Functional programming is a very powerful paradigm that makes code more concise and easier to understand.
In Java, the “Function” functional interface can be used as a first-class citizen function, meaning that we can pass a function to a method and declare it as a variable, giving the developer a lot of power.
And now it’s time for you now to test your abilities with lambdas and functional interfaces!
Asynchronous CompletableFuture San Francisco Adventure Java Challenge
The Completable Future feature is powerful for better performance when running asynchronous methods.
In Java 5, there is the Future interface, however, the Future interface doesn’t have many methods that would help us to create robust code.
To solve the limitations of the Future interface, we have the CompletableFuture API with methods that will help us to build reliable high-performant software.
Now that we had the intro about CompletableFuture, let’s go to the Java Challenge!
