Lessons Learned
I learned about inheritance in Java and the relationship between parent and child classes. The parent class’s methods can be overridden by its children to produce a different implementation of that method. In this case it was the procedure to calculate the area or volume of a shape that differed from shape to shape. I also learned about overloaded constructors as not every shape had the same number of input parameters. Some required 2 or 3 parameters in their construction. This project further solidified my java knowledge and cemented these concepts in my head.
