Kotlin vs Java comparison in 2021

In this study of the differences between Kotlin vs Java, we will discuss the important differences between Java vs Kotlin. But before we discuss the differences between Kotlin and Java, let’s first read “What is Kotlin?” and “What is Java?”.

What is Kotlin?

Firstly, At Google I / O 2017, Google has announced that it will begin sponsoring a new language for Android development: Kotlin. It is an open, mathematical programming language that can transfer Java bytecode to run on Java Virtual Machine (JVM) or Android, which integrates object-oriented features and applications.

Kotlin is being developed by JetBrains, a company behind IntelliJ Java IDE supported by Android Studio. They designed Kotlin to work fully with Java. Allowing developers to use any of the Java libraries and frameworks in Kotlin. As well as vice versa.

What is Java?

Java is a computer programming language. It enables editors to write computer commands using commands based on English instead of numeric codes. It is known as a high-quality language because it can be read and written easily by people.

Like English, Java has a set of rules that determine how to write commands. These rules are known as their syntax. Once the program is written, advanced commands are translated into numerical codes that computers can understand and process.

Main Difference

  • Kotlin combines features of both object-oriented and functional systems, while Java is limited to object-focused programs.
  • The Kotlin allows users to build an expansion function while Java does not provide additional functions.
  • Kotlin does not offer explicit modifications, and Java supports unconverted modifications.
  • There are no vain variables or objects in Kotlin on the other hand, Null variables or objects are part of the Java language.
  • Kotlin does not support static members, while Java uses static members.
  • In, Kotlin vintage variables are objects while in Java Vintage variables are not objects
  • Kotlin supports Lambda Expression and Java does not support Lambda expression.
  • The Kotlin does not require flexible data while Java requires specific data specifications.
  • Kotlin does not require flexible data details but Java requires specific data specifications.
  • Kotlin systems do not require semicolons in their system while the Java system requires semicolons.
  • The ability to write language allows you to use Kotlin directly in your Gradle building scripts while Java does not offer language writing capabilities.

Advantages

Java

  • Java is multiplatform and works on almost any device, server, or operating system
  • Its coding is strong, and it is not possible for Java instruction to damage memory or delete data from other OS X programs
  • Java is focused and makes it easy to create automated applications and reuse components that contribute to durability
  • Ready to use, and with Java, you’ll get a third-party code ready for use.
  • While comparing Kotlin vs Java performance, in some languages, Java is easy to use, integrate and make debugging and shipping easier
  • Java is an open language that guarantees security because most of its libraries are owned by reputable companies such as Google, Apache, and others.

Kotlin

  • Kotlin Application Delivery is quick to integrate, is lightweight, and prevents applications from growing in size.
  • Any chunk of code written in Kotlin is very small compared to Java, as it has less action and less code means fewer bugs.
  • Kotlin integrates code into bytecode which can be generated in JVM. Therefore, all libraries and frameworks have been developed in Java transfer and are working on the Kotlin project.
  • Kotlin script helps to set up projects in Android Studio with automated finishing services, and it helps to reduce the error detection time.
  • Safe at NullPointerException (The Billion Dollar Mistake).
  • Kotlin includes coroutines, as well as collaborations with Javascript for web development.

Disadvantages

Java

  • The syntax used by Java may be slightly more complex or complex while compared to other languages such as C + or Python.
  • With Java, it is not possible to access other content that may not be compatible with the device or device in use.
  • It is not easy to access new Java enhancements in mobile development.
  • There are times when Java creates problems with Android API design.
  • Java Testing Processing requires a lot of coding and carries a very high risk of editing bugs
  • Java is slow in relation to other programming languages and takes up a lot of system memory

Kotlin

  • The Kotlin is less popular, so the engineering community is relatively small compared to other well-established languages such as Java.
  • Kotlin compares weak patterns, and reading the first code becomes difficult to read and understand at first.
  • It has a small community of support as Kotlin is smaller than Java. In addition, it has several libraries, blog posts and tutorials.
  • Kotlin has a steep learning curve, and switching to Kotlin teams for good language understanding can be a real challenge.
  • Very few Kotlin engineers are available on the market. Therefore, finding an experienced counsellor is a delusion.

Does Kotlin Have a Future?

The answer is Yes. Kotlin’s influence in the IT sector has skyrocketed over the past few years. In fact, some major websites such as Pinterest, Flipboard, or Basecamp are already using it to support key agencies. The recent support provided to Google has been clear evidence that Kotlin has a bright future, as well as the strength to resist Java.

Sum up of Kotlin vs java

  • When you look at all the pitfalls of Java, especially the problem with NullPointerExceptions, Kotlin seems to be the best between the two.
  • Although Java is still the most important language in the development of the Android app as the Android OS itself is based on the same.
  • If you look to the future proof of your Android app development tools, then you should hire Kotlin engineers alike.
