Magic constant
Reports expressions that can be replaced with "magic" constants.
Example 1:
// Bare literal "2" is used, warning:
Font font = new Font("Arial", 2)
Example 2:
// Predefined constant is used, good:
Font font = new Font("Arial", Font.ITALIC)
When possible, the quick-fix inserts an appropriate predefined constant.
