So let’s get on a quick nerdy tour of Android languages…

What is Kotlin – A Quick Overview

Well, the first and the foremost Kotlin is an official Android language and is developed by Jetbrains, famous for its IDE named IntelliJ IDEA. In simpler words, it is a high-level, statically typed programming language, which runs on JVM-Java Virtual Machine and is easy to be compiled to JavaScript source code or handle the LLVM compiler infrastructure. In addition, it includes an improved syntax that further helps in triggering concise expressions and abstractions. No prize for guessing but it certainly removes the clutter of boilerplate code and makes the process as smooth as possible. 

Thus, android development with Kotlin gives you an extra edge to compete with the trends in the market. Many businesses have incorporated this programming language to create their first Android app. By contacting the best mobile app development company, you can start developing your business app project.

How Kotlin Advances Android App Development – Top Benefits of Kotlin

1. Completely interoperable with Java

The Kotlin programming language is completely compatible with Java which is an additional benefit. Developers using Kotlin may use all Java frameworks and libraries while producing more readable and concise code. Therefore, Android engineers can use both languages while developing a mobile app and migrate their Java programs to Kotlin. 

Talking about Java interoperability, you can easily convert a large Java-based project to Kotlin one file at a time. And you’ll see that everything is still successfully compiling, even if it has millions of lines of code. This is because the top app development company uses Java to maintain legacy projects and write the code in Kotlin. This way, it becomes easy to develop a robust Android app. 

2. Requires fewer lines of coding

Less code is good, but readability is something you shouldn’t miss considering. It gives you enhanced and improved access to code. And when you use Kotlin, you get both; less code plus readability. Moreover, JetBrains made every effort to keep the language as succinct as possible, and they succeeded.

In addition, when properly implemented, less code produces fewer bugs. And hence, you can concentrate on more important tasks when you delegate some tedious coding tasks to the framework. Kotlin facilitates high readability and simplicity for the Android app development process

3. Smarter and Safer Compiler

With the inception to provide a good and safe compiler, the Kotlin language development team worked hard to create this programming language. Being one of the most advanced programming languages for Android app development, here are some aspects of the compiler in Kotlin:

  • Error detecting at compile time, not at runtime. It lets developers leverage the fail-fast principle. 
  • Performing multiple checks to reduce runtime errors and bugs in the code. 

Moreover, it prevents common mistakes during program execution because of semantic integration. 

4. Resolves Developers’ Challenges

Not academics, but the business world gave birth to Kotlin. To work with its flagship product, IntelliJ IDEA, which is entirely built in Java, JetBrains needed a more accessible tool.

They looked into the alternatives but were unhappy, so they created their programming language. The objective was to create a powerful, efficient tool to use with Java and function anywhere that Java could.

Kotlin, therefore, helps programmers overcome their problems. The type system, for instance, aids in preventing null pointer exceptions. But unfortunately, while vast codebases and APIs, which support null, are more common in research academic languages, this is of no value to software engineers who work with them.

5. Safer Code

The fact that Kotlin’s code is shorter has previously been determined. Consequently, a precise, compact, and brief code is inherently safer. In addition, it allows for fewer mistakes because it is more compact. Not to mention that Kotlin avoids typical programming errors by design, resulting in more occasional crashes and system breakdowns. 

In addition, it helps in preventing errors in design. As soon as the app development process starts, developers can find the potential problems that their code might cause. Therefore, Kotlin enables developers to exercise caution and produce more reliable and stable code.

6. Has Null in its type system

Last but not least, why Kotlin is the most preferred language for Android app development is NULL references. It is one of the biggest roadblocks to writing high-quality code. When writing code in Java, null reference results in a null reference exception (NullPointerException -NPE). The development team of Kotlin had the aim to design a language eliminating NPE from the code. 

So, using Kotlin has several benefits, and if you want to develop an Android app, Kotlin is the trendiest programming language to use.

What is Groovy – A Quick Overview 

Groovy is a testing-oriented development language, having a syntax that supports running tests in IDEs. The best feature it has stated is that it supports both static typing typical for Java and dynamic typing similar to Python. 

If we compare Kotlin vs Groovy, Groovy came into existence much before Kotlin and can be used as both a programming language and a scripting language for the Java Platform. It is also compiled to JVM-Java Virtual Machine bytecode and interoperates flawlessly with different Java codes and libraries.

Even the cost to develop a mobile app with Groovy is not significant. Also, Groovy has become one of the popular choices of business owners to build an app. 

Further, it also has a knack for supporting native markup languages like XML and HTML and domain-specific languages. 

By contacting any android app development services, building an app with Groovy will become easy for you. Meanwhile, you can check the benefits of using Groovy for application development.

Top Benefits of Groovy for App Development

1. Support for Static and Dynamic Typing

Languages that use static typing do type-checking during compilation rather than execution. For example, Java is a statically typed general-purpose language. On the other hand, syntaxes with dynamic typing, like Groovy, do the check as the program is being executed. Moreover, Python is an example of a dynamic typing language. However, Groovy can help to work for the development while fulfilling both typing needs. 

