Difference between doGet() and doPost() methods in servlets

doGet() and doPost() are methods in servlets used to handle HTTP GET and POST requests, respectively. The main difference between them lies in the type of request they handle and the parameters they use.

doGet() method is used to handle HTTP GET requests, which are generally used to request data from the server. It takes parameters directly from the URL, and the parameters are visible to users and can be bookmarked. doGet() method is generally used for safe and idempotent operations.

doPost() method, on the other hand, is used to handle HTTP POST requests, which are generally used to submit data to the server. The parameters are sent in the request body, making them not visible in the URL. doPost() method is generally used for operations that modify server data.

In conclusion, the main difference between doGet() and doPost() methods in servlets is the type of request they handle and how they handle parameters. doGet() is used for GET requests and takes parameters from the URL, while doPost() is used for POST requests and takes parameters from the request body.
