Use whitespace effectively

Guidewire recommends the following best practices for effective use of whitespace:

• Add spaces around operators.

  premium = Rate + (minLimit - reductionFactor)  // proper form

  premium=Rate+(minLimit-reductionFactor)        // improper form

• Add no spaces between parentheses and operands.

  ((a + b) / (c - d)) // proper form

  ( ( a + b ) / ( c - d ) )  // improper form

• Indent logical blocks of code by two spaces only.
• Add a blank line after code blocks.
• Add two blank lines after methods, even the last method in a class.