2. Concise, Brief, Direct Syntax

Another advantage of using Groovy is that it allows developers to build projects faster and easier. It offers concise, short, and direct syntax, which reduces many hassles. Any top Android mobile app development company would prefer this programming language because of its advantages. 

3. Flat lLearning Curve

You will get a short, simple, readable, and expressive syntax if you want to develop an app using Groovy. Such syntaxes are easy to learn, and creating a product won’t be a problem. 

4. Support for Unit Testing

Groovy is a testing-focused development language that enables you to develop robust applications. It is a syntax that supports testing in Java application programming tools like Ant, Maven, or integrated development environments (IDEs).

5. Native Support for Regular Expressions

When it comes to creating regular expressions, Groovy syntax helps to do the task very straightforwardly. There are three operators for regular expressions in this programming language that you should know are:

  1. The operator regex =~.
  2. The operator match ==~.
  3. The pattern operator ~String.

Groovy also provides native support for markup languages such as XML and HTML. With this, developing an Android app doesn’t seem like a difficult task to do. 

6. Native Syntax for Associative Arrays and Lists

Arrays are typically assigned to variables in programming. These factors and data are frequently linked. Developers occasionally link the data to different array elements using an index as a connecting element. An associative array is a programming construct that can organize data.

7. Support for Language-Specific Domains

A programming language or specification designed to solve particular problems using a specific approach is known as a domain-specific language. The converse is true of general-purpose grammar like Java, C, or C++. Nevertheless, it somehow offers a broad framework for resolving universal problems.

Comparison Between Kotlin vs Groovy

1. Technology Ecosystem

Some people might find it challenging to comprehend an ecosystem in the context of software and programming. But even those with a basic understanding of software architecture and the surrounding environment can pick it up quickly. Thus, a software ecosystem refers to everything involving language, syntax, scripting, and an open-source community to make a software project workable and sync into production. Based on this, given is the comparison between Kotlin and Groovy: 

  • Kotlin– It has limited libraries for the developers. Using the libraries and test frameworks, one can develop an Android app. 
  • Groovy– It holds a wide variety of build tools, test frameworks, GUI building, and code analysis. Also, it offers asynchronous code, concurrency, and parallelism.

2. Based on Features

The days of developing Android apps using only one language are long gone; Kotlin and Groovy now occupy a significant portion of the market. JVM, short for Java Virtual Machine, is the most widely supported language in the Android ecosystem; fortunately, both Kotlin and Groovy support JVM. Understanding the features of Groovy and Kotlin makes it clear which programming language adopts a practical approach with standout features that frequently benefit developers. So, check the below feature comparison of both languages:

  • Kotlin– Well, it reduces runtime crashes, easy for interoperability with Java, safe and reliable, smart cast function, low cost of adoption, statically typed, extension function, high-order functions, Null safety, Smart Cast, and many others.
  • Groovy– Holds incredible features such as runtime and compile-time meta-programming, closures, builders, static compilation, functional programming, static and dynamic typing, regular expressions, supports XML/HTML, and operator overloading among many others.

3. Coding Parameter

  • Kotlin– You’ll be shocked to learn that Kotlin isn’t its own programming language. It is just one more tool available to programmers that use Java to write programs. Since Java has long been the programming language of choice for developers, the majority of contemporary languages try to mimic its features; one such language is Kotlin. It is a pragmatic language, which makes it easier for the developers to use it, having knowledge of Java coding.
  • Groovy– On the other hand, Groovy is a flexible and dynamic language. As a result, promoting it as a scripting language for all Java platforms will be appropriate. The code parameters used by Groovy are compiled to Java bytecode, and it has features that are similar to Python, Ruby, and Smalltalk. However, compared to Java, this object-oriented programming language is shorter and more meaningful. It requires lesser lines of code and makes it easier for developers to read and learn it. 

As a result, if we had to choose between Kotlin vs Groovy for performance in terms of coding parameters, they would both rank equally high. 

4. On the Performance Scale

As we continue discussing the differences between Kotlin and Groovy, it seems essential to base a comparison on the performance times of the two languages. Since Groovy and Kotlin are based on Java, performance is a factor that we can’t ignore to find the best option for Android app development. On the other hand, both programming languages’ technical responses are respectable. So, have a glance at the performance scale of both languages. 

  • Kotlin– The performance of Kotlin is similar to Java. Kotlin is popular among programmers because it is quick, adaptable, cutting-edge, and secure.
  • Groovy– Compared to Java or Kotlin, Groovy is slower, as there are additional runtime checks. Groovy has a flexible, Java-like syntax, it is dynamic and closely related to Java, and most programmers prefer it.

Kotlin Vs Groovy – What’s the Final Take?

Hmm, TBH both Kotlin and Groovy are developer-friendly languages, and the major difference lies within the compilation only. Further, they both are interoperable, making both of them co-exist in the same application. So both of them have their own advantages that can be picked to fill your bucket list. Of course, choosing between Kotlin vs Groovy depends on your choices. Still, you wonder which is better; you need to get in touch with your developer to get recommended the best choice for your Android project.
