I'm trying to learn java serialization, and I tried a code just like the one on this page
So I created my own code with my own objects.
The problem is that I specified to save the data into a file named "Inv.dat".
I have never actually seen that file being created, but, since I'm able to print the objects I added on the Write class from the Read class, my code works.

Code:

public class Write{
       public Write(){
         
         String filename = "Inv.dat";      
         inventory.Inventory storeA = new inventory.Inventory ();
......

         try{
            FileOutputStream fos = new FileOutputStream(filename);
            ObjectOutputStream out = new ObjectOutputStream(fos);
            out.writeObject(storeA);
            out.close();
            
         }// end try
......

Code:

public class Read{
       public static void main(String[] args){
         
         String filename = "Inv.dat";      
         FileInputStream fis = null;
         ObjectInputStream ois = null;
         inventory.Inventory storeA = null;
         
         try{
             fis = new FileInputStream(filename);
             ois = new ObjectInputStream(fis);
             storeA = (inventory.Inventory)ois.readObject();
         }//end try
.....
System.out.println(storeA);
.....

Does this mean Inv.dat has been created somewhere where I don't see it?
If so, where is Inv.dat being created or saved?

Ah, never mind, I found it, now the question is why did it save it there? I've got the following directories:

MyDocuments > Java > CS211 > lab9 > persist
presist contains the Read/Write classes, and lab9 contains 2 other classes that create the objects. Inv.dat was created on the CS211 directory.
Thanks
