Convert2MethodRef

Reports lambdas that can be replaced with method references. While often it could be a matter of taste, method references are more clear and readable compared to lambdas.

Example:

Runnable r = () -> System.out.println();

After the quick-fix is applied:

Runnable r = System.out::println;

The inspection may suggest method references even if a lambda doesn't call any method, like replacing obj -> obj != null with Objects::nonNull. Use the Settings | Editor | Code Style | Java | Code Generation settings to configure special method references.
