We've seen how to use generics and why they are important. Now let's look at the use case for generics with respect to a new construct in Java SE 8, lambda expressions. Lambda expressions represent an anonymous function that implements the single abstract method of a functional interface. T...
Actually both the forEach method and the Consumer interface have been added in Java 8, but you can already do something very similar in Java 5+ using libraries likeguavaorlambdaj. However Java 8 lambda expressions allow to achieve the same result in a less verbose and more readable way: 1 ...
companion object are introduced. The main advantage of this is that everything is an object. In Java, static members are treated very differently than object members. This means that you can’t do things like implementing an interface or putting your class ‘instance’ into ...
Preamble I was in the process of responding to christian.drumm 's excellent blog on Functional Programming in ABAP , when I realised that my mental ramblings should
Data visualization, a critical component of data science workflows, is well-supported in Python.Matplotliboffers a comprehensive set of plotting functions, while libraries likeseabornbuild on top of it to provide a higher-level interface for common statistical graphics. Interactive visualization libraries...

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 this course, you will learn how to use Java programming to address problems with Amazon Kinesis Data Analytics. You will also learn about the supported SDKs and see how they apply in real-world use cases through the Apache Flink libraries. Free Training Building Highly Connected Applications...
If you want to make it optional, you may want your viewmodel’s interface nullable and add a null check. Sounds too much right? But in kotlin it’s not. I am not aware about Java 8, but in kotlin all you have to do is to have a lambda as argument, and pass it as and once ...
Moment.js contains the entire interface by default. You can indeed optimize the package, but this requires additional steps. In date-fns you only load the functions that you really need. This doesn’t matter too much in a backend application with Node.js though, since the package size is ...
