At the same time, allow implementing Kotlin. If any the elements of list matches the predicate, we should get true as return value from any(). Allow functions with more than 23 parameters, theoretically any number of parameters (in practice 255 on JVM).Call List.any() with predicate passed as argument.Define a predicate that the number should be even.
Returns true if at least one element matches the given predicate. Syntax 2 fun Iterable.any(predicate: (T) -> Boolean): Boolean Returns true if collection has at least one element. Any is a data type in kotlin, any type is super-type of all non-nullable types in kotlin. Note that it is not limited to third-party library class only! Main thing is, we can add a new function for any class in any other class too.The Kotlin List.any() function can be used to check if the list has at least one element, or if the list has at least one element that matches the given predicate.
If a field is repeated, the field may be repeated any number of times (including zero). Hybrid static, gradual and flow type checking Null safety No unsafe implicit conversions Unified top and bottom types Nominal subtyping with bounded parametric polymorphism and mixed-site variance. So now, we can add new functions even for the class that is in the third-party library. Use the Kotlin protocol buffer API to write and read messages. Kotlin has a type system with the following main properties. Such a function is called an “Extension function” and we can use such an extension function only inside the class where it is created. In kotlin, we can add a new function for any class in any other class too. We write more methods in the same class.īut, if the class is in the third-party library that we are using through dependency or in such a way that we cannot add new functions in such a class, we cannot modify that class.
Later, we realize that we need more methods for the class. Kotlin: Function type, function literal, lambda expression and anonymous function
