How do i open JFrame in the same active window

[Jkiller295]

like the code above, i successfully read the whole table of Clients and Addresses. Now i want to use the Street name only for the combobox, i tried to use line.split(); but this gave me another string of array. How can i separate the street name only, to put in the combobox

[PhHein]

Huh? You haven't created an Address class yet. And I don't see where you fill the List of addresses. You're like three steps further than you should be.

[Jkiller295]

oh snap. i posted the wrong code and didnt recheck just now :P

import java.io.*;
import java.util.LinkedList;
public class Address
{
	LinkedList addressList = new LinkedList();
	
	Address()
	{
		inputAdd();
	}
	public void inputAdd()
	{
		try
		{
			BufferedReader br = new BufferedReader(new FileReader("Addresses.csv"));
			while(true)
			{
				String line = br.readLine();
				if(line == null)break;
				addressList.add(line);
				System.out.println(line); // display the address
			}
			System.out.println();
			br.close();
		}
		catch(IOException io)
		{
			System.out.println(io.getMessage());
		}
	
	}
	public Object getAddress(int index)
	{
		return addressList.get(index-1); // the list index starts with 0
	}
	public static void main(String []args)
	{
		Address a=new Address();
		System.out.println(a.getAddress(49)); //testing to get a specific address
		String s = (String)a.getAddress(0);
		String []sa = s.split(",");
		System.out.println(sa[3]+" - "+sa[2]);
	}
}

the client class should be the same. at this line
System.out.println(sa[3]+" - "+sa[2]);
this is what i want to be displayed in the comboBox, and comboBox only takes 1 String [] as argument right ? So, there are 50 addresses ? what's the correct way ? :confused:

[PhHein]

Again, you should not add the line to the List, but 50 instances of a custom class Address. This class encapsulates the Client ID, road, post code etc, it does not do any file reading. You need to fill a CombBoxModel with those Address instances. And I'd use an ArrayList instead of a LinkedList.

i dont understand this part, so where do i actually do the file reading ?? im really confused now :confused:

[PhHein]

In some other class, or your main process class.

[Jkiller295]

just to clarify, are u saying that the client & address classes are just to store data that is read from the static main method ?? then passing them around to other classes ?

[PhHein]

Yes, they are only used to store the data. No, your main method should never contain more than a handful lines of code.

oki doki, thanks a lot. let me try. 1st time learn object oriented :(

Hi, I'm back :D
The attachment is my current project. Everything seems to work fine. Now I just need a way to export the data to a text file.
The format of output is

L.K. Simons ABN 20-345-459 // my company name
Collection Service Invoice //title
Collection Date: 21-05-2010 //current date
Client: Megadodo Publications // owner of the address chosen from comboBox

Service Address:
12,Bowman St, Seven Hills, 2147 // comboBox

Collection Details:
Recycling : blah blah blah // anything from the NewCollection class

Net $xx,xx GST $xx,xx Total $xx,xx //also calculated in NewCollection class

That's all :D

[PhHein]

See reply #2, third link, IO tutorial. That covers all you need.

[Jkiller295]

no no.. i know how to write to a file using BufferedWriter, but not in the format mentioned above, specifically with all the data. Do i have to make another class and then get information from 1 of the class I currently have or something ?

[PhHein]

Well you have all the information needed somewhere. Gather all the bits and pieces and pass them to an output class or method and write them to file.

[Jkiller295]

wa. informations are scattered all over the place. im doomed

[chyrl]

This thread is a String manipulation problem.
The solution are said to you.

Try reading the BufferedWriter API. This would solve on how you could manipulate the file. If I am not mistaken, using the append method would append a string to the file.

You should understand further how the data in the file are used and placed.

You're making progress in the last posts.

oki doki. i guess have to read all the I/O stuff again :D
thanks anw
