Iterator

Iterator

Trade-offs are super interesting and excellent exercises you can do to have better design and better coding. Let's say we want to do some simple algorithms that return vols from a String. So how many different implementations can we have? So easily we can think about some sort of Utils or generic function that can do the work for us. What if we cant to be Lazy or Early loading or be able to abstract the process? Well and Iterator is an interesting pattern that we can use to help us to abstract state and have more functionality around the data structure. So because there is the Pattern Iterator you might think that there is just one possible implementation right? Actually, there are several different implementations we can do and we can play with different trade-offs. So today I made 2 java videos to co trought this pattern and show some practicality in code. I hope you guys like it, let's get started.

Java Object Creation Patterns

Java Object Creation Patterns

Admin aaSunday, August 2, 2020

Java is an old language. 25 years now. Java has several limitations and issues however java is the robust and pretty well-stablished solution for backend, databases, Caches, Search Engineers,  IoT, and much more. Today I want to share some patterns about object creation. I highly recommend you read Effective Java book, which was a huge inspiration for this blog post. So I want to show you guys some useful patterns like Static Factories, Builder, Singletons and Immutable Objects.  So I made a quick video with code, let's get started.
