A wise man once said you are not a real Java programmer until you've dealt with a null pointer exception. Joking aside, the null reference is the source of many problems because it is often used to denote the absence of a value. Java SE 8 introduces a new class calledjava.util.Optiona...
This is very different from doing it in a procedural style using iterators where you often end up with one off errors, null pointers and a host of other problems. By eliminating the possibility of making them we can write code quicker and be more productive. Java 8 Streams and supplied ...
Java created a new way of programming. Moreover, it has a gentle learning curve and appears to successfully adhere to its own moto - “Write once, run everywhere”, which is almost always true; but Java problems are still present. I’ll be addressing ten Java problems that I think are ...
However, the documentation maintenance misses the task in practice, and the document becomes stale. It is where the docs-as-code automated test may help. In principle, it is possible to create a test checking the documentation and find discrepancies between the names in the code and the ...

Game Development Frameworks that support the development of games. FXGL - JavaFX Game Development Framework. JBox2D - Port of the renowned C++ 2D physics en...
Java 8 introduced functional interfaces to support functional programming paradigms usinglambdasandstreams, making the code more readable and expressive. These interfaces help in handling different real-world programming scenarios such as filtering data, transforming objects, executing operations, and aggregatin...
