'Dead code' as it name suggests is a piece of code which is dead or has got no chance of it being executed. In other words dead code is a type of code which is unreachable. I will provide an example which will helps in understanding more about dead code. Consider a piece of code in Java.

Hi Everyone, in this post, I will be discussing about how to add another project as a dependency in maven. Maven is a build automation tool primarily used for java projects. Currently, maven is the most common build tool used in the software market. Please check the wiki page for maven to know more topics.

To add a project as a dependency in Maven, the project is added as a dependency to pom.xml of the project which refers the latter project. pom.xml is the xml representation of maven project. It stands for project object model. Click here to read more about pom.xml. The structure of the first project is as follows: The class file MavenProject.java is as follows: package  com.techjourney.maven; public   class  MavenProjec...
