Nice to see these types of articles; from a professional Java developer of 15 years! The problem is, Java has such a large scope that getting these right is tricky. For example, there's the simple concatenate with + of strings, but that is highly inefficient. Then you have your .concat call, which is better. However, if you are writing optimised code, it's better trying to use a StringBuffer, as it is designed to operate more efficiently with the garbage collector... I will have a poke around at your other articles. Thank you!
Thanks @sp33dy, I see you have a great knowledge as you have rightly said, I have addressed the Other methods in other tutorials and i Hope you see them also. StringBuffers are safer to use when it comes to more technical work.
Thanks for stopping by.
Although I'm a professional Java developer, I've decided to focus on Godot Engine and providing tutorials for it. Primarily as I've started writing games. So I want to share the love there. Please do drop by.
