Can't add to ArrayList within switch statement?

[Ray Michaels]

I'm having trouble inserting objects to an ArrayList within a switch statement. Before entering the switch, the add function works fine. Here's the code:

import java.util.*;

public class AppointmentBook {

	public static class Appointment {
	
		int timeS = 0, timeE = 0, date = 0;
		String description = new String("");
		
		public Appointment(String desc, int day, int start, int end) {
		
			timeS = start;
			timeE = end;
			date = day;
			description = desc;
		}
		
		int getStart() { return timeS; }
		int getEnd() { return timeE; }
		int getDay() { return date; }
		String getDesc() { return description; }
		
		public String toString() { return new String(date + "\t" + timeS + "-" + timeE + "\t" + description); }
	}
	
	public static int linearSearch(ArrayList<Appointment> sorted, Appointment test) {
	
		for(int i = 0; i < sorted.size(); i++) {
		
			if(test.getDay() == sorted.get(i).getDay()) return i;
			else if(test.getDay() < sorted.get(i).getDay() && test.getDay() > sorted.get(i+1).getDay()) return i;
		}
		return sorted.size();
	}
	
	public static void main(String[] args) {
	
		int run = 0;
		
		while (run == 0) {
		
			Scanner input = new Scanner(System.in);
			
			ArrayList<Appointment> appointmentList = new ArrayList<Appointment>();
			appointmentList.add(new Appointment("blah blah blah", 20110408, 1800, 1900)); //works
			
			int timeS, timeE, date;
			String description;
			
			appointmentList.add(new Appointment("blah blah blah", 20110408, 1800, 1900)); //works
			System.out.println("\nAssignment 8\n" + appointmentList.size());
			System.out.println("1. Add an appointment");
			System.out.println("2. Print appointment list");
			System.out.println("3. Exit");
			System.out.print("\nEnter the number corresponding to the task you would like to execute: ");
			int selection = input.nextInt();
			appointmentList.add(new Appointment("blah blah blah", 20110408, 1800, 1900)); //works
			
			while (selection > 3 || selection < 1) { System.out.println("Please input a valid value 1-3"); selection = input.nextInt(); }
			
			switch(selection) {
			
				case(1):
				
					appointmentList.add(new Appointment("blah blah blah", 20110408, 1800, 1900)); //doesn't work
					System.out.print("\nEnter the appointment's desciption: ");
					description = input.next();
					System.out.print("Enter the appointment's date (format: yyyymmdd): ");
					date = input.nextInt();
					System.out.print("Enter the appointment's start time (format: hhmm): ");
					timeS = input.nextInt();
					System.out.print("Enter the appointment's end time (format: hhmm): ");
					timeE = input.nextInt();
					
					
					
					System.out.println("\nPress Enter key to continue"); input = new Scanner(System.in); input.nextLine();
					break;
				
				case(2):
				
					for(int i = 0; i < appointmentList.size(); i++) System.out.println(appointmentList.get(i).toString());
					System.out.println("\nPress Enter key to continue"); input = new Scanner(System.in); input.nextLine();
					break;
				
				case(3): System.out.println("Bye"); run = 1; break;
			}
		}
    }
}

Can anyone advise me as to why the add command within the switch statement isn't working and what to do to make it work?

Hi,

Try removing the () from the case number like this case 1: not case (1):

It might be helpful if you explained what "isn't working" means.

Nothing gets added to the ArrayList... the size doesn't increase after the add statement within the switch and the values added don't show when I print out the contents of the ArrayList. Don't know how to explain it any other way... Removing parenthesis from around the case values did not fix it .

Edit: I've tried removing the switch and using an if instead, but it does not make a difference.
Edit 2: I figured out the problem was that I was instantiating the ArrayList after everytime I tried to add an appointment within the switch.
