Handling null + null in Kotlin: What Happens?

When developing in Kotlin, you're bound to run into scenarios involving null values. Kotlin's approach to null safety is well-known, but what happens when you try to add null + null? Let's explore this seemingly simple yet thought-provoking situation!

Kotlin and Null Safety

Kotlin’s compiler is strict when it comes to handling nulls. It doesn't let you add null values without clear handling. But what if you attempt to add null + null? 🤔 The compiler won't just sit back—it will prompt you to handle it, either by using safe calls (?.) or the Elvis operator (?:). This is part of Kotlin's type safety design.

The Case of null + null

When you try to add null + null in Kotlin, an error will occur. The language enforces clear handling of nulls to prevent unexpected behaviors or crashes in your application. This is especially important in Android development.
