Java vs Kotlin: Which One Is The Best Language For Android

If you are beginning to program in Android, it is frequent that the language we use Java. What’s more, Java is used all over. Now Kotlin arrives, which brings extensive enhancements. We have chosen to set up this blog of Java vs Kotlin. Which language is the best?

To understand the contrasts between Kotlin vs. Java, most importantly, we choose to discuss a little about every language. We will begin with Java, and you will know its points of interest, weaknesses, and furthermore what we can do with this language. 

Next, we will discuss Kotlin, with the goal that this language serves, favorable circumstances, disservices, and what we can make? At last, it will be incredible to understand the critical contrasts of Java vs Kotlin.

Java introduction:

Java is an object-arranged programming language that was introduced by Sun Microsystems. It appeared 23 years back, and with other prominent languages like Scala and Groovy, it has stayed in the essential languages in Android application improvement. 

Since its beginning, Java android application advancement is widely utilized in the structuring of server applications, Android applications, web applications, inserted frameworks, and sites. The more significant part of the Java components is available as open-source. Java fame is most in money related programming advancement.

What are the benefits of Java?

Here are the benefits of the Java language: 

  • Java is a cross-platform programming language that can operate on practically any device, server, or operating system.
  • Its coding is solid, and java instructions won’t mess with memory or data from other OS programmes.
  • Because java is object-oriented, designing modular applications and reusing pieces that contribute to that application’s robustness is simple.
  • It’s ready to use, and you’ll get a lot of ready-to-use third-party code with java. 
  • When kotlin and java are compared to the performance of other languages, java is easier to use, build, debug, and deploy.
  • Java is an open-source language that provides security because many of its libraries are controlled by reputable companies such as Google, Apache, and others.

What are the difficulties of Java’s language?

Some of java’s challenges are as follows:

  • Java’s syntax can be a little difficult or clunky when compared to other languages like C++ or python.
  • Accessing content that is incompatible with the device or equipment you’re using java on is impossible.
  • Getting your hands on the most recent java developments for mobile development isn’t easy.
  • There are times when java gets in the way of the development of android APIs. 
  • For java, test-driven development means writing more code, which increases the chances of programming errors and difficulties.
  • Java is a little slower than other programming languages and consumes a lot of system memory.

What is the application of java?

  • Spotify
  • Twitter 
  • cash is a mobile application that allows you to send money.
  • Signal
  • Amaze File manager.

Java limitations:

  • Its restrictions can cause glitches with Android API plan; 
  • Because of more codes in Java, the possibility of mistakes and bugs increments extensively; 
  • Contrasted with different languages, Java is a little slow and needs a large amount of memory.

Kotlin introduction

Kotlin is a universally useful programming language that includes java virtual machine, Android, JavaScript, and Native. JetBrains create it as an open-source stage under the Apache 2.0 permit. 

If you are asking ‘why to use Kotlin” for the Android studio programming language; this is because the engineer can send Kotlin as an object-arranged programming and useful programming. Kotlin utilizes LLVM compiler innovation to gather Kotlin codes into binaries for CPU designs and working frameworks like iOS, Windows, Linux, and Mac. 

Probably the best thing about this language is that it joins both object-situated and useful programming characteristics.

Coming up next are the significant Java IDEs aid that comes packed with Kotlin for Android designers: 

  • IntelliJ IDEA (the brainchild of JetBrains) 
  • Android Studio 
  • Obscuration 
  • NetBeans 

Kotlin can be utilized for the improvement of most types of applications; at that point, it very well may be from the server-side, customer-side web, or Android. 

What are the benefits of using kotlin?

  • App deployment in kotlin is light, quick to compile, and prevents apps from expanding in size.
  • In comparison to java, each chink of code produced in kotlin is significantly smaller since it is less verbose, and less code means fewer issues.
  • Kotlin converts your code to bytecode, which you can run on the java virtual machine (JVM). as a result, all java libraries and frameworks are transferred to kotlin project and run there.
  • The Kotlin script aids in the configuration of android studio projects for auto-completion aids and reduces compile-time error detection.
  • It is immune to null pointer exceptions (the billion-dollar mistake).
  • For web development, kotlin has coroutines as well as javascript interoperability.

What are the difficulties of the kotlin language?

