Write a program to store multiple memos in a file. Allow a user to enter a topic

Question

Write a program to store multiple memos in a file. Allow a user to enter a topic and the text of a memo (the text of the memo is stored as a single line and thus cannot contain a return character). Store the topic, the date stamp of the memo, and the memo message.

Creating a java.util.Date object with no arguments will initialize the Date object to the current time and date. A date stamp is obtained by calling the Date.toString() method.

Use a text editor to view the contents of the output and to check that the information is stored correctly.

Part of the program code has been provided for you:

Explanation / Answer

import java.io.File;

import java.io.FileNotFoundException;

import java.io.PrintWriter;

import java.sql.Timestamp;

import java.util.Date;

import java.util.Scanner;

public class MemoPadCreator

{

   public static void main(String[] args) throws FileNotFoundException

   {

Date now = new Date();

Scanner console = new Scanner(System.in);

System.out.print("Output file: ");

String filename = console.nextLine();

PrintWriter out = new PrintWriter(new File(filename));

boolean done = false;

while (!done)

{

   System.out.println("Memo topic (enter -1 to end):");

   String topic = console.nextLine();

   if (topic.equals("-1"))

   {

done = true;

   }

   else

   {

System.out.println("Memo text:");

String message = console.nextLine();

// Create the new date object and obtain a dateStamp

now = new Date();

Timestamp dateStamp = new Timestamp(now.getTime());

out.println(topic + " " + dateStamp + " " + message);

   }

}

// Close the output file

out.close();

   }

}
