This utility would then be used by any developer seeking to making a status check.īefore getting started with the utility, we needed to create an interface that is similar to the Callable interface. The introduction of Lambda functions enabled us to create a utility that takes in a lambda function and a timeout configuration. There were multiple uses of this practice each with their own customized method of solving this, which leads to repeated code.

This would involve looping continuously until the operation has a successful status or the timeout is reached in the timer. A common functionality in the Okera code base is the practice of making a status check configured on a timer. Now that Java provides the flexibility, a good design will use either declarative or imperative approach based on which is more appropriate.

These two approaches represent different philosophies to software engineering with each having their respective benefits and drawbacks. In declarative languages, tasks are executed using functions that do not depend on local or global state This is unlike imperative languages where the end result can be influenced by the states. Functional programming is declarative in style, compared to the imperative approach that procedural language use. In Java 8, Lambda expressions were introduced, which is Java’s first step towards support for functional programming.
