Java Convert negative numbers to 0

I am having issues with this code and can't figure out the issue, I know it's a logical error but I can't seem to figure it out, all results end up as 0.

Code:

import java.util.Scanner;

public class ConvertNegative {
   public static void main (String [] args) {
      int userNum = 0;

      if (userNum >= 0)
         System.out.println("Non-negative");
      else
         System.out.println("Negative; converting to 0");
         userNum = 0;
         System.out.format("Final: %d", userNum);
         System.out.println(""); 

      return;
   }
}

I'd appreciate any help, thanks.

If you have multi line conditions / for loops you need to set brackets. Without the brackets your else block would just execute the first statement after it. In your case the System.out.println("Negative; converting to 0");. In any case your variable userName would be set to 0 as the following line wouldn't be part of the else block anymore. More than 1 line = brackets.

public class ConvertNegative {
    public static void main (String [] args) {
        int userNum = 0;

        if (userNum >= 0)
            System.out.println("Non-negative");
        else{
            System.out.println("Negative; converting to 0");
            userNum = 0;
            System.out.format("Final: %d", userNum);
            System.out.println(""); 
        }
        //return; -> There is no need for the return as the main method has no return value.
    }
}
