Java VS Kotlin - Which is better?

Most people have a doubt that which programming language is better Java or Kotlin for android development(Java vs Kotlin-Which is better? ). Now both languages are awesome but Kotlin has a slight advantage over java because it the purpose it was developed was to overcome the hurdles developer's were facing when they worked on Java.

But wait, even though kotlin has advanced features and better user interface than java but still there are certain spots where kotlin is weaker than java. As the name of topic suggest Java VS Kotlin - Which is better? ,we will be discussing the advantages and disadvantages of both languages and at the end we will discuss the conclusion.



Advantages of Kotlin over Java

1. The code user writes on kotlin appears more expressive and concise which means users can write more functionality with much less code.

2. The compiler of kotlin is much better than java . it has following features:-

• The compiler detects error at compile time and not runtime.
• The compiler of kotin performs lots of checks ,thus reduces runtime error chances .

3. Another major advantage of kotlin over java is that it was designed to enhance the productivity of the user.

• Firstly it has a clear ,concise ,short and expressive code as compared to java.  
• Other factors that enhance its productivity are Object declaration , parameter values, extension functions.

4.  Kotlin is powered with functional programming with which developer can solve problems more easily and allows him/her to use functions more concisely. This feature improves performance and consistency of developer.

5. This advantage is one of the biggest advantages of kotlin that it's null safe. In java we have a NullPointerException but it is removed in Kotlin and it saves a lot of debugging time. In kotlin, if you want to access a null safety operator than you use "?." which consider the object is null.

These were some most important advantages of kotlin over java but besides these advantages there are 100s of advantages of kotlin but those are syntax, feature related advantages.   

Advantages of Java over Kotlin

1. Java developer's community is very large because it has been in programming world since 1995, But Kotlin is a new language which came in 2011 so its community is small.

2. In kotlin there is definitely a steep learning curve. It's simple syntax is easy to learn but it requires some learning up-fronts.

3. One major drawback of kotlin over java is its large file package size of .apk. The size grows due to the runtime and Kotlin standard library. Although the additional size makes less than 1 megabyte,  for large apps this extra size can result in fewer downloads eventually.

4. Another major drawback which is faced by kotlin developers is that the compilation time in kotlin is more than java. Although kotlin is faster than java but sometimes  developers have reported java Is faster than kotlin in terms of compilation time.

  

5.  There is lack of professional workforce because kotlin is still young. Still the number of kotlin -related vacancies are going up.

Conclusion

The advantages of java over kotlin are the advantages which kotlin can overcome in some upcoming years but the advantage of  kotlin over java can't be overcome by java . Since kotlin community is small than java's community that's why it has some drawbacks otherwise Kotlin is the future of Java .

So Java VS Kotlin - Which is better? Well, According to me Kotlin is better.
