Here is an example to show the use of conditional statements for the null check in Kotlin. A structural equality x = null is anyhow translated to referential equality x = null hence, it doesn’t make much difference whether you use = or =. We can also use = instead of = and != instead of !=. Here, we can use conditional operators = or != and execute the conditional statements accordingly. The elvis operator, :, can be used in Kotlin for such a situation. The easiest way to check null in Kotlin is by using conditional statements.

Use Conditional Statements to Implement a Null Check in Kotlin We calculate the current ratio by dividing current assets by current liabilities. If the input is invalid or cannot be converted to a Double, we throw an IllegalArgumentException. This article will teach you how to check for null in Kotlin and prevent NullPointerException errors. (.) and the null coalescing operator (:) to convert the input strings to Double data type and store them in the corresponding variables. Kotlin allows us to check null in various ways. Errors made with null references can cause application failure or even lead to system crashes hence, it is vital to check null references before running a program.

Several primitive types do not accept null and throw errors. Use the Elvis Operator to Implement a Null Check in Kotlin In Kotlin, nullability is intentionally treated to achieve null safety.Use Safe Calls to Implement a Null Check in Kotlin.Use Conditional Statements to Implement a Null Check in Kotlin.To enable this feature, you specify the following build.

With version 1.6.20 the Kotlin compiler is able to create proper standard executables for Android Native targets, whereas it previously could only generate a shared library to be used as a NativeActivity. Kotlin 1.6.20 brings many new features, including standalone Android executables, extended context receivers, native parallel compilation, definitely non-nullable types, and much more.
