What is dependency's in java ?

In Java, a dependency refers to the relationship between two components of an application where one component, called the "dependent component", relies on another component, called the "dependency", to perform its task.

Dependencies in Java can take various forms, such as a library, a module, a framework, or an external system. For example, if an application needs to perform a database operation, it may have a dependency on a database driver library.

Managing dependencies is an important aspect of Java development, as it affects the performance, stability, and maintainability of the application. One popular tool used for managing Java dependencies is Apache Maven, which is a build automation tool that manages the project's dependencies and generates the required artifacts, such as JAR files and WAR files.

Dependency injection, which I mentioned in my previous answer, is also a technique used in Java to manage dependencies between different components of an application. By using a dependency injection framework, Java developers can manage dependencies more easily and effectively, while keeping the application modular and testable.
