Question

Design and implement a program that reads a series of 10 integers from the user and prints their average. Read each input value as a string, and then attempt to convert it to an integer using the Integer.parseInt method. If this process throws a NumberFormatException (meaning that the input is not a valid number), print an appropriate error message and prompt for the number again. Continue reading values until 10 valid integers have been entered.

Answer 1

Code

public class Main
{
   public static void main(String[] args) {
  
   int sum = 0;
   double average;
   int i = 0;   
  
   // Reading 10 integers as strings and adding
   // into sum after conversion from string to int
  
   while(i< 10)
   {
   String value = System.console().readLine();
   try
   {
   sum = sum + Integer.parseInt(value);
   }
   catch(Exception NumberFormatException )
   {
   System.out.println("Please enter the valid number\n");
   continue; // Again asking for number so skipping increment of i
   }
   i++;
   }
  
   average = (double)sum/10;
       System.out.printf("average is: %f", average);
   }
}
