Question

In Java please:Re-type the code and fix any errors. The code should convert non-positive numbers to 1. if (userNum > 0) System.out.println("Positive."); else System.out.println("Non-positive, converting to 1."); userNum = 1; System.out.println("Final: " + userNum);

Answer 1

Answer:

import java.util.Scanner;

public class Solution {

   public static void main(String args[]) {

       Scanner scan = new Scanner(System.in);

       int userNum = scan.nextInt();

       if (userNum > 0) {

           System.out.println("Positive.");

           

       } else {

           System.out.println("Non-positive, converting to 1.");

           userNum = 1;

           System.out.println("Final: " + userNum);

           

       }

   }

}

Explanation:

There was no error found when the code was run. The code segment was just added to a main method and it runs successfully.

Based on the full code above;

The first line import the Scanner class which allow the program to receive user input. Then the class was defined as Solution. Then the main method was defined. Inside the main method, we created a scanner object scan which receive the input via keyboard. The user input is assigned to the variable userNum. Then the if-conditional statement is executed; if userNum is greater than 0, "Positive" is output. Else userNum is converted to 1 and outputted to the screen.
