Question

Task 1 : Write a Java program that prompts for and reads 10 integers from the user into an integer array of size 10, it then: - calculates the sum and average of positive numbers of the array and displays them. [Note: consider 0 as positive] Note: The program must display the message: "There are no positive values" if the array does not contain any positive value.

Answer 1

import java.util.Scanner;
public class Main
{
   public static void main(String[] args)
   {
       Scanner sc = new Scanner(System.in);
       int arr[] = new int[10];
       int i,count=0;
       double sum=0.0;
       System.out.print("Enter 10 integers: \n");
       for(i=0;i<10;i++)
       arr[i] = sc.nextInt();
       for(i=0;i<10;i++)
       {
       if(arr[i]>=0)
       sum=sum+arr[i];
       }
       for(i=0;i<10;i++)
       {
       if(arr[i]==0)
       count++;
       }
       if(sum==0&&count==0)
   System.out.print("There are no positive values.");
   else
   {
   System.out.printf("The sum of positive numbers is %.0f\n",sum);
System.out.println("The average of positive numbers is " +sum/10);
   }
      
   }
}

Enter 10 integers: 1 4 7 8 5 2 3 6 9 10 The sum of positive numbers is 55 The average of positive numbers is 5.5 . .Program finished with exit code o Press ENTER to exit console.

Enter 10 integers: 1 -2 -3 -4 5 6 -7 -8 9 -10 The re are no positive values. . . Program fini shed with exit code 0 Press ENTER to exit console.

Enter 10 integers: 0 1 -2 -3 -4 -5 -6 -7 -8 -9 The sum of positive numbers is 0 The average of positive numbers is 0.0 - ..Program finished with exit code 0 Press ENTER to exit console.
