What are some less popular fields of research in CS that you think more people should know about? Posted: 14 Feb 2020 08:38 PM PST As an undergraduate, the topics of research I always hear about are AI/ML and Security. What are some other topics in the field of Computer Science that you think people should hear about? submitted by /u/HumanGarbage2 [link] [comments]

ELI5: Decorator design pattern vs inheritance Posted: 14 Feb 2020 05:24 PM PST I was reading about the Decorator design pattern. From reading about the design pattern, what it does is it allows you to extend the behavior of an object/class by placing the object/class in a wrapper like public abstract class A{ public abstract void doStuff(); } public ADecorator extends A { protected A aInstance; public class ADecorator(A aInstance){ this.aInstance = aInstance; } public void doStuff(){ //Custom do stuff behavior aInstance.doStuff(); } } By doing this, you can dynamically add behavior to the wrapped object and still delegate work to the wrapped object . It sounded a lot like inheritance. Can someone give an ELI5 explanation of when should you use this design pattern vs when should you use inheritance? You could accomplish by just having a class extend A and just putting the custom behavior you want in the doStuff of the class that extends A submitted by /u/Truetree9999 [link] [comments]
