@PathParam:

@PathParam is used to extract values from the path or URI of a RESTful web service.
It is typically used to capture values from the URL template or the path of the request.
Path parameters are included in the URL path itself, typically enclosed in curly braces {} within the @RequestMapping or @GetMapping annotations.
For example, if you have a URL like /api/users/{userId}, you can use @PathVariable to extract the userId from the path.

@QueryParam:

@QueryParam is used to extract values from the query parameters of a request.
Query parameters are included in the URL after a question mark ? and are typically in the form of key-value pairs.
They are useful for filtering, sorting, or providing additional information to the server.
For example, in the URL /api/products?category=electronics&brand=sony, you can use @RequestParam to extract the category and brand query parameters.

In summary, @PathParam is used to extract values from the path of the URL, while @QueryParam is used to extract values from the query parameters of the URL. The choice between them depends on your API design and the way you want to structure your endpoints and request parameters.
