What method of dependency injection is considered most recommended in modern programming practices?

The most recommended method of dependency injection in modern practices is constructor injection.

Advantages:

• Ensures immutability of dependencies after object creation.
• Allows easy testing of the class by substituting mocks or stubs.
• Clearly shows what the class depends on.

Example in Java:

public class Service {
    private final Repository repository;

    public Service(Repository repository) {
        this.repository = repository;
    }

    public void doWork() {
        repository.save();
    }
}

Here, Repository is passed through the constructor, which simplifies dependency management.
