So, we will first look at operators that Kotlin allows us to overload, and depending upon our code suitability and use case we need to choose one operator. The Kotlin standard library also makes heavy use of operator overloading and provides (in conjunction with corresponding extension functions) a lot of “syntactic sugar”. Invoke Operator & Operator Overloading in Kotlin. Operator overloading can be done by overloading the underlying function for that operator. Kotlin allows us to provide implementations for a predefined set of operators on our types. Kotlin supports a technique called conventions, everyone should be familiar with.For example, if you define a special method plus in your class, you can use the + operator by convention: That’s called Kotlin Operator Overloading.. Operators like minus, plus or equals have been defined to work with a subset of predefined types. In our example, we are applying it with extension function combine() .
