Data Type Conversions in Java

Unlike PHP or JavaScript, Java is a strongly typed programming language. It essentially means that each variable must be declared with a pre-defined data type that can not be changed afterwards. There are two data types in Java:

  • Primitive data types - int, double, float, byte, long, boolean, etc.
  • Reference data types - Integer, Double, Float, Date, String, Object, etc.

In this tutorial, we will focus on type conversion for primitive data types.

How to Use Cookies in Spring Boot

An HTTP Cookie (also known as a web cookie or browser cookie) is a small piece of information stored by the server in the user's browser. The server sets the cookies while returning the response for a request made by the browser. The browser stores the cookies and sends them back with the next request to the same server. Cookies are generally used for session management, user-tracking, and to store user preferences.

Cookies help server remember the client across multiple requests. Without cookies, the server would treat every request as a new client.
