   double amount;
   public BooksExpenses(String p,int i,int b,double a){
       person = p;
       id = i;
       books = b;
       amount = a;

   void set_person(String p){
       person = p;

   void set_id(int i){
       id = i;

   void set_books(int b){
       books = b;
   }
   void set_amount(double a){
       amount = a;

   int get_books(){
       return books;
   }
   int get_amount(){
       return amount;
   }

   void BuymoreBooks(){
       Scanner sc = new Scanner(System.in);
       System.out.print("Do you want to buy more books (enter Y for yes otherwise N) ");
       String s = sc.nextLine();
       if (s.charAt(0) == 'y' || s.charAt(0) == 'Y'){
           System.out.print("How many you want to by : ");
           int n = Integer.parseInt(sc.nextLine());
           books += n;
           amount += 200*n;
       }
   }

   void sellBooks(){
       Scanner sc = new Scanner(System.in);
       System.out.print("Do you want to sell any books (enter Y for yes otherwise N) ");
       String s = sc.nextLine();
       if (s.charAt(0) == 'y' || s.charAt(0) == 'Y'){
           System.out.print("How many you want to sell : ");
           int n = Integer.parseInt(sc.nextLine());
           if (n <= books){  
               books -= n;
               amount -= 200*n;
           }
           else{
               System.out.println("Yo do not have that much of books");
