Answer 1

import java.text.SimpleDateFormat;
import java.util.Date;

public class Ticket {
   private long number;
   private String category;
   private String holder;
   private Date date;
   private double price;
   private boolean status;
   public Ticket(){
      
   }
   public Ticket(String category,String holder,Date date,double price,boolean status){
       this.category=category;
       this.holder=holder;
       this.date=date;
       this.price=price;
       this.status=status;
   }
   public void setPrice(double price){
       this.price=price;
   }
   public void changePurchaseStatus(boolean status){
       this.status=status;
   }

   public long getNumber() {
       return number;
   }
   public String getCategory() {
       return category;
   }
   public String getHolder() {
       return holder;
   }
   public Date getDate() {
       return date;
   }
   public double getPrice() {
       return price;
   }
   public String toString(){
   SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss");
       return "Number: "+this.number+"\nCategory: "+this.category+"\nHolder: "+this.holder+""
               + "\nDate: "+formatter.format(this.date)+"\nPrice: "+this.price+"\nStatus: "+this.status;
   }
