text file

Hello can I modify the program below so that all the numerical data is stored in an external text file,that is the data contained in the array list.Thank you!

mport java.util.*; import java.text.*; import java.util.Scanner; class HardwareItems { String code; String description; double price,total; double vat=0.2; // variable declaration int weight,quantity,shipping, cost; // variable declaration

HardwareItems(String code,String description,double price){
    this.code=code;
    this.description=description;
    this.price=price;
}
public String getCode(){
    return code;
}
public String getDescription(){
    return description;
}
public double getPrice(){
    return price;
}

public static void main(String []args){
    ArrayList<HardwareItems> list=new ArrayList<HardwareItems>();
    list.add(new HardwareItems("K16","Wood screws,brass,20mm,50 grams",7.75));
    list.add(new HardwareItems("D24","Wood glue,clear,1 liter,350 grams",5.50));
    list.add(new HardwareItems("M93","Sandpaper,fine grade,50 grams",10.25));
    list.add(new HardwareItems("M94","Sandpaper,fine grade,60 grams",14.75));
    list.add(new HardwareItems("B21","Claw Hammer,1500 grams",13.50));
    list.add(new HardwareItems("B35","Garden Shovel,2200 grams",15.00));
    list.add(new HardwareItems("A10","Garden Hose,2100 grams",10.25));
    list.add(new HardwareItems("A45","Hand Saw,1000 grams",12.75));
    list.add(new HardwareItems("C51","Garden Fork,2400 grams",14.50));
    DecimalFormat df=new DecimalFormat("$ ##.##");

    System.out.println("Hardware Items");
    System.out.println();
    System.out.println("Code "+"   Description "+"            Unit Price ");
    for(HardwareItems e : list){
            System.out.println(e.getCode()+"\t"+e.getDescription()+"\t"+df.format(e.getPrice()));
            }


      Scanner in=new Scanner (System .in);
    System.out.println("place your order!");
    System.out.print("NAME:");
    String l=in.nextLine();
    System.out.print("ADDRESS-1:");
    String m=in.nextLine();
    System.out.print("ADDRESS-2:");
    String n=in.nextLine();
    System.out.print("ADDRESS-3:");
    String o=in.nextLine();
    System.out.print("POST CODE:");
    String p=in.nextLine();

    Scanner input=new Scanner(System.in);
    System.out.print("Code:" );
        String code=input.next();
        System.out.print("Quantity: ");
        int quantity=input.nextInt();
        String check="";
          while(!check.equals("no")){
        System.out.print("Is there another Customer order?(yes/No) :");
         check=input.next();
        if(check.equals("yes")){
         System.out.print("Code:" );
            code=input.next();
         System.out.print("Quantity: ");
            quantity=input.nextInt();
        }
        else{
            break;
            }
           }
        }
