Introduction In a previous article, I discussed how to efficiently store strings in a hash map and search for them without worrying about case sensitivity. While you could still use the same wrapper class, there are at least two potential downsides to this approach.

Introduction By default, Microsoft SQL Server processes strings without considering their case sensitivity. Java, unlike Microsoft SQL Server, is case-sensitive which can result in problems. One such example is with email addresses, which are inherently case-insensitive.

Introduction Modern hardware is very good at predicting the next instructions to be executed. This kind of prediction allows CPUs to do more work in less time. One of the strategies that hardware relies on is data locality.

Extracting archive files without controlling resource consumption is security-sensitive and can lead to denial of service. Our code executes on servers, but you should know that servers have limits. Based on this, check how many hardware resources your code can consume.

Here are several reasons: We work in teams. The better we know how to communicate with people in a team, the better we will be. Remember, your whole company is one big team. All languages compile at the end in machine code.

Introduction We need fast-build pipelines. This is because we need fast feedback from our pipeline in order to be more productive. If something is wrong with our code, then we want our pipeline to fail fast.

I have attended the workshop that is organized by the ITKonekt. The workshop was about efficient coding practices for best performance in Java. Java Champion Victor Rentea did a great job explaining all java internals, tools, hibernate, threads, collections, garbage collections, and much more.

Based on my previous experience, I created a list of 10 mistakes that developers made, preventing them from being a great developer. Here is the list:

1. Not writing unit tests Developers that don’t write unit tests produce more bugs from the code they write and maintain.

As a Java developer, I always look for ways to improve my coding skills. I heard about functional programming (FP) back when I was a student. Then, FP was not very popular and most developers considered code written using FP to be slow. Time has changed and today FP is very popular.
