    Default Code help

    Trying to write a code that store email addresses and phone numbers. I know I am missing a lot but have no idea how to do it.

    <package AddressBookEntryApp;
     
    	import java.io.BufferedWriter;
        import java.io.FileWriter;
        import java.io.IOException;
        import java.util.Scanner;
     
        import javax.swing.JOptionPane;
     
    	public class AddressBookEntry 
    	{
     
    		/**
    		 * @param args
    		 */
     
    		// save an AddressBookEntry object to the file
    		public static void saveEntry(AddressBookEntry entry) 
    		{
     
    		}	
     
    		public static void main(String[] args)
     
    		{
     
    			int listEntries;		// to look up name
    			int addEntry;			// add new name and information into system
    			int exit;				// to exit the system
     
    		    //Print out the welcome screen
    			System.out.println("Welcome to the Address Book application");
    			System.out.println();
     
    			//Asks user to input new email address & phone number.
    			String email = JOptionPane.showInputDialog("Enter list entries:");
    			String PW = JOptionPane.showInputDialog("Enter add entry:");
     
    			try
    			{
     
    			String info = null;
    			BufferedWriter out = new BufferedWriter(new FileWriter(info));
     
    			out.write("------------------");
    			out.newLine();
    			out.write("E-mail: " + email);
    			out.newLine();
    			out.write("Phone number: " + PN);
    			out.newLine();
    			out.write("------------------");
    			out.close();
     
    			}catch(IOException e) {}
    			System.exit(0);
     
     
    			}
    	}

    Can you explain what your problem is?

    One thing you should put in your code is a call to the printStackTrace() method in the catch block so that you will get an error message if there is an exception.

    What I am trying to do is to store email address and phone numbers in this program. the console should come up with 1 - list entry, 2- add entry and 3 exit, then i would click the number of what i want to do. But can't get passed the welcome part.

    What values are returned by the calls to the showInputDialog() methods when you call them?
    Use println statements to print out the Strings' values to see what the user has entered.

    The code you posted does not compile without errors. You need to fix the compiler errors before you can execute the code.
