What are the differences between @RequestParam and @PathVariable?

Comment

Even though both @RequestParam and @PathVariable annotations are used to extract some data from the URL, there is a key difference between them.

The @RequestParam is used to extract query parameters e.g. anything after "?" in URL while @PathVariable is used to extract the part of the URI itself. 
For example, if the given URL is http://localhost:8080/SpringMVC/books/3232233/?format=json

Then you can access the query parameter "format" using @RequestParam annotation and /books/{id} using @PathVariable, which will give you 3232233.
