First introduced to the world back in 1996, Java today is still very much in demand. Over 35% of programmers worldwide worked in this language in 2021. Moreover, it is firmly among the three most popular programming languages in the TIOBE index. What does it mean for you as a beginner Java developer? It means you’ll have to gain a competitive advantage to advance in your career successfully. Let’s take a look at the essential tech and soft skills you need to perfect.
