Java abstract generic method with wild card implemented with concrete type

Is it possible in java to define an abstract method with wildcard but in the implementation use a concrete type

eg:

Define the abstract method in an abstract class like this

public abstract class AbstractAuthorizer {
    abstract protected <T extends User> void authorize( T user );
}

Implement the abstract method like this, where CorporateUser extends User :

public class CorporateAuthorizer extends AbstractAuthorizer {

    @Override
    protected <CorporateUser> void authorize(CorporateUser user){
    }
}
