Explanation / Answer

import java.util.*;

class Restaurant
{
public static void main (String[] args)
{
  Scanner input = new Scanner(System.in);
  double total = 0;
  int foodItem,mainMenu;
  
  System.out.println("Enter the number of people in the party : ");
  int persons = input.nextInt();
  
  for(int i = 0;i< persons;i++)
  {
  
  System.out.println("Select food item <1.Soups and Salads 2.Appetizers 3.Burgers>");
  
  mainMenu = input.nextInt();
  
  switch(mainMenu)
  {
  case 1:
  System.out.println("Enter the Soups and Salads");
  System.out.println("1.Tomato --------------------$5.00");
  System.out.println("2.Chicken Tortilla ---------$6.50");
  System.out.println("3.Seafood Bisque ---------$9.50");
  System.out.println("4.House ---------------------$6.00");
  System.out.println("5.Caesar ---------------------$8.00");
  foodItem = input.nextInt();
  switch(foodItem)
  {
  case 1: total = total + 5.00;
   break;
  case 2: total = total + 6.50;
   break;
  case 3: total = total + 9.50;
   break;
  case 4: total = total + 6.00;
   break;
  case 5: total = total + 8.00;
   break;
  default: System.out.println("Invalid food item ");
   break;
  }
  case 2:
  System.out.println("Enter the Appetizers:");
  System.out.println("1.Soft Pretzel Sticks -------$5.00");
  System.out.println("2.Spicy Tuna------------------$7.50");
  System.out.println("3.Guacamole ----------------$5.00");
  foodItem = input.nextInt();
  switch(foodItem)
  {
  case 1: total = total + 5.00;
   break;
  case 2: total = total + 7.50;
   break;
  case 3: total = total + 5.00;
   break;
  default: System.out.println("Invalid food item ");
   break;
  }
  case 3:
  System.out.println("Enter the Burgers");
  System.out.println("1.Main Street ----------------$12.00");
  System.out.println("2.Southwest ------------------$14.00");
  System.out.println("3.Original------------------------$11.00");
  System.out.println("4.Steakhouse -----------------$18.00");
  foodItem = input.nextInt();
  switch(foodItem)
  {
  case 1: total = total + 12.00;
   break;
  case 2: total = total + 14.00;
   break;
  case 3: total = total + 11.00;
   break;
  case 4: total = total + 18.00;
   break;
  default: System.out.println("Invalid food item ");
   break;
  }
  
  default: System.out.println("Invalid Menu");
   break;
  }
  }
  total = total +total*0.07;
  System.out.printf("Total after tax for party : $%.2f",total);
  System.out.printf(" Total after tax for each person : $%.2f",total/persons);
}
}
