fine to me honestly.
   
   @HyukjinKwon 
   Hi. Code like the following is syntactically correct; but it is bug-prone
   ```java
   if (condition) statements;
   ```
   The problem is sooner or later you or someone else is going to need add a 
line to that if statement.
   ```java
   if (condition) statements; statements;
   ```
   The program has suddenly become buggy. Not everyone does when the buggy 
lines aren’t called out and pointed to as they are here. Even written like 
this, not everyone will see the bug immediately.
