We do this to make the code more readable. It is not part of the Java syntax however and the code will still compile if we don't bother to do this.

As our code gets more complicated, indenting along with comments, help to keep the meaning and structure of our code clear. I mention this now because when we start to learn the syntax for making decisions in Java, indenting becomes especially useful and...
