The Difference Between doGet() and doPost() in a Servlet

In a Servlet, the main difference between doGet() and doPost() methods lies in how they handle HTTP requests.

The doGet() method is used to retrieve information from the server, and it is recommended for requests that do not change server data. This method is ideal for displaying data and does not involve modifying server-side data.

On the other hand, the doPost() method is used to send and update information on the server. This method should be used when the request could potentially change server-side data, such as when submitting a form or sending user inputs.

It is important to note that the choice between doGet() and doPost() should be based on the nature of the request and the desired outcome of the server interaction.
