Dependency Injection is a design pattern that allows us to remove the hard-coded dependencies and make our application loosely coupled, extendable and maintainable. We can implement dependency injection to move the dependency resolution from compile-time to runtime.
- This code is only used to see at runtime how the Dependency Injection mechanism works using basic classes and methods.
- Well-crafted and crafted code can be implemented into a future library and framework that you want to create from scratch for learning purposes.
To run the Java project without using Maven or any other build tool, follow these steps:
-
Compile the Java source files:
-
Open a terminal and navigate to the root directory of the project (
java-dependency-injection). -
Use the
javaccommand to compile the source files and specify the output directory asbin:javac -d bin src/**/*.java
-
-
Run the compiled Java program:
-
After compiling the source files, you can run the
Appclass using thejavacommand:java -cp bin App
-
