What Is Javax Inject

Package javax. inject. This package specifies a means for obtaining objects in such a way as to maximize reusability, testability and maintainability compared to traditional approaches such as constructors, factories, and service locators

What is @inject used for?

Injectable constructors are annotated with @Inject and accept zero or more dependencies as arguments. @Inject can apply to at most one constructor per class. @Inject is optional for public, no-argument constructors when no other constructors are present. This enables injectors to invoke default constructors.

What does inject mean Java?

In Java, before we can use methods of other classes, we first need to create the object of that class (i.e. class A needs to create an instance of class B). So, transferring the task of creating the object to someone else and directly using the dependency is called dependency injection.
