How do you import classes and use try blocks in Java?

In the third part of this Java tutorial series, we delve into importing classes to enhance Java’s capabilities. Building on the basics covered earlier, such as variables, objects, and loops, this segment explores object-oriented programming and modular programming. The modular approach allows for code reuse, which is beneficial for large projects and teams. By importing additional classes, such as the Scanner class, you can extend functionality, like reading user input. This installment also introduces the concept of try blocks to handle exceptions, ensuring programs run smoothly even with unexpected user input. Furthermore, it covers the use of maps to store data as key-value pairs, which can be applied to create a simple login system. This foundational knowledge paves the way for Android app development using the Android SDK, where Java basics are combined with additional functionalities to create interactive applications.
