![]() In this Kotlin Tutorial, we learned what a Kotlin with function is, and how to use this to create a scope (with-block) for an object (receiver) and access its members and functions. And Interface/Class delegation is the other. As another example, some of the dependency injectors for Kotlin support this model by delegating the getter to receiving a value from a registry of instances managed by the dependency injection engine. ![]() Now, let us return length of the receiver object str from the with-block. Here you delegate the getter/setter to another class that does the work and can contain common code. Kotlin is 100 interoperable with the Java programming language and major emphasis has been placed on making sure that your existing codebase can interact. In the following example, we will return lowercase value of the String from with-block. Good knowledge of Kotlin or Java Profound understanding of Object-Oriented programming Experience with code profiling and performance tuning Good understanding of Software Engineering Principles Adapt and deliver on time working in a fast-paced agile environment Other Qualifications (nice to have): Experience Building APIs (REST and/or. Just place the return value as the last statement in the with-block. Because this book provides only a quick reference to the Kotlin language, its intended for developers who have experience in other programming languages and. You dont need to know their whole tech stack however experience with Kotlin would be highly valued. They use Microservices backed by Docker, Kubernetes, and GCP. Their tech stack is Kotlin, Python, Spark, GraphQL, and React. Output Hello World! Return Value from With-Block This is the opportunity to join a small team of four Software Engineers focusing on full-stack development. To access receiver itself in the with-block, use this keyword. Come join our team as an intermediate Android (Java and Kotlin) developer. Inside the with-block, we have accessed length property and called uppercase() function of the receiver object str, with actually referencing the object str again like str.length or str.uppercase(). ![]() ![]() In the following example, we will pass a String value for receiver object to with() and access the properties and functions of the String in the block.
