io question

[patrick tang]

hi all, i've a question about io

import java.io.*;
class Mall
{
protected static File mall;
public Mall() throws IOException
{
mall = new File("mall");
mall.mkdirs();
}
}
public class StoreTest extends Mall
{
private File storename,
     manager,
             catalogue,
     order;
privatestatic File findstore;

public  StoreTest(String sn) throws IOException
{
storename = new File("mall", sn);
storename.mkdirs();
manager = new File(storename, "manager");
manager.createNewFile();
catalogue = new File(storename, "catalogue");
catalogue.createNewFile();
order = new File(storename, "order");
order.createNewFile();
        }
public  static File findStore(String s)
{
File files[] = mall.listFiles();
for(int i=0; i < files.length;i++)
{
String s1 = new String("mall"+File.separator+s);
System.out.println(s1);
String s2 = files[i].getName();
System.out.println(files[i]);
if (s1.equals(s2))
{
System.out.println("yes");
findstore = files[i];
}
System.out.println("no");
}
return findstore;
}

public static void main(String[] args) throws IOException
{
StoreTest store1 = new StoreTest("store1");
StoreTest store2 = new StoreTest("store2");
StoreTest.findStore("store2");
}
}

i'm trying to use method findStore(string s) to find the store with the same name as s. the idea is in gui,i can select the store from a combobox and read the catalogue of that particular store to a textarea. the problem is that findStore doesnt work. you may see that there're two stores in the mall. when i try to find store2, it wont return yes and that store file. i've spent a lot of time on it but still dont get it.
can anyone pls help me out...again? thanks in advance

Are these stored in two different files?
Mall.java and StoreTest.java?

Hi Patrick,
Looking at the Java API, getName() returns the very last element of the file's path - so for a file C:\mall\store2, it would return "store2". That's what s2 is set to. But you're setting s1 to "mall\store2" ("mall" + File.separator + s) - so s1 and s2 won't be equal and you won't find the store. I think you should probably just compare s2 to s.
Hope this helps,
Kathy
