 ### Something a bit more complex
 Let's change Main.java and recompile:
 ```java
 public class Main {
-	public static int someInt;
+    public static int someInt;
 
-	public static void main(String[] args) {
-		Main instance = new Main(5);
-		instance.add(3);

 We still expect it to store 10 in `someInt`, but there's more going on here:
