If you are a mobile app developer, Java was most likely your go-to language for building android apps. however did you recognize that new languages which may challenge Java's leadership within the android world area unit doping up everywhere the place? one amongst them is Kotlin, a comparatively new language some individuals believe is on its way to exchange Java on the mobile development scene.

Here's an in depth comparison of Java and Kotlin to assist you choose which language can work best for your next mobile development project.

Pros of Java

• Easy to learn and understand
  
• Works well for native also as cross-platform apps.
  
• Flexible – developers can run it in any browser window or a virtual machine. This comes in handy once you utilize code and update software.
  
• android depends on Java – the Android SDK contains lots of Java libraries to your aid. Also Java contains a wide open source system, partially as a results of Google's adoption of the Java Virtual Machine (JVM) for Android.
  
• Accelerated assembly inside Gradle.
  
• Java apps are a lot of compact – compared to Kotlin, Java apps tend to be lighter (even fully analogue); a Kotlin app that features advanced computing processes in its code will end up to figure slowly on user devices with low technical specs, if designed by inexperienced developers.
  
• Top development speed – Java ensures quicker build method than Kotlin.
  
• Java apps are lighter and compact, Java yields a quicker build method too, lease you code more in less time.
  

Cons of Java

• It’s slower compared to other languages and needs lots of memory.
  
• Java could be a type-heavy language, which implies you write a lot of code, increasing the probabilities of errors and bugs.
  
• Java experiences some issues with android API design because of inherent limitations.
  
• Java needs a lot of memory compared to different languages and thus tends to be slower
  

Pros of Kotlin

• Rather steep learning curve once change entire teams to Kotlin because of the language's pithy syntax (both a blessing and a challenge). 
  
• Slower compilation speed than Java (though Kotlin was shown to beat Java in some cases)
  
• Small developer community, which implies limited learning resources and problem to find answers to queries; one examine Stackoverflow can provide you with a rough plan.
  
• Experienced Kotlin devs are still a rarity, therefore finding a mentor for your team could be tricky.
  
• Android Studio’s auto-complete and compilation tends to run slower as compared to pure Java project.
  

Kotlin has actually taken the globe of android app development by primarily because of its innovative coding advantages. As a JVM-compatible language, Kotlin is beyond any doubt helpful to developers and higher than Java once it involves speed, potency and clarity of Java coding. however the choice of whether or not to switch entirely to Kotlin depends on the project needs and quality of developers.
