Java programming problem
 
Ok I have a litle problem I am trying to write a program that does the following on this pdf.

This is what I have for code...btw i'm using jbuilderx

package test;

import javax.swing.*;
import java.lang.Date;

/**

*/

public class Untitled1 {
public Untitled1() {
}
public static void main(String[] args) {
Untitled1 untitled11 = new Untitled1();
String whatisyourName;

whatisyourName = JOptionPane.showInputDialog(null,
"What is your name?");

JOptionPane.showMessageDialog(null,
"" + whatisyourName + date);

String date;
Date today;
today = new Date ( );
date = new SimpleDateFormat ( "MM/dd/yy*)

}

}

you pretty much have 2/3 of it done already. What you still need to do though is remember where you create your variables.

The second JOptionPane is referencing date which hasnt been created yet. Also doing: whatisyourName + date will give you something like MyName04/36/93 which isn't very nice looking at all. Might wish to clean up your formatting a bit.

another pointer, you may be able to just add the date like you currently have, but check to see if there is a date.toString() function. More than likely there is. Since it is an object, it doesnt necessarily mean it will give you a pretty string when appending it to a String.

Eeew SWING, I am so glad I am done with programming classes. Like oblar said watch out about where you your initialize and set your variables (date is set after you use it). Also, you are trying to cast a SimpleDateFormat to a String which will not work. You will want to do something like this:

SimpleDateFormat myDateFormat = new SimpleDateFormat ( "MM/dd/yy" );
date = myDateFormat.format( today );

I also don't think the toString on a Date will give you a nicely formatted date, instead, I beleive it will return a Long representing the number of milliseconds since the epoch. That should get you back on track a bit.

Thanks for the help so far.....too bad I still have no fucking clue about the date command....oh well if i fail...

Date took me awhile too. It is tricky as shit with all it's different forms and formatting. And YOU WILL NOT FAIL. Just keep posting your code here and we will make sure you won't fail. From the PDF it looks like you got some time left.

public class Untitled1 {
public Untitled1() {
}
public static void main(String[] args) {
Untitled1 untitled11 = new Untitled1();
String whatisyourName;

whatisyourName = JOptionPane.showInputDialog(null,
"What is your name?");

JOptionPane.showMessageDialog(null,
"" + whatisyourName + datetoday);

String title = datetoday;
Date dateformat = new
SimpleDateFormat "date" = new SimpleDateFormat ( "MM/dd/yy" );
date = myDateFormat.format( today );


}

}
Ok this is what I have so far...and the "date" that I have in bold is an error I have is '(' or '[' expected at line 31 (31:19), Making the other window pop up on the end of the assignment will be easy but this is the tough part so far

Couple problems:

You're still using varaibles before they're even created. You need to move the date formatting and strings block of codes before displaying the user name and date.

What is String title = datetoday;? datetoday doesn't even exist yet! And it's not a string.

In the line date = myDateFormat.format( today ); The variable today and myDateFormat doesn't even exist yet.

There's a total of 3 variables that are being used that hasn't been intialized yet. And 1 variable that isn't even being used at all

That's from looking at your recent coding.

From your first post:

String date;
Date today;
today = new Date ( );
date = new SimpleDateFormat ( "MM/dd/yy*)

This block of code is better than what you have now. The only problem with it is that the date = new SimpleDateFormat ( "MM/dd/yy*) line is in error. date is already a String type, not a SimpleDateFormat. So, either you change the line String date; to SimpleDateFormat date; or rename the variable date in the line date = new SimpleDateFormat ( "MM/dd/yy*) to something else.

On the contray, if you use System.out.println(date); it's the same as System.out.println(date.toString());

Read the SimpleDateFormat API. And to get even better marks, I suggest that you should use proper naming conviction

Fuck, I'd hate to be convicted of naming. But he is exactly right. Try making your variable names more descriptive. 'date' is a little hard to understand later when you are looking at code. Also try indenting a bit more.

Don't know if you've solved this one, but incase it can help someone else here is a basic solution.

I'm assuming you wanted the date formated MM/dd/yy.. new Date().toString() will give you the date in long format if you want to cut the code down even further i.e. October 20, 2004 10:49PM EST etc....

import javax.swing.*;
import java.util.*;
import java.text.*;



public class OptionPaneTest
{

public static void main(String[] args)
{

SimpleDateFormat dateFormat = new SimpleDateFormat ( "MM/dd/yy" );
String dateToday = dateFormat.format( new Date() );

String name = JOptionPane.showInputDialog(null, "What is your name?" );
JOptionPane.showMessageDialog(null, name + " " + dateToday);

}

}
