![]() In this Kotlin Tutorial, we learned about Kotlin is Operator, and how to use it to check an object conforms to a given type, with the help of examples. Output Is x object a String? false Conclusion To solve this, specify the type of x as Any, which we did in our previous examples. Println("Is x object a String? " + result) Since, Int and String are incompatible types, Kotlin would throw an error. And in the line 3, we are checking if x is String. It was designed to be statically-typed to remove boilerplate code notoriously found in Java but to also provide modern functional programming features. ![]() Also, no explicit type is specified for x. Kotlin is a cross-platform general-purpose programming language created by JetBrains, the company that also created IntelliJ IDEA. We have initialized a variable x with integer value. Kotlin: Incompatible types: String and Int context.startActivity(Intent('')) To launch the non-exported activity, your app should use an explicit intent instead: Kotlin Java // This makes the intent explicit. If the type of object is specified or derived implicitly by the value assigned to it, and if this type is not compatible with the type we are checking against, Kotlin would throw the following error. Kotlin Java // Throws an exception when targeting Android 14. We can also use NOT Operator ! with is as shown in the following program. We can use this expression with is operator as a condition for Kotlin If statement. Println("Is str object a String? " + result) Kotlin is an open source tool with 44.1K GitHub stars and 5.4K GitHub forks. In the following program, we will initialize a variable with String, and check programmatically if this variable is of type String, using is operator. Kotlin is a statically typed programming language for the JVM, Android and the browser, 100 interoperable with Java Kotlin is a tool in the Languages category of a tech stack.
