Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
Design Patterns
-
I have been following the mooc java-1 from few days and i am on part-3 i want to ask some questions
After that, more practice, and then Design Patterns (as in the famous book of the "Gang of Four": "Design Patterns: Elements of Reusable Object Oriented Software"). Here I'd recommend "Head First: Design Patterns" and Java Design Patterns as well as Refactoring Guru (the sites are more reference than course).
-
I made java roadmap website! Any feedbacks welcome!
For Design Patterns - any resource recommendation that misses Java Design Patterns and Refactoring Guru (also for Refactoring) as well as *Head First: Design Patterns, has failed.
-
How do you structure code?
A massive list of design patterns and how they could be implemented (in Java) can be found here.
-
Resources to learn how to create a 2D game engine with CPU rendering.
https://java-design-patterns.com/ has example code for things like object pools that can help with memory management.
-
What are some book recommendations that don't require a specific language.
Sidenote: I would not really use the GoF Design Patterns book anymore. Too dry. I would use "Head First: Design Patterns" - much more modern, much easier to read, or Refactoring Guru or Java Design Patterns (uses Java, but again, only for illustrations).
-
I want to get a book on design patterns. Would you recommend the GOF book or the Head First design patterns one?
Also: https://java-design-patterns.com and https://refactoring.guru/design-patterns
-
How is an Observer pattern possible?
Use either Java Design Patterns or Refactoring Guru. Both resources are far higher quality than yours.
-
Are there any quick videos/articles/resources that go over stuff not explicit taught in University?
Java Design Patterns
-
Learn design pattern !
Java Design Patterns - IMO one of the most accessible sites with very easy explanations
-
What are the Java design patterns suitable for the below functions in an E-commerce application?
A hint: go to Java Design Patterns and go through the patterns to figure what could fit.

Java dynamic SPI registrations
I'm working in a spring boot based environment using a setup similar to pf4j where additional JARs can be loaded at will during runtime. Each plugin may implement a set of interfaces which are then dynamically registered in the Applications IoC. The important part is: Each jar is loaded within a separate ClassLoader.

PF4J and Clojure
Hi everyone! Recently I've needed to figure out how PF4J library can be used from Clojure, and it was not very straightforward in some parts. There were almost no information on using PF4J from Clojure, so I've wrote this post, explaining what I've did to make things work by creating example plugin, as per PF4J demo application. Hope it will be useful for someone!
