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.

The behavior of this inspection is controlled by org.intellij.lang.annotations.MagicConstant annotation. Some standard Java library methods are pre-annotated, but you can use this annotation in your code as well.
