Question

(JAVA)
Implementing a Program Design a program that prompts the user for twenty numbers. If the number is positive, then add the number to the current sum. If the number is negative, then subtract the sum by one. Implement just the main method. Assume that all libraries are imported, and class has been declared.

Answer 1

Java code:

import java.util.Scanner;
public class Main{
  
//required main function(from line 4 to 25) sample class is written only to print the output
   public static void main(String[] args){
       Scanner input=new Scanner(System.in);
       //initializing number
       int num,sum=0;
       //asking for num
       for(int i=0;i<20;i++){
       //asking for number
       System.out.print("Enter the number: ");
       //accepting it
       num=input.nextInt();
       //checking if the number is positive
       if(num>=0)
       //adding the number to sum
       sum+=num;
       else
       //decrementing sum by 1
       sum--;
       }
       //printing sum
       System.out.println("Sum="+sum);
   }

  
}
