All kinds of banking transactions need to be converted (from one format to another) the moment they get in or out of the ERP system. Since the number of transactions is super heavy in sectors such as Financial Institutes, and for that, it requires a language that can cater to those figures without any lags. However, it’s not just Java can that can perform the job, there are certain other languages too that do join the league, such as:

  • C/C++
  • GO
  • F#, etc

Missing Features in Enterprise Languages

After ages of usage, many corrections are required to fix the issues and make them flawless. We’re certainly talking about ‘missing features’ here. Let’s check out some of the most desirable features that are missing out from the current enterprise language today.

1. Structural Typing

Let’s understand with an example – the moment records get designed, the structural typing starts rejecting (being in favor of making records nominal type). It’s not wrong in saying that the Java system, has drastically evolved over the period of time – perhaps there have not been any changes made so far in general structural typing. 

This clearly indicates the idea that the name you input has importance and Java records are defined by more than just the number of types of their components.

  • Java being non-denotable types – One minor place where something that resembles structural typing continues to be vaguely visible in Java. These are really just an extension of the example (originally discussed in 2015).
  • Java holds the property of being the extended form of type inference (Java 10),  that uses var to reduce boilerplate in assignments. 

* Besides this, it’s only limited to the method in which the type inference occurs. 

2. First-class void

This functional-like feature – void type representation (like F# unit). This avoids processing differently that returns nothing and on the other hand, it returns something void X()). However, it allows more flexibility in generic handling. 

Action ==Func<unit>

3. Light Threads

When the developer is trying to trigger to pull out performance to reach its peak, it’s not necessary to rely on OS for any individual tasks, instead of it’s much more effective to create multiple threads and later interchange them for each allocated task. This can also be termed a green/light thread.

  • Talking about the enterprise applications, C#, or F# passes through it due to its built-in functionality whereas GO language allows extreme powered lights than can switch between CPU threads (due to its goroutines functionality).
  • On the other hand, Java does not provide this feature at all. Libraries like Vert.x support event-based dispatch to deliver the same peak performance and the same applies to C++ (with the library called Drogon).

4. Nullable Type

A compiler can actually prevent code from ever using null points by completely preventing null pointer references instead of throwing NullPointerExceptions. As a result, the same mistake that has been crashing software and causing security problems for decades can now be prevented completely at compile time.

Languages like C++, C#, Scala, and F# were not supporting NullPointerException earlier, and by the time, and updating, this issue has been fixed from these languages. However, this feature is still missing out from Golang and Java.

5. Primary Constructor & constextpr

The idea to introduce a primary constructor is that it eases the work by automatically winding up all subsidiaries. Developers often get exotic behavior while working with C++, where the specific value of any function appears in constant expressions. 

In general, it’s more about what and when the compiler is tracing a predetermined output, so compile time constant gets calculated. 

6. “nameof” Expressions 

This function is used to generate the name type as a string constant. Besides this, one of the major utilities of this expression is to maintain the argument-checking code.  Whereas, by using the latest version of C#, it is possible to declare the name of any method inside an attribute using the nameof operator. The reason – When both parameters (name and type) are used in nameof expressions, they are always in scope.

7. Auto default struct

A variable of a struct type contains all the data of that struct and this C# feature is considered compiler focused. Hence, as a developer, you would be able to know whether it’s being initialized or not. (if having a default value)

Besides this, the latest version of C# allows that field of any struct always initiates as their default value. 

8. Asynchronous Execution

This feature allows the user to specify an executor (specifically on which the stream will be executed) using the operator called as futureOperations on ReactiveSeq. Once the terminal is called – the user receives the desired results and the current thread can continue operating unhindered. 

Being an enterprise language, Go language does not provide desktop GUI support and lacks polymorphism which makes it hard to integrate with C++ codes. Besides this, there is an overhead calling C functions (as go lang’s runtime has to set up a native thread) to execute the call. 

We’ve come across these 8 missing features in the current enterprise language, that might get fixed (or not) in the future. These were the ones that are crucial, especially while building an enterprise application.
