Introduction The following post illustrates the use of varargs (variable number of arguments) and array destructing feature in Kotlin langauge. varargs This feature allows multiple arguments of a same type to be passed to a method and not using a collection like Array or list. This feature in java is implemented using the 3 consecutive dots notation given below ... Java Example public String getByValues (String... values) { // ... } Array destructuring With array destructuring, we can be able to use the elements of the array without looping through or pulling out by index which needs careful access as we might get array out of bounds exceptions if not checked.
