In this chapter, we took a look at the super and this keywords. We also looked at examples to explain where we can use these keywords to overcome certain obstacles. We learned about exceptions, and implemented them in various instances where the code failed due to an error. We also learned about the finally block.

In the next chapter, we will dive deep into the collections framework, which consists of interfaces and classes. We will also take a look at the three major collections: List, Set and Map.
