In this way, with a process that in functional programming is known as eta expansion, the name of the method is "expanded" by the compiler in the method itself that, as we have already seen, has the same signature of the only abstract method of the Consumer functional interface and then ...
We just need to add operators like DEFN and FN and ABAP will have made the switch - but see the comments above about ABAP functions and 1st class citizens... Functional vs Imperative Programming in General I have been a long time advocate of the functional programming paradigm, and at the...
Another great feature in Kotlin is the way it creates data classes. In Android most of the application are data driven which means we spend much time creating classes with only properties and fields to hold data. In Java this process is very tedious whereas in Kotlin this can be done in a...
Why we say AOP can increase modularity by allowing the separation of cross-cutting concerns? Suppose we have lots of methods all of which need common utilities like log, performance trace and authorization check. Before we use AOP, these utilities are scattered in every method: After AOP is us...
@FunctionalInterface public interface Predicate<T>{ ... } If we wished to traverse over each book title and look for those that contained the text "Java EE," we could passcontains("Java EE")as the predicate argument. The method shown in Listing 15 can be used to traverse a given list...
actions, we need our intermediates for authentication (as we don’t want un-authenticated requests coming in and creating users). Once we’ve created these authentication intermediates, we can just plug them in anywhere we want to turn a previously un-authenticated feature into an authenticated ...
Java Stringemail = null; System.out.println ("Alice's email address is "+ email ); produces this result: Plain Text Alice's email address is null In this specific case, the resultmightbe acceptable. But the language/compiler shouldn't decide this. As we have seen already, it would be...
The existing UI is awesome, why are you messing with it and ruining your product? I like the old textual panels, they are compact and descriptive, I can organize them to my liking. I don't like these large icons and I do not understand what do they mean. I need to click and guess...

In artificial intelligence and machine learning, Python is likely to remain dominant. As AI becomes more pervasive across industries, Python’s accessible ML libraries and frameworks will play an important role in democratizing AI development. We can expect to see more specialized libraries emerging, ...
