Writing Simple Yet Effective Codes in the Least Time
No matter how advanced platforms or technologies you get competent with, but basics are always tested when it comes about hiring a Java developer. This is the story even for the senior developers. It is thus advised to have a practice of basic programming skills. It is true indeed that the mode or approach of coding is not the same for every developer. But, time is a concern. It is thus essential to make sure that your code is easy to understand and execute.
A simple code can be executed in a much quicker time than the complex ones. And, the quicker it is developed and executed, the more effective from a budget point of views it gets. However, in the pursuit of making the program look simple or in the pursuit of finishing things quickly, one should not compromise the security aspects and quality. It turns meaningless if the job is done in a very nominal time, but has to be re-done.
Ultimately, the line between perfection and simplicity should be perfectly figured out. Make sure each side remains to equivalent level at either side of the line. Though it’s a matter of experience to attain this level of perfection at the professional level, the budding Java developers can also earn the knack upon handling or being part of the live projects. The best recommendation would be to go for internship programs.
It is suggested to bag opportunity of internship at start-up or mid-level organizations, as one can get greater exposure at these places to sharpen primary skills for Java developer. The challenges of finishing things within a confined time frame with perfection teach a lot to the concerned developer.

Bottom Line
Programmers do have to put a lot of passion and enthusiasm while writing codes. A Java developer has to take it to the other level. But, it is seen sometimes that a Java developer with a lot of zeal towards coding gets into a dubious phase of mind by going through the speculations of the future. Most prominent of such speculations being made is regarding the effect of Artificial Intelligence. Well, this is something too much to get worried about. It is certainly not going to happen shortly.
Moreover, the level of sophistication requires making the technology replace human brains, specifically for coding too higher. Yes, the developers should look for smart ways of coding, rather than depending upon the manual modes. In short, if the technology is something developed by humans (coders to be specific), its future can also be decided by the same. So, unnecessarily worrying is worthless!
If we talk about opportunities, one who gains these skills and also validates them with certification, is ready to reach the top. So, if you are aspired to have a bright career as a Java developer, go for a certification.
