While Loops - Error

[ZombieGurL]

Hi,
I have been asked to write a program for one of my 1st year modules. im new to programming. Given below is the question. I have answered it partly and there are some errors and its incomplete too. it would be really great if someone could help me to complete it.

To pass this exercise you must demonstrate that you are able to
Write a program using WHILE loop constructs.
Write a program that is well indented.
Write a program that contains helpful comments.
Write a program that uses variable names that give an indication of their use.
Earliest Dates Write a program that repeatedly asks for the user to type in the name of a current film and then asks for its release date. It should stop when the special code QUIT is entered, and name the film that was released first. If several films were released in the earliest year the program should return the name of the last film entered.

Name a film? INCEPTION
What year was INCEPTION released? 2010

Name a film? TANGLED
What year was TANGLED made? 2011

Name a film? DIRTY DANCING
What year was DIRTY DANCING made? 1987

Name a film? PHILADELPHIA
What year was PHILADELPHIA made? 1993

Name a film? QUIT

The earliest film was Dirty Dancing released in 1987

This is the code that Iv written so far. I have no idea how to do beyond this.

mport javax.swing.*; // import the swing library for I/O

class films
{
public static void main (String[] param)
{

movies();
System.exit(0);

} // END main


public static void movies()
{
String again = "";
String film;
int currentyear=2011;
String year = "";
String textinput1;
int oldest year=9999;

String textinput3;

while (!(again.equals("QUIT")))
{

film = JOptionPane.showInputDialog("Name a film");

textinput1 = JOptionPane.showInputDialog
("What year was" +film+ "released");
year = Integer.parseInt(textinput1);


again = JOptionPane.showInputDialog("Name a film");
}

System.out.println("The earliest film was");

if (current year < year){ // i cant seem to sort out the rest of the if statement

return;


} // END

} // END class

Thanks in advance

We don't read minds. Do you think that posting the exact error message might be helpful?

[ZombieGurL]

the program is incomplete i just need your help to complete it

[Junky]

Well that is not going to happen. Try Rent-a-coder.

On the other hand if you actually want help instead of committing academic dishonesty then you should ask a sepcific question about a specific problem you are having and I would be more than happy to provide a specific answer.

You shouldn't have two variables with the same name.

The variable year inside the while loop, if it even allows it to be valid at all, which I'm not sure about, as it has the same name as the String variable year, goes out of scope once the loop ends anyway and so you're comparing Strings and integers.

Actually, on a second inspection, you've assigned a String variable an int value. That'll cause an error.

Usually you should initialize variables like film and textinput1 before going into the loop.

Are you trying to show a dialog box?

JOptionPane.showMessageDialog(null, "The earliest film was");

Are you trying to show some error message to report if the movie year isn't possible? (Also try also having a block to check to see if it's like before 1900 as they didn't have anything except maybe, and a very small maybe, slides or something, back then.)

JOptionPane.showMessageDialog(null, "Year " + year + " hasn't even happened yet!!!!!", "Invalid year", JOptionPane.ERROR_MESSAGE);

Are you trying to figure out a plain message box?

JOptionPane.showMessageDialog(null, "The earliest film was");

You are kind of vague on the error but I'm thinking it's related to the two variables with the same name.
