Most probably, you will stand in between Java and Kotlin with a puzzled state to go with which one. To find out your path, let us scrutinize both in this blog.

What is Java?

Java is the most popular programming language which was coined by Sun Microsystems in 1995. It is a free source language which follows an object-oriented programming method. With Java, you can build a complete app that runs on a single computer as well as an app that works on distributed servers & clients in a network. 

It allows you to create any app and supports every device and operating system whether it is Android, Linux or Windows. By ruling the programming verticals for more than 25 years, java has set its foot path in almost every sector right from cell phone to internet, gaming platforms to supercomputers and laptops to  data centers.

Benefits in Java App for Business

1. Java apps are easy to easy to install and maintain
2. As it is maintained by experienced server administrators, breaching the  app developed by is difficult
3. Greatly suits for multiplatform & works on every devices, operating systems and server
4. It is fast, reliable & secure
5. It uses automatic garbage collection and memory allocation

Cons in Java:

  •  Java consumes more memory and works slowly while comparing to others
  •  Due to its longer code lines, there is increased possibilities in getting bugs and errors
  •  It provides no backup options and difficult to understand due to its complex code

Popular Brands that Utilize Java Code

  • Google
  • Twitter
  • Signal
  • Netflix
  • Uber(for map services, analytics & external technologies)

  2. Ternary operator
  3. Fields in Java are  nonprivate
  4. Checked Exceptions
  5. non-classes primitive types are available

Kotlin - Overview

Kotlin is an open source cross-platform programming language released by JetBrains in july 2011.  Basically, Kotlin is a free, general purpose and statically typed programming language with type inference. Unlike Java, Kotlin upholds several security and development benefits over Java.  Moreover, Kotlin is interoperable with codes of Java.  Moreover, it is simple, clean and upholds limited rules & formalities while comparing with Java.
In early 2017, Google announced Kotlin as its second official programming language to development android apps. Since then, Kotlin experienced an incredible growth and its demand among enterprise communities & developers raised greatly. According to recent report, JetBrains kotlins official original developers are looking to make this programming language to work on iOS too.

Benefits of Kotlin

1. Its code can be written in easier, clear and concise manner
2. IDEs in Kotlin assist developers to write code efficiently
3. Code’s in Kotlin is much smaller when compared to Java and so the probability to get errors is less
4. Kotlin has some extension functions that helps to build robust APIs
5. It supports functional programming which enables the developers to perform more task simply and consistently
6. With Kotlin, it is possible to work on Java codes
7. Apps developed in Kotlin are generally smaller in size 

Cons in Kotlin

  • As Kotlin appears few years back, it’s not so famous and so the developers utilizing Kotlin is sparse while comparing with Java
  • Initially reading Kotlin is slightly difficult and so it seems to difficult  understand it
  • As it has fewer developers in market, finding an experienced one to build Kotlin will be a challenging one

Furthermore, there is no solid reasons for the users to switch with kotlin as both of them are equally competent. Google confirmed that there will be future updates in Java as well as Kotlin. So we can expect both in future race too.

Java or Kotlin - Which is best to Consider?

Well the performance of an application is based several factors and features like code quality, reusability, etc. While comparing the performance of these two programming languages results that both Java and Kotlin are equally efficient and share the same scale. But we can’t pick both. Both are best in their ways, and choosing the best in based on your business requirements.
