Difference between Query and Path

Difference between @Query and @Path on Retrofit2 Android :

// @Query

=> Example API : https://jsonplaceholder.typicode.com/posts?userId=1&_sort=id&_order=desc

    @GET("posts")
    Call<List<Post>> getPosts(
            @Query("userId") Integer userId,
            @Query("_sort") String sort,
            @Query("_order") String order
    );

// @Path

=> Example API : https://jsonplaceholder.typicode.com/posts/2/comments

    @GET("post/{id}/comments")
    Call<List<Comment>> getComments(@Path("id") int postId);
