Major Challenges in Java to Scala Migration Faced by Enterprises

Java has always been the developer’s preferred language for creating complex applications. However, with the introduction of Scala into the market, all businesses began to adopt it. Although we are well aware of the benefits of Java, Scala is taking over. So, tech giants select Java to Scala migration for robustness and efficiency. However, it is not as simple as it appears. Don’t worry. Let us take a closer look at them and see how they can be treated.

An overview of Scala 

Scala runs on the JVM and makes investments in multiple JVMs. However, people prefer it as improved Java rather than being qualitative. And it is why developers prefer to migrate from Java to Scala to build efficient applications. Furthermore, it adheres to a different functional programming philosophy.

Java, on the other hand, is an imperative language that explains what and how to do it. It works with elements, increments, processing, and so on.

In Scala, on the other hand, you write a function that includes an explanation for each element.

And it offers two advantages:

1. Code is too similar to the formula you want to program

2. Compiler causes fewer mistakes than the programmer during the explanation. 

Challenges faced during Java to Scala migration

Here are some roadblocks confronted during Java migration.

Limited developers

It may be difficult to migrate from Java to Scala because it requires expertise and data handling. So you’re up against some serious obstacles when it is to hire the right people for your company. And even if you find one, it is still challenging to fit in the Scala capabilities. It is still new and unexplored territory for some developers.

As a result, you spent a lot of time and money training them for your projects. However, finding skilled Scala developers presents numerous challenges. Scala concepts are not only complex but also significantly different from Java concepts. Scala may prove tough and adaptable to experienced Java developers in the future. This language will be difficult to learn until Scala becomes more widely used. And now developers are not trained, getting talented Scala-proficient developers is problematic.

Steep curve

Every language does not have a simple learning curve. Because of its length and language, Java code is difficult to comprehend. Scala, on the other hand, is both small and more extensive than Java. Though they can be considered advantages, they are not what they appear to be. You can hire Java developers for more technical guidance. Scala features and programs are complex. Because of its novelty and insignificance to the community. Even if newcomers attempted to learn it, they would find no assistance. Although the steep learning curve makes it difficult for many developers.

Discourage functionality

Functional thinking, or understanding of the functionality, is critical for developers. As previously stated, Java takes an imperative approach, which is much simpler. However, with Scala, this becomes more difficult. Scala allows you to return to an object-oriented paradigm whenever you want. It does not, however, encourage the developer to think functionally.

Immature tools

Scala will be difficult and irritating to use if you are a beginner. And it’s because Scala’s developer tools are as sophisticated as Java’s. But there’s no need to worry. It is possible to overcome it with time and experience. You can hire Java developers for more technical guidance. Scala will eventually become engaging, well-organized, and highly productive. Due to its benefits, Scala is adopted by well-known tech giants.

Scala vs. Java: Comparison you should know

Here are some of the differences between Scala and Java:

Complexity 

Java is a verbose language. We mean it literally because even simple programs require lengthy writing. Scala, on the other hand, allows you to write concise code. Although Scala programming is slightly more difficult than Java programming. One line of Scala code, on the other hand, can easily replace twenty lines of Java code. In Java to Scala migration, Scala enables developers to write code that is concise and compact. However, when compared to Java, Java is more beginner-friendly and has a lower learning curve.

Structures

Scala is very similar to Java, especially in terms of syntax. However, it contains many structures that Java does not. Scala, for example, provides automatic type inference and case classes. You can take assistance from Java migration services for guidance. Scala is also structured and can be converted to a domain-specific language (DSL). As a result, you can tailor Scala to meet the specific needs of your projects.

Concurrency 

Java developers must adhere to the traditional thread-based concurrency model. During Java to Scala migration, this method divides the program into several concurrently running tasks. Scala, on the other hand, employs a model in which each object is an actor with its unique behavior and mailbox. Furthermore, Scala simplifies thread communication and control while increasing efficiency.

Interoperability

Scala and Java are interoperable, and you can call Java functions from within Scala code. Even though it appears to be a little complicated. Because both Scala and Java have distinct programming features. But both languages implement interfaces, collections, annotations, and other features differently. 

Frameworks

Scala is less mature than Java. It has a broader set of tools, packages, and IDEs to support operations. Eclipse, Jenkins, Apache Spark, Android Studio, and so on. Scala is still in its early stages, and it encourages developers to create new tools and frameworks. Scala tools that are widely used include SBT, Gradle, ScalaTest, ScalaCheck, Scalaz, and others.

Conclusion: Scala is a successor of Java, but the migration between the languages can be risky. So, ensure to take to the assistance according to the challenges we have shared above. For more consideration, consult a Java development company for more projects.
