Explain JSP cookies and their usage.

JSP Cookies are small pieces of data stored on the client’s browser. They are used to persist information across multiple requests. Cookies can be created, read, and modified using JSP code. Cookies are often used for session tracking, user preferences, and personalization. They can store information such as usernames, user preferences, shopping cart items, etc. Cookies have a limited size and can be set to expire after a specified duration or when the browser is closed.
