After covering Python as the foremost emerging language in our first Learning Path, we decided to pick Java as an established champion in the world of programming languages.


I think any new or old modern day programmer needs any introduction on Java. One of the most impactful languages of the 20th as well as the 21st century. From countless websites, web-applications and even our own beloved Android is based on Java. Talking about Job prospects, even by the latest Tiobe Index of Mar 2019, Java comfortably sits as the number 1 language. So if you want to learn Java with job prospects in mind, you can’t go wrong with this choice. Application of Java as a programming language is possibly the widest and is used by almost every Fortune 1000 companies.

Complementary Skills To Brush Up for a Job

Incidentally, the job market for programming is such that one language alone may not suffice all the requirements for a role. It needs to be paired with some complementing language or technical skills which would help you work in a company with multiple systems. So in order to increase your job chances, you would want to pair them with at least one (if not more) additional language skills for coding:

  1. Basic HTML, CSS ( for web development)
  2. Basic Javascript, Jquery (for web development)
  3. Basic SQL (must have for any role)
  4. Pig, Hive, HBase (for Big Data roles)
  5. Linear Algebra (for Machine Learning roles)

Popular Job Roles To Target with Java

We all want to achieve something after learning something, especially something as rigorous as programming. It’s no secret that most of the jobs of the future will be centered around computer programming, coding, and other related skills. Of course, many learn out of their own interest or to make their own applications. But if you are someone looking for a job after a significant learning effort, then these are some of the job roles you can target with Java as your programming skill:

  1. Software Engineer
  2. Web Application Developer
  3. Big Data Developer

This article is second in our new series of ‘Learning Paths’, to help students learn a new language in a planned manner. It’s an initiative we are taking based on the pain points we uncovered after talking to some of our users. We figured it would help students to have some example courses to look for whenever interested in a topic of their choice. Also as a next step what other complementary skills they might need when targeting a particular job role in mind.

However, there’s always a scope to do better. So it is awesome if you would like to share any ideas to help us plan our next article better. Be it the next ‘Learning Path’ in the same series, or some other area where we can help better. Quickcode will always be welcoming of your ideas, appreciation, and feedback of any kind.
