Summary
When developing applications, processing data is one of the most fundamental tasks. In this lesson, you learned how to read and parse data from files so that you're able to process them as part of your application. You also learned how to compare objects so that you can sort them in different ways.
As part of processing data, you learned how to store data using basic and advanced data structures. Knowing how to efficiently process data is very important so that you avoid resource contention scenarios such as running out of memory, or requiring too much processing or time to execute the task at hand. A big part of processing data efficiently is about picking the right data structures and algorithms for the right problems. All the new tools that you have added to your belt will help you make the correct decisions when building your Java applications.
In the next lesson, we will have a look at some advanced data structures.
