Summary
In this chapter, we explored the powerful concept of generics in Kotlin, a key feature that allows us to create flexible, reusable, and type-safe code components. We began with an overview of Java generics and discussed how generics in Kotlin offer a more concise and robust syntax. You learned how generics enable the definition of classes, interfaces, and functions that can handle different data types without compromising type safety, allowing for more efficient and reusable code.
We delved into the application of generics in functions, highlighting how generics improve code flexibility by enabling functions to work with multiple types. We also explored how generics work with properties, providing further flexibility when defining class attributes. A crucial part of this chapter was the introduction to variance (covariance and contravariance), which enables developers to manage type relationships effectively, ensuring compatibility between different generic types.
