  • It has a fast app building speed.

Disadvantages of Java

  • It requires more code writing which means more chances of having errors and bugs.
  • It is slower than Kotlin and requires huge memory.

About Kotlin-

  • Android app can be done using any language that can run on Java Virtual Machine (JVM), and Kotlin is also a JVM compatible language that aids coders in developing mobile apps easily.
  • JetBrains introduced this language in the year 2011 and got it got its name from ‘Kotlin Island’ that is situated in St. Petersburg Russia.
  • It was made to outmatch Java, but JetBrains didn’t make a new IDE. This is why Kotlin can be used in place of Java.
  • It is an open sourced language which can be statically typed for JVM, but if you want to use it for IOS development, you can do this by just compiling it with JavaScript or Native to write IOS codes.
  • Base Camp 3 app was made using this Kotlin language.

Advantages of Kotlin-

  • It has a lot of potentials when it comes to android application development, but it can also help you with backend projects.

  • Kotlin works well with all Java libraries, frameworks and JVM. So if you are working with Java, but want to create new modules using Kotlin you can, it will work as it is interoperable with Java.
  • It is free so you don’t have to send a dime on it, but you do have to learn it.
  • It has a huge library that will help you at any point.

  • You can write a single project using both languages, and it won’t be a problem.

Disadvantages that you might face using Kotlin:

  • Both languages have a concise syntax so while making a transition to Kotlin, the process of learning can be hard.
  • In most cases, Kotlin compilation speed is lower than Java.
  • The developer community is small as compared to Java so resources for learning might be less.
  • Kotlin is still being discovered, so finding a team leader for this might be an issue.

Final Verdict:

Well, Java and Kotlin both offer some great features. Java is an old language which most developers are comfortable with, is flexible and most importantly will not become obsolete anytime soon. So when you are struggling with Android Java vs. Kotlin for your next app development project, just think about these points:

  • Kotlin has many advantages, but it might pose a problem as making a sudden change to something totally new may have its own issues.
  • The team of developers may not be comfortable or able to adapt to a new language in such a short period of time.
  • For, a beginner in the android app development industry, Kotlin can be great as it is easy to learn and use.

So, which is the better language? -Well, it totally depends on your needs and comfort level.
