Momo suicide game

Microsoft clamps down on sick 'Momo suicide game' in 'Minecraft' Microsoft is clamping down on the sick “Momo suicide challenge,” which recently infiltrated the wildly popular online game “Minecraft.”The tech giant owns “Minecraft” developer Mojang. The vile “Momo suicide game” has been garnering attention after spreading on WhatsApp, prompting police warnings. "Momo" is a viral challenge that asks people to add a contact via WhatsApp - they are then   urged   to commit self-harm or suicide. The "game" has fueled comparisons to the sinister " Blue Whale challenge " that led to reports of suicides in Russia and the U.S, as well as the online fictional character of "Slender Man." In 2014 two 12-year-old girls in Wisconsin  attempted to kill   a classmate in an attempt to please the horror character. The Buenos Aires Times recently  reported  that police in Argentina are investigating whether “Momo” is linked to the suicide of a 12-y...

Java Functional Interfaces

  The term   Java functional interface   was introduced in Java 8. A   functional interface   in Java is an interface that contains only a single abstract (unimplemented) method. A functional interface can contain default and static methods which do have an implementation, in addition to the single unimplemented method. Here is a Java functional interface example: public interface MyFunctionalInterface { public void execute(); } The above counts as a functional interface in Java because it only contains a single method, and that method has no implementation. Normally a Java interface does not contain implementations of the methods it declares, but it can contain implementations in default methods, or in static methods. Below is another example of a Java functional interface, with implementations of some of the methods: public interface MyFunctionalInterface2{ public void execute(); public default void print(String text) { System.out.println(t...

The Java 8 Stream API

1 Overview In this comprehensive tutorial, we'll go through the practical uses of Java 8 Streams from creation to parallel execution. To understand this material, readers need to have a basic knowledge of Java 8 (lambda expressions,   Optional,  method references) and of the Stream API. 2 Stream Creation There are many ways to create a stream instance of different sources. Once created, the instance  will not modify its source,  therefore allowing the creation of multiple instances from a single source. Empty Stream We should use the  empty()  method in case of the creation of an empty stream: Stream<String> streamEmpty = Stream.empty(); We often use the  empty()  method upon creation to avoid returning  null  for streams with no element: public Stream<String> streamOf (List<String> list) { return list == null || list.isEmpty() ? Stream.empty() : list.stream(); } 2.2. Stream of  Collection We can also creat...
