![]() It is essential to offer scalable solutions to the user. Kotlin string template also supports expression.Īvailable in Java too, but it doesn’t support expressions like Kotlin.Ĭoroutines are known as non-blocking or Asynchronous programming, which is an essential part of app development. Yes, there are two types of string literals in Kotlin such as escaped string and raw string. One can apply java static keywords with variables, methods, blocks, and nested classes. In Kotlin, we can use the companion object to create static members of the class.Īn object declaration inside a class can be marked with the companion keyword.Īvailable in Java. It allows users to assign null to any variable, but when accessing an object reference with a null value, it throws a null pointer exception, which the user must manage. NullPointerExceptions are a common source of frustration for Java programmers. If you want to print the null value for a variable, the declaration will be as follows: value num: Int?=null In case we try to develop, assign or return null values, the Kotlin code will fail. The variables in Kotlin are non-nullable, meaning they can’t be assigned to null values. Unfortunately, extension functions are not available in Java. If we need to extend the functionality of the remaining class, then it is required to develop a new class and parent class. By prefixing the name of a class as well as the name of the function, it is possible to develop extended functions. Kotlin allows the programmers to add new functionalities to an existing class.
