Re-type the code and fix any errors. the code should convert non-positive numbers to 1.

Question

Problem :

I am facing issues with following Java  code and unable to figure out the cause behind the issue, I guess it is some logical error but I am unable to figure it out, my all results are ending up as 0.

Please find below the Java Code:

import java.util.Scanner;

public class MyConvertNegative {

   public static void main (String [] args) {

      int myUserNum = 0;

      if (myUserNum >= 0)

         System.out.println("Poitive");

      else

         System.out.println("Negative; Converting To 0");

         myUserNum = 0;

         System.out.format("Final Result: %d", myUserNum);

         System.out.println(""); 

      return;

   }

}

Please let me know how can I fix this issue?

In your code I can see that you have the multi line conditions so you need to set the brackets. Without them your else block will just execute the first line of the code after it. So in your case the line executed is  System.out.println("Negative; Converting To 0");. So in that case your variable myUserNum would be set to 0 as the next line will not be the part of the else block anymore. So you need to follow the More than 1 line = brackets.

public class MyConvertNegative {

    public static void main (String [] args) {

        int myUserNum = 0;

        if (myUserNum >= 0)

            System.out.println("Poitive");

        else{

            System.out.println("Negative; Converting To 0");

            myUserNum = 0;

            System.out.format("Final Result: %d", myUserNum);

            System.out.println(""); 

        }

        //return; -> No need for the return as your main function is not returning any value.

    }

}
