In this project you will create a Java application that inherits from a Car class in Java and use aggregation and composition in a class that uses one to many Car objects. Code re-use allows the developer to use tried and tested code, which results in more reliable code and saves in development time as well. In Object-Oriented Programming in a language such as Java, code re-use can be accomplished in two distinctive ways. One way is to inherit from an existing class by extending its existing functionality. A Car class for example can be extended by a Used Car class by adding a parameter to indicate the number of miles on it. Another common way to re-use code is through aggregation and composition. In aggregation, the class is made up of other existing classes that may exist independent of the parent class. Note: This course works best for learners who are based in the North America region. We’re currently working on providing the same experience in other regions.
