Java - If Else Logic

I'm having a difficult time understanding why the second string does not print. Even if I comment out the "third string" print line, there is no output.

public class SecretMessage {
       public static void main (String [] args) {
            int aValue=4;
            if (aValue > 0){
                if (aValue == 0)
                System.out.print("first string   ");
        }
        else 
        System.out.println("second string   ");
        System.out.println("third string   ");
        }
    }

Why doesn't the "second string" print? I thought that anything under the else block would be executed, so both second and third string should be printed.

Thanks in advance!
