Kodebits Day 96: Vararg Parameters [FREE]
Summary
The post demonstrates Kotlin’s vararg parameter by defining a total function that sums any number of Int arguments, showing that total(2,4,6,8) prints 20. It’s a quick intro for Kotlin beginners.
- vararg lets a function accept a variable number of arguments, received as an array.
- Calling total(2,4,6,8) returns the sum 20.
- Inside the function you can use standard collection operations like sum() on the vararg array.
Android developers learning Kotlin need to understand vararg for flexible APIs.
