Write a program that collects any number of non-negative integer inputs and calculates the sum of the values. A negative integer should end the input collection and is not part of the sum.

Output the smallest non-negative value and the sum of the non-negative input values, ending with a newline. Ensure your program output matches the example formatting below and works for a variety of input values.

If the input is:

15

20

0

3

-1

the output is:

Smallest: 0

Sum: 38

Solution

import java.util.Scanner; 

public class LabProgram {
   public static void main(String[] args) {
      Scanner scnr = new Scanner(System.in);      
      /* Type your code here. */
      int smallest = Integer.MAX_VALUE;
      int sum = 0;
      
      while (true){
         int num = scnr.nextInt();
         
         if (num < 0){
            break;
         }
         
         sum += num;
         
         if (num < smallest){
            smallest = num;
         }
      }
      System.out.println("Smallest: " + smallest);
      System.out.println("Sum: " + sum);
   }
}
