Learn everything about classes, collections, properties, builders, and generic functions. Take the full course to learn the basics of creating apps with Jetpack Compose, Android’s modern toolkit for developing user interfaces. The onCreate() function is the entry point to this Android app and calls other functions to build the user interface. In Kotlin programs, the main() function is the entry point/starting point of execution.

When declaring a function, you can specify any number of arguments and theirtypes. In the example above, generateAnswerString() takes one argument namedcountThreshold of type Int. To call afunction, use its name, followed by the invocation operator (()). In theexample below, the answerString variable is initialized with the result fromgenerateAnswerString(). Rather than repeatingthe same series of expressions each time that you need a result, you can wrapthe expressions in a function and call that function instead.
