Help with printing an arrayList. printing the first element twice

[kingkongjaffa]

So basicly guys whats happening is:
1) i'm populating some elements with user input
2)adding these elements to an ArrayList
3)making the arrayList an array with the .toArray() method
4) writing every element of the array to file.

the problem: when I add one element at a time it works just fine

when I add multiple elements it prints the first element twice in the text file then the next element

content after run -add - close - run- add - close (one at a time)

IdA , FirstnameA, SecondnameA
IdB, FirstnameB, secondnameB

content after run- add - add -close (adding multiple)
IdA , FirstnameA, SecondnameA
IdA , FirstnameA, SecondnameA
IdB, FirstnameB, secondnameB

here is my code

System.out.println("Please enter your customer details:");
        System.out.println("Please enter your first name:"); 
        Scanner firstname = new Scanner (System.in);
        fname  = firstname.nextLine();
        System.out.println("please enter your second name");
        Scanner secondname = new Scanner (System.in);
        sname = secondname.nextLine();
        ID = GetNextID();
        BList.add(ID+", "+fname+", "+sname);
        
        WriteCustomerstoFileFromArrayList();

private void WriteCustomerstoFileFromArrayList(){
       Object[] Obj =new Object[1];
       try {
         StartFile(Kudex.CUSTDATA);
         FileWriter outFile = new FileWriter(Kudex.CUSTDATA,true);
         PrintWriter out = new PrintWriter(outFile);
         Obj = BList.toArray();
         System.out.println(Obj.length);
         System.out.println(BList);
       
         
         for (int j=0; j<Obj.length; j++){
           out.println(Obj[j]);
           if (j<Obj.length-1) { out.println();}
       }
       Obj = null;
       out.close();
      }
      catch (IOException e){
         e.printStackTrace();
      }
   }

Please help.

Your code has several printlns:

 System.out.println(Obj.length);
         System.out.println(BList);
       
         
         for (int j=0; j<Obj.length; j++){
           out.println(Obj[j]);

Which one(s) is printing what you posted?

Add some id strings to show what line is printed by which println:

 System.out.println("len=" + Obj.length);
         System.out.println("Blise=" + BList);
       
         
         for (int j=0; j<Obj.length; j++){
           out.println(j + " obj=" +  Obj[j]);

Let me just start off with saying that converting your ArrayList to an array is not necessary at all. Look up enhanced for loops.

You're not showing enough of your code so I can't help past there.

        Scanner firstname = new Scanner (System.in);
        fname  = firstname.nextLine();
        System.out.println("please enter your second name");
        Scanner secondname = new Scanner (System.in);
        sname = secondname.nextLine();

You also don't need multiple Scanners. One will do the job.

How do I set up the enhanced for loop ?

Oh no! Google is broken again.

Object[] Obj =new Object[1];

An array to hold one element is totally pointless.
