can‘t resolve the @param annotation in java program

How can I fix it in Idea.Thx.

error

>Solution :

Try to move comment after sign of class and before sign of function
Your class (raw sign) don’t have any params, so they can’t be resolved
But function’s params are ‘invisible’ for comments outside class.
