Unnecessary 'default' for enum 'switch' statement

Warning
New
Last modified: 03 December 2024

Reports enum switch statements or expression with default branches which can never be taken, because all possible values are covered by a case branch.

Such elements are redundant, especially for switch expressions, because they don't compile when all enum constants are not covered by a case branch.

The language level needs to be configured to 14 to report switch expressions.

The provided quick-fix removes default branches.

Example:

After the quick-fix is applied:

Use the Only report switch expressions option to report only redundant default branches in switch expressions.
