Difference Between Kotlin and Java

There are heaps of inquiries Android application advancement competitors have, for example, 'Would it be a good idea for me to leave my continuous seminars on Java and decide on Kotlin?' and 'Would it be a good idea for me to pick Kotlin as my first language?'

Kotlin and Java

See, if you want a career in Android app development and you are learning Java for it, do not leave your course halfway. Complete your course and then move to Kotlin. Kotlin was made to interoperate with Java. Thus, you get a feature that helps you to convert your Java code to Kotlin or vice-versa without doing anything.

In Android application advancement, your Java abilities may be of no utilization in the coming 4 or 5 years, yet aside from Android application improvement, there are numerous things that no one but Java can do. Accordingly, great working capacity in Java can get you a lucrative work.

Additionally, assuming you are a finished fledgling and need to foster Android applications, then, at that point, experienced engineers will recommend that you ought to have some information on Java before you use Kotlin in light of the fact that it truly assists with learning Kotlin without any problem. Be that as it may, what are the significant contrasts among Java and Kotlin? For that, we have a committed Java versus Kotlin area, yet before that, we should get a short presentation of Kotlin and Java.


Main features of Java:

  • Simple to use.
  • Portable.
  • Supports object-orientated programming.
  • Secure compilation.
  • Has dynamic memory allocation.
  • Delivers high performance.
  • Supports multithreading.


Introduced by JetBrains, Kotlin is an open-source programming language. Kotlin was designed to interoperate with Java and JVM standard libraries. Following are some of the most popular Android apps made using Kotlin:

  • Evernote
  • Udacity
  • WeChat
  • Adobe Reader
  • Twitter
  • WordPress
  • Netflix
  • Expedia
  • Pinterest

Both the dialects are all set, yet assuming you need a programming language explicitly for Android application advancement, then, at that point, we propose Kotlin. In any case, imagine a scenario in which, in the forthcoming years, some other mobile operating system takes over Android? That would be terrible assuming you simply learn Kotlin.
