FileWrtier, ny linie

Hejsa. Jeg har et lille problem med skrivning til en fil.

Når den skiver til en fil, laver den ikke ny linie, men bare et firkant tegn.

Min kode:
        FileWriter item = new FileWriter("c:\\items.txt",true);
        BufferedWriter items = new BufferedWriter(item);
       
        String title = "Register";
        String itemNo = request.getParameter( "Itemno" );
        String itemName = request.getParameter( "Itemname" );
        String itemUnit = request.getParameter( "unit" );
        String itemPrice = request.getParameter( "Price per unit" );
        String itemType = request.getParameter( "ItemCategory" );
       
       
        items.write("Itemno: " + itemNo + "\n");
        items.write("Itemname: " + itemName+ "\n");
        items.write("Unit: " + itemUnit  + "\n");
        items.write("Price per unit: " + itemPrice + "\n");
        items.write("ItemCategory: " + itemType + "\n");
       
        items.close();
