Design patterns enable developers to speed up the development process by providing proven development paradigms. Reusing design patterns helps prevent complex issues that can cause major problems. Moreover, it improves your codebase, promotes code reuse, and makes an architecture more robust.

In this course, you will start with a gentle introduction of the Kotlin language. You will explore design patterns that are part of the best practices that help developers use Kotlin efficiently. Design patterns appeared in the era of object-oriented languages such as C++ and Java. You will learn the language features that Kotlin provides, which allow developers to program in a functional style and implement the design patterns.

After taking this course, you’ll be able to take your knowledge of Kotlin, design patterns, and associated best practices to the software industry and apply it to build reliable, scalable, and maintainable projects.

Kotlin Design Patterns and Best Practices

If you're a Java developer, you may already know that stopping a thread is quite complicated.

For example, the `Thread.stop()` method is deprecated. There's `Thread.interrupt()`, but not all threads are checking this flag, not to mention setting a `volatile` flag, which is often suggested but is very cumbersome.

If we are using a thread pool, we will get `Future`, which has the `cancel(boolean
mayInterruptIfRunning)` method. In Kotlin, the `launch()` function returns a job.

This job can be canceled. The same rules from the previous example apply, though. If our coroutine never calls another `suspend` function or the yield function, it will disregard `cancel()`.

To demonstrate that, we'll create one coroutine that yields once in a while:
