Safe Casts

Last updated

What is Safe Casts?

Safe casts in Kotlin provide a way to convert a variable of one type to another, but unlike regular casts, they handle the possibility of the cast failing gracefully. Instead of throwing a ClassCastException if the cast is not possible, a safe cast returns null. This allows you to safely attempt a type conversion and handle the case where the object is not of the expected type without crashing your program.
