"Java" and "Java full-stack" refer to different aspects of software development:

Java:

Java is a popular, versatile, and widely-used programming language. It is known for its portability, as Java code can run on various platforms without modification.
Java is used for a wide range of applications, including web development, mobile app development (using Android), desktop applications, server-side development, and more.
In web development, Java is commonly used on the back end to build server-side logic and manage databases. Java-based web frameworks like Spring and Java EE (Enterprise Edition) facilitate the development of web applications.
Learning Java involves mastering the language's syntax, libraries, and object-oriented programming principles, which can be applied in various domains.
Java Full-Stack Development:

Java full-stack development specifically refers to the role of a developer who is proficient in both front-end and back-end development using Java technologies.
A Java full-stack developer has expertise in:
Front-end technologies like HTML, CSS, JavaScript, and front-end frameworks (e.g., React, Angular, or Vue.js).
Back-end development using Java, often with frameworks like Spring Boot or Java EE.
Database management and interaction, which may include SQL databases (e.g., MySQL, PostgreSQL) and NoSQL databases (e.g., MongoDB).
Web application deployment and server management.
Building end-to-end web applications, from designing user interfaces to implementing server-side logic and managing databases.
In summary, "Java" is the programming language itself, while "Java full-stack" refers to the skill set and role of a developer who can work on both the front-end and back-end aspects of web development using Java. Java full-stack developers are responsible for creating complete web applications, while Java as a language can be used in various software development contexts beyond web development.
