sorry problems in my alignment and this is the latest code
i am required to design and implement a java application to keep track of the time a yatch is moored at Cardiff Marina then calculate charges due when the owner wishes to sail. it should also ask for users information eg name etc.
Should create a gui to do this and if the user wants an hourly rate then the program should prompt them for the time they enter the marina and the time they leave using a joptionpane. then the data should be entered into a text file

public static void main(String[] args) {
//I have created the gui
new Marina();
}
}
at the moment a gui is displaying but changes have been made since then.
the main things i want to do are
my joption panes show up when i change options on my jcombobox but i want them to show up only when i press the submit button. the command i have wrote to try and do this is in my actionperformed method.
i have created strings called arrival and leave from which i wish to get the text entered into the input joption panes timearrive and timeleave but i am unsure of the command needed to be written to do this
also i have this other class ( i would use a scanner but have been told to use a filweriter and been given example code to help me create the class) which i want to write the strings etc into a document i have created called cdetails.txt but currently has problems. i plan to put this class into my program as shown as above later on when correct
import java.util.*;
import java.io.*;
public class WriteToFile2 {
String name, price, arrival, leave;
int length;
public static void main(String args[]) {
try {
FileWriter fw = new FileWriter ("cdetails.txt");
BufferedWriter out = new BufferedWriter(fw);
// need to get a enter command or something working here out.write("");
out.write(name + " " + length + " " + price + " " + arrival + " " + leave + " ");
}
catch (IOException e) {}
}
}
