Javarevisited

 One of the things I tried with this roadmap is that to keep the exposure as short as possible, I have avoided mentioning many alternatives, particularly when it comes to libraries and tools, and stick with industry-standard tools and libraries.

I have kept it simple so that most of the people can follow it and only included the essential stuff, but if there is enough desire, I am thinking to post The Java Developer RoadMap 2.0 to add some advanced things like JVM internals, Profiling, Java 9 Modules, Cloud Native Java, different cloud platforms like AWS, GCP, or Azure, and more advanced tools like Chef for DevOps and much more.

If you are interested, you can find a more exhaustive list of separate blog pots, which I have listed in the further learning section. Anyway, let's go through this Java Developer RoadMap to understand how to become a Java developer in 2021.

Btw, you by no means need to understand everything on this roadmap to become a rockstar developer. In fact, you don’t even need to take them that seriously if you don’t want to. Instead, use these maps as a starting point to help guide your learning as you go. Read more: Java online course

6 Mandatory skill for any Java developers

Before going to Java-specific stuff, let's go through some mandatory skills which are required for both core Java developer as well as full-stack Java developers. These are the essential skills for any programmer or software developer and will serve you for a long time. 

1. Git & Github

One of the most popular version control system. It's just not possible to live without Git anymore. You can check out The Git Complete Guide on Udemy to start with. Read more:Java online course

2. Linux

Not just a web developer but for any programmer, the Linux command line is very, very important, and I strongly recommend you to spend some time learning them. You can use these free Linux courses to start learning Linux. Read more: Java online course

3. Data Structures and Algorithms

These are the building blocks of any program, and a good knowledge of Algorithms and Data Structure is vital for your next job or doing well in your current situation.

You should at least be familiar with essential data structures like an array, linked list, hash table, binary tree, queue, stack, and graph. Read more: Java online course

Enforcing Java Singletons is Very Hard

  Background A  singleton  is a class that is instantiated exactly one time and can be used to represent "global" or system wide components. Common usages of singletons include loggers, factories, window managers or platform components. My general tip is to avoid using singletons when possible, because it is difficult to break out or override functionality and also to write test mocks and they also tend to create a bad over all code structure. As it turns out in this post, they are also insecure. know more java training Many efforts has been made to devise good singleton patterns but there is one surprisingly easy and efficient way of doing it. However, there is really no rock solid way of guaranteeing that the  singleton  integrity is not breached. Read this post and see if you agree. The Final Field Scheme This solution relies on keeping the constructor private and exporting a public static final member to provide singleton access like this: public class FooSi...

5 tips for proper Java Heap size

  Determination of proper Java Heap size for a production system is not a straightforward exercise. In my Java EE enterprise experience, I have seen multiple performance problem cases due to inadequate Java Heap capacity and tuning. know more java training  This article will provide you with 5 tips that can help you determine optimal Java heap size, as a starting point, for your current or new production environment. Some of these tips are also very useful regarding the prevention and resolution of java.lang.OutOfMemoryError problems; including memory leaks. Please note that these tips are intended to “help you” determine proper Java Heap size. Since each IT environment is unique, you are actually in the best position to determine precisely the required Java Heap specifications of your client’s environment. Some of these tips may also not be applicable in the context of a very small Java standalone application but I still recommend you to read the entire article. Future artic...
