Java Full Stack development refers to the practice of building both the front-end and back-end of web applications using Java technologies. This typically involves working with Java frameworks like Spring or Java EE for the server-side logic and integrating them with front-end technologies such as HTML, CSS, JavaScript, and frameworks like React or Angular. Full Stack developers are skilled in database management, often utilizing SQL databases like MySQL or PostgreSQL, as well as NoSQL databases like MongoDB. This versatility allows them to create comprehensive applications that encompass the entire development lifecycle, from user interface design to server-side implementation.
