Use curly braces effectively

Guidewire recommends the following best practices for effective use of curly braces:

• Surround every logical block, even single-statement blocks, with curly braces ({}).
• Put the opening curly braces ({) on the same line that starts the block.
• Put the closing curly brace (}) on the line after the last statement in the block, aligned with the starting column of the block.

  if(premium <= 1000) {                   // Put opening curly brace on line that starts the block.
    print("The premium is " + premium)    // Surround even single-line blocks with curly braces.
  }                                       // Put closing curly brace on line after last statement.
