HackerRank Java Factory Pattern problem solution

In this HackerRank Java Factory Pattern problem in java programming, you are given an interface Food. There are two classes Pizza and Cake which implement the Food interface, and they both contain a method getType().

The main function in the Main class creates an instance of the FoodFactory class. The FoodFactory class contains a method getFood(String) that returns a new instance of Pizza or Cake according to its parameter. Please complete the FoodFactory class.

import java.util.*;
import java.security.*;
interface Food {
   public String getType();
  }
  class Pizza implements Food {
   public String getType() {
   return "Someone ordered a Fast Food!";
   }
  }

  class Cake implements Food {

   public String getType() {
   return "Someone ordered a Dessert!";
   }
  }
  class FoodFactory {
    public Food getFood(String order) {

switch (order){
     case "pizza": return new Pizza();
     case "cake" : return new Cake();
     default : return null;
}

}//End of getFood method

  }//End of factory class

  public class Solution {

   public static void main(String args[]){
      Do_Not_Terminate.forbidExit();

    try{

      Scanner sc=new Scanner(System.in);
      //creating the factory
      FoodFactory foodFactory = new FoodFactory();
  
      //factory instantiates an object
      Food food = foodFactory.getFood(sc.nextLine());
  
      
      System.out.println("The factory returned "+food.getClass());
      System.out.println(food.getType());
    }
    catch (Do_Not_Terminate.ExitTrappedException e) {
      System.out.println("Unsuccessful Termination!!");
    }
   }

  }
  class Do_Not_Terminate {
     
      public static class ExitTrappedException extends SecurityException {

      private static final long serialVersionUID = 1L;
      }
   
      public static void forbidExit() {
          final SecurityManager securityManager = new SecurityManager() {
              @Override
              public void checkPermission(Permission permission) {
                  if (permission.getName().contains("exitVM")) {
                      throw new ExitTrappedException();
                  }
              }
          };
          System.setSecurityManager(securityManager);
      }
  }
