Kotlin
现代 Android 开发。
Kotlin is the language Google recommends for Android, and it runs everywhere Java runs. It is concise, protects you from null crashes and works side by side with Java code. This course starts from zero with Kotlin 2: values and string templates, null safety, if and when expressions, ranges and loops, functions with default and named arguments, then classes and data classes, collections and lambdas, extension functions, a gentle first look at coroutines and a glimpse of Jetpack Compose.
Every lesson is short and packed with quizzes, so you learn by doing.
