Question

4. Gathering Positivity

by CodeChum Admin

I always want to look at the positive side of things, so I decide to seriously look at positive numbers, too!

Will you code along with me?

Instructions:

1. Using the do…while() loop, continuously scan for integers, but add up only all the positive integers and store the total in one variable.
2. The loop shall only be terminated when the inputted integer is zero. Afterwards, print out the total of all inputted positive integers.

Instructions

1. Using the do…while() loop, continuously scan for random integers, but add up only all the positive integers and store the total in one variable.
2. The loop shall only be terminated when the inputted integer is zero. Afterwards, print out the total of all inputted positive integers.

Input

Multiple lines containing an integer on each.

package com.company;
import java.util.ArrayList;
import java.util.*;
class Main{
    public static void main(String arg[])
    {
        //propmt the user to enter a positive odd integer
        Scanner sc = new Scanner(System.in);
        //declare a variable to store the sum of inputted integers and initilaize it to 0
        int input_integer_sum = 0;
        System.out.println("\nEnter integers, to stop entering enter integer 0\n");
        int condition = 1;
        do {
            System.out.print("Enter an integer: ");
            int my_integer = sc.nextInt();
            if(my_integer==0)
            {
                condition = 0;
            }
            else
            {
                //sum the positive integers only
                if(my_integer>0)
                {
                    input_integer_sum = input_integer_sum + my_integer;
                }

            }

        }while (condition==1);
        //print the output
        System.out.println("\nOUTPUT:\n");
        System.out.println("The sum of all the inputted positive integers = "+input_integer_sum);

    }
