Commonly Asked Java Programming Interview Questions!
Java is a fine language and people are creating valuable software with it every day. However, there are a LOT of existing Java developers and many of them are in countries with fairly low labor rates. Since Java development has been around for a while, you’ll be competing with other developers with up to 20+ years of experience. Becoming a Java developer today means entering a highly competitive market with low prices and a high bar for being considered an expert.
In most circumstances, I’d say you should learn Python. It’s a good first language, since it will teach you good practices and it has a good progression from being able to write simple scripts to complex object-oriented systems. The barrier for getting some useful stuff done is very, very low. Even if it isn’t your first language, it’s a good choice. A lot of the interesting technologies coming out in the areas of machine learning, artificial intelligence, and devops are either based on Python or consider it a first-class citizen. Its close ties with academia mean that it will be interesting for some time to come.
I’d skip Javascript, if you can, but it is a requirement if you want to do anything web-oriented. What makes Javascript interesting is its ecosystem. It can be run on the browser and on the server, which is compelling. There is a rich set of third-party libraries, existing software, and developer resources to draw upon. Looking at it purely as a language though, it’s not as great. It is a language that is a lot of different paradigms mixed together - and not always gracefully. It’s a useful language, but not the best place to start for a new developer.
If you already know another language, I’d probably look at the following languages and see which one grabs your attention:
Go - Go comes out of Google and made by some really smart people. It has some interesting paradigms to it that will give you some new perspectives on programming (e.g., how it handles errors and concurrency). It’s super fast and has a great concurrency model. It is best if you are writing server applications, but it is a general purpose language, like all of these recommendations.
Rust - This is a systems-level language that is loved by developers that use it. It is in the same family as C and C++, but a lot more approachable. It is incredibly fast and can be used to write just about anything from device drivers to server applications to web applications. Given it is a systems-level language, it isn’t easy, but probably worth it.
Elixir - This language is gaining a lot of steam for its ability to create extremely scalable, fault-tolerant systems. It runs on the same virtual machine that Erlang runs on. Erlang was created to make sure things like nationwide telephone switching networks exhibited the sort of uptime that we have come to expect (read, 100% uptime, regardless of load). It also has the benefit of being a purely functional language, which will almost certainly require you to learn a whole new way of thinking about the language and programming in general. All that being said, it’s early days for Elixir. It has a bright, but not certain, future.
Haskell - If you want to become a better developer overall, I’d learn Haskell. It is a purely functional language and, arguably, the most rigorous (Elixir is similar, in these regards). Haskell will change the wiring of your mind. I’ve seen the leaderboard for some programming and algorithm competitions and the Haskell developers show up at the top of the list a disproportionate amount of the time. Haskell would be the programming equivalent of studying calculus, Latin, philosophy, or physics - most people don’t use it every day, but it makes you smarter if you’ve learned it. Landing a Haskell job means you’ll be working with top-tier developers. Demand for Haskell jobs is currently outstripping the supply. That being said, both the the supply and demand are relatively small compared to more popular languages.
