Write a java program to accept an unlimited number of item names and prices, and output them. in addition output the average price if one of the items is named peas (not case sensitive) otherwise output : "no average output". the inputs will be terminated by a sentinel price of - 1. (do not include -1 in the average.)

// main method of the class

public static void main (String[] args) throws java.lang.Exception{

    // scanner object to read input

Scanner scr=new Scanner(System.in);

 // string array

      // read inputs until user enter a price -1

      while(true){

          System.out.print("Enter item " + (i + 1) + " name: ");

          name[i] = scr.next();

          System.out.print("Enter item " + (i + 1) + " price: ");

          price[i] = scr.nextDouble();

          if(price[i] == -1) break;

          if(name[i].equalsIgnoreCase("peas"))

          flag = true;

          sum += price[i];

          i++;

      }

      // print item and their price

      System.out.println("Items and their prices : ");

      for(int y = 0; y < i; y++){

          System.out.println(name[y] + ": " + price[y]);

      }

      // find average

      avg =sum/i;

      if(flag == true){

          System.out.println("Average: " + avg);

      }

      else{

          System.out.println("no average output");

      }

   }catch(Exception ex){

       return;}

}

}

Explanation:

Read name and their price from user until user enters a price equals to -1 of an  item .print all the names and their price .If any name is equal to "peas"  without case sensitive then find the average of all price and print the  average.If their is no name equal to "peas" then print "no average output".

Output:

Enter item 1 name: apple                                                                                                  

Enter item 1 price: 12                                                                                                    

Enter item 2 name: kiwi                                                                                                    

Enter item 2 price: 20                                                                                                    

Enter item 3 name: peas                                                                                                    

Enter item 3 price: 22                                                                                                    

Enter item 4 name: banana                                                                                                  

Enter item 4 price: -1                                                                                                    

Items and their prices :                                                                                                  

apple: 12.0                                                                                                                

kiwi: 20.0                                                                                                                

peas: 22.0
