help on a program

Copy linkTweet thisAlerts:
Oct 01.2006

Program Description:
Given an input data file containing dates, one date per line, write a Java application Project.java which
will read lines of text from data file and put them into a partially-filled array of strings, and will then print
the contents of the array to a series of three JOptionPane message dialog boxes with text areas. The
first message box will display a column of the dates in the original order in which they were listed in the
file. The second message box will display a column of the dates sorted in lexicographical order, as
strings. The third message box will display a column of the dates in ascending order by date (earliest
date first).

@Khalid_AliOct 02.2006 — if you want to learn the language then you will have to do a bit better then this...

@james12authorOct 02.2006 — ok, here' what i understood and did, so now you guys help me out,

mport javax.swing.*;

public class pro1111

{

public static void main (String [] args)

{

TextFileInput in = new TextFileInput("Dates.txt");
TextFileOutput out = new TextFileOutput("Dates1.txt");

String line = in.readLine();
while ( line != null ) {
StringTokenizer st = new StringTokenizer(line, "/");
int monthNumber = Integer.parseInt(st.nextToken());
int day = Integer.parseInt(st.nextToken());
int year = Integer.parseInt(st.nextToken());
out.println(monthNumberToName(monthNumber)
+ " " + day + ", " + year);

line = in.readLine();
}

}

private static compareDate(string date1, string date2)

{

String date1 = "09/27/2004";

String date2 = "05/04/2002";

if (compareDate(date1, date2) < 0)

System.out.println("date1 is earlier than date2.");

return 0;

}

private static void display(short[] numbers,

int lengthFilled)

{

final String lineBreak = System.getProperty("line.separator");

// Create text area for output:
JTextArea textArea = new JTextArea();
textArea.setEditable(false);

// Print numbers to output text area:
for ( int i = 0; i < lengthFilled; i++ )
textArea.append(numbers[i] + lineBreak);

// Display the output text area via a message dialog box:
JOptionPane.showMessageDialog(null, textArea);
}

@WaylanderOct 03.2006 — Doesnt really work like that hey, someone may do it but its a bit much to ask really.

Why dont you start at the top of the program and try to finish it your self.

Then if you run into a problem ask a specific question about the problem.

Waylander.

@agent_x91Oct 03.2006 — For a start, the first line has a typo in it:


mport javax.swing.*;
[/QUOTE]

Should be [I]import[/I] javax.swing.*

?

@saeOct 04.2006 — We are not going to do your homework for you. As Waylander said, try it yourself and if you have a specific problem then ask. I don't think anyone here would have a problem answering specific questions. We would also gladly help you if you are having problems compiling.

I quickly went over you code and found another error.

System.out.println("date1 is earlier than date2.");
[/quote]
The above code will print exact what is in quotes. As date1 and date2 are variables, you want to make the code like this:
<i>
</i>System.out.println(date1 + " is earlier than " + date2);

@WaylanderOct 05.2006 — Someone delete this thread.
Copy linkTweet thisAlerts:
@agent_x91Oct 09.2006 — Try it for yoruself and we'll help you fix any problems you may have. But I for one am [B]not[/B] going to make an entire program for you because you can't be bothered to do your homework.

Success!
