Scala vs Java

Think of your favourite Rocky film (yes, everyone has one) and you will instantly understand the mouth-watering fight that we have on our hands here between Scala… and Java!

In the blue corner is the 22 year old dominant “alpha”-language that has been topping the charts for years thanks to its versatility and sheer strength, Java. Meanwhile over in the red corner is Scala, the 13 year old upstart that has recently weighed in with an upgrade to 2.12.4 and is looking to prise the crown away from the reigning champion.

Java is not only the go-to programming language because of its versatility, it is also insanely popular amongst developers due to its ability to execute complicated tasks. But is Scala really the underdog programming language to finally dethrone Java?

Sure, Scala is great for addressing a load of issues that frustrate developers and admin alike when working with Java. But is that enough to persuade you about Scala’s potential?

Let’s take a closer look at why Scala may be the perfect alternative to Java.

Round 1: Asynchronous behaviour

Scala was developed with asynchronous processing in mind. Java wasn’t. This makes Scala more future-proof than Java was ever intended to be. In this way, with more people using Java to create apps, a lot of compromises are being made.

If you’re putting money, time and effort into an app do you want to make compromises?

Scala’s asynchronous behaviour means developers have greater options and ease when writing code.

Round 2: Stable and safe code output

Using Scala there is no need for explicit punctuation. Scala supports mixed capabilities and multiple inheritances that results in the developer being able to more easily identify flaws in the code. The more stable code means better security and smoother performance.

Also using Scala’s functional programming means working with greater stability and security by getting rid of all unwanted side effects. Phew, right?

Round 3: Kill Deadlock

Deadlock situations can be a drag and developers find them annoying to deal with. Scala offers not one, but several solutions that help you to avoid the dreaded deadlock incidents, such as null pointer exceptions.

Round 4: 3rd Party APIs

When developing an app the developer will have a crucial time, money and quality based decision to make about extra functionalities. Should they build their own extra functionalities from scratch or simply get a plug-in from a shady third party app?

Scala presents a clear solution to this issue by offering developers a range of built-in functions that they can call up on when building their app. The code used in the functions is precise to offer the developer greater control and the end user faster loading speed.

Round 5: Get to market quickly

One of the key advantages that Scala holds over Java lies in how it allows developers to use OO patterns - which are part of Java - and also Scala’s functional paradigms when building new projects. Functional paradigms are not part of Java and are one of the things that makes Java different, and better!

Using the two results in fewer lines of code and a speedier resolution for the initial development and subsequent testing.
