What are Java doGet () and doPost () methods?

The doGet() method is used to fetch the information from the server, whereas the doPost() is used to send or transfer the information to the server.

doGet() method is labelled by the servlet service method, which is used to handle the HTTP GET request. In case of overriding this method, ensure to read the requested data and then write the response headers. Once you get the output stream object or the response's writer, only then write the response data.

doPost() method is labelled by the servlet service method to manage the POST request from the client. This method sends the files to the server and works similarly to the FTP operations from the client to the server.
