Java vs Kotlin: Which One Is Better To Learn In 2022?

 What is Java?

Java is a common programming language that is class-based object-oriented and designed to have as few implementation dependencies as possible.

Java is the most powerful language and supports the development of multiple software applications operating systems as well as new programming languages and the reason for its outstanding superior performance is its features.

Pros

1. Java is multiplatform and works practically on any device, server, or operating system.
2. Java has strong security measures which make the chance of memory to get corrupt very low. Also, Java has a good coding base which makes it strong.
3. Creating Modular Applications in Java is very easy and since it has features like reusability, it makes the code even stronger.
4. Java has the power of using third-party code to make writing codes easier.
5. Java is fairly simple to handle and removing bugs from it becomes easier when compared to Kotlin.
6. The standards of safety in Java are of higher quality than Kotlin.

Cons

1. The syntax seems a bit difficult to understand when compared to languages like Python or C++.
2. In Java, some content may not be accessible to the user since it could be unfit for the device.
3. The accessibility of advancements in mobile development is not an easy task.
4. It has been noticed that Java has some issues with API design in Android.
5. Development in Java is mostly test-driven and requires the user to write more code and has a higher probability of bugs and errors.
6. Java is a tad slower than other languages and requires a good share of the device’s memory.

What is Kotlin?

Kotlin arrived on February 16 2016 and it was launched by JetBrains. Kotlin is a statically typed open-source programming language that runs on JVM and an official language for developing android applications. Kotlin actually gets fragmented into Java byte code for further compiling which caught the eye of a lot of Android Developers. There are a lot of features that make Kotlin different from Java.

Pros

1. Kotlin Application Development takes very less time for compilation, lightweight, and prevents applications from taking up more space. 
2. The codes written in Kotlin are smaller in size, meaning that it will have fewer bugs and will make debugging faster.
3. A bytecode, which is compiled by Kotlin can be executed with JVM. Thus, the libraries and frameworks from Java can be made to run in a project based on Kotlin.
4. Kotlin script is basically used for configuring projects in Android Studio for auto-completion aids, and also reduces error detection time during compilation
5. Kotlin is very much secure against NullPointerException. 
6. Kotlin incorporates coroutines, as well as interoperability with Javascript for web development.

Cons

1. Kotlin is not very well established. Therefore, the developer community is less in numbers compared to famous programming languages.
2. Kotlin matches weak patterns, which makes it very complex to read the code.
3. Since Kotlin is newer compared to Kotlin, it has a smaller user base and support community.
4. Kotlin’s steep learning curve and switching teams are because of language’s strict syntax can be a difficulty.

Many few Kotlin developers can be seen in the market. So, the job of finding a person experienced in Kotlin is a big challenge.
