum == 3)
			{
				System.out.println(name + "Todays Schedule" + 3);
			}

		else if (daynum == 4)
			{
				System.out.println(name + "Todays Schedule" + 4);
			}

		else if (daynum == 5)
			{
				System.out.println(name + "Todays Schedule" + 5);
			}

		else {
				System.out.println("Enter valid number");
			}

		}
	}

and the errors:

BufferedReader bf = BufferedReader (new InputStreamReader(System.in));

shall be

BufferedReader bf = new BufferedReader (new InputStreamReader(System.in));

The whole code should look like this

import java.io.*;

public class ifExample
{
    public static void main(String Args[]) throws IOException
    {
        String day;
        String name = ("Jamie Ambrose");
        String monday = ("\n --Monday Schedule-- \n MA103 11:00am - 12:15pm \n PS101 2:00pm - 3:15pm");
        String tuesday = ("\n --Tuesday Schedule-- \n CIS106 2:00pm - 3:15pm \n PC103 5:00pm - 7:15pm");
        String wenesday = ("\n --Wednesday Schedule--\n MA103 11:00am - 12:15pm \n PS101 2:00pm - 3:15pm");
        String thursday = ("\n --Thursday Schedule--\n CIS106 2:00pm - 3:15pm");
        String friday = ("\n No class today");

        try
        {
            BufferedReader bf = new BufferedReader(new InputStreamReader(System.in));
            System.out
                .println("Enter the day of week you would like to view: \n Monday-1 \n Tuesday-2 \n Wednesday \n Tursday-3 \n Friday-4");
            day = bf.readLine();
            int daynum = Integer.parseInt(day);

            if (daynum == 1)
            {
                System.out.println(name + "Todays Scheudle" + 1);
            }

            else if (daynum == 2)
            {
                System.out.println(name + "Todays Schedule" + 2);
            }
            else if (daynum == 3)
            {
                System.out.println(name + "Todays Schedule" + 3);
            }

            else if (daynum == 4)
            {
                System.out.println(name + "Todays Schedule" + 4);
            }

            else if (daynum == 5)
            {
                System.out.println(name + "Todays Schedule" + 5);
            }

            else
            {
                System.out.println("Enter valid number");
            }
        }
        catch (IOException ioe)
        {
            System.out.println("IO exception Occurred");
        }
    }
}

If you declare the daynum variable inside the try/catch you should use it there.

Awesome. Thank you. Now its time to convert it to an applet. Hopefully this goes a lot smoother.
