Explore how to organise, manipulate, and store data in Java. Master dynamic structures like Lists and Maps, implement custom sorting logic, and persist application data to files using modern I/O techniques for robust and scalable software design.
In the early weeks of learning Java, arrays appear to be the ideal solution for storing data. They are simple, fast, and easy to declare. However, as our applications grow, the limitations of arrays become increasingly apparent. What happens when you...
In the previous blog of this series, we learned how to store and organise data using flexible structures like Lists and Maps. We can now easily create a dynamic list of students or look them up instantly by their ID. But storing data is rarely enough...
In the previous two blogs of this series, we mastered the art of organising data in memory using Collections and Sorting. We can now create dynamic lists of items, look them up instantly via maps, and sort them by any criteria we choose. But every pr...