  • Because Kotlin is not as well-known as other well-established languages like Java, the developer community is small.
  • Kotlin matches weak patterns, making the first few lines of code a little challenging to read and understand.
  • Because kotlin is a newer language than Java, it has a limited support community. In addition, there are fewer libraries, blog posts, and tutorials. 
  • Kotlin has a steep learning curve, and due to the language’s tight syntax, switching teams to it may be problematic.
  • There are only a few kotlin developers on the market. As a result, finding a knowledgeable mentor can be challenging.

What does kotlin have to do with anything?

  • Pinterest
  • Trello
  • Evernote
  • Shadowsocks for twitter twidere

Kotlin limitations

  • A precarious expectation to absorb information for groups who wish to travel totally to Kotlin; 
  • Aggregation speed is delayed when contrasted with Java; 
  • Finding an expert Kotlin designer is as yet an irregularity; 
  • Android Studio’s accumulation and auto-complete run slower whenever compared with Java ventures.

Java vs Kotlin

1 Market circumstance

The impact of Java on the modern world is vast, which is sponsored by the respectable Tiobe Index. Starting in July 2019, Java has kept up its main spot contrasted with July 2018. Kotlin, however still a youthful language, has made it to the best 50 of the rankings, setting down at number 43. 

Google I/O 2017 gathering was set apart by the advancement of Kotlin to the positions of its “top of the line” programming languages for Android application improvement.

It joined the great old Java and C++. The declaration has energized up the interest over Kotlin, causing the astounding development in its popularity.

2 Progress

  Firstly, Kotlin was planned in such a way, that it could without much of a stretch interoperable with Java. Therefore, the designers can interpret java codes into Kotlin and vice versa, that too, without the need to change the operability. 

Kotlin is the new language, offers some extra characteristics that make Kotlin a favored pick over Java. A client ca n’t separate between the two since codes of both the programming languages are assembled to JVM bytecode.  

3 Smart casts 

In Java, We have to check the kind of factors and cast them by our activity. 

In Kotlin, smart casts will deal with these casting checks with keywords “is-checks”, which will check for permanent qualities and performs hinted casting.

4 Null safety

In Java, NullPointerExceptions causes tremendous dissatisfaction for engineers. It enables clients to relegate invalid to any factors yet while getting to an item reference having invalid worth raises an invalid pointer particular case which the client needs to deal with. 

In Kotlin, By default, a wide range of factors are non-invalid capable (for example we can’t dole out invalid qualities to factors/objects). If we attempt to appoint or return invalid classes, Kotlin code will fizzle during the arranged time. If we genuinely need a variable to have an invalid worth, we can proclaim as pursues: 

esteem num: Int? = null

5 Type inference

In Java, we have to indicate a kind of every factor expressly while announcing. 

In Kotlin, we don’t have to indicate the kind of every factor unequivocally dependent on the task it will deal with. If we need to state expressly, we can do it.

6 Useful programming

Java doesn’t have practical programming support until Java 8; however, while creating Android applications, it supports the main subset of Java 8 characteristics. 

Kotlin is a blend of procedural and useful programming language which comprises numerous helpful strategies, for example, lambda, administrator over-burdening, higher-request capacities, and apathetic assessment, and so on.

7 Expansion functions

In Java, If we need to expand the use of the existing class, we have to take another class and acquire the parent class. So Extension capacities are not accessible in Java.    

Kotlin gives designers the capacity to expand a current class with new usefulness. We can make broaden works by prefixing the name of a class to name the new capacity.

 8 No checked exceptions 

In Java, We have checked special case support which causes designers to proclaim and get the exemption which at last prompts strong code with excellent mistake handling.    

In Kotlin, we don’t have checked special cases. So designers don’t have to proclaim or get special cases, which have benefits and limitations.

9 Information classes   

In Java, assume we require to have a class that needs to hold information yet nothing else. For this we have to characterize constructors, factors to store information, getter and setter techniques, hashcode(), toString(), and equivalents() functions    

In Kotlin, If we require to have classes that need to hold information. We can announce a class with keywords “information” in the class definition then the compiler will deal with the majority of this work. For example, making constructors, getter, setter strategies for various fields.

What is the key difference between Java vs. kotlin?

Both are popular options on the market; here are some key differences to consider:

  • The brilliant cast is supported in kotlin, which identifies immutable types and conducts implicit casting via a compiler, whereas we must identify and perform casting in Java.
  • Type inference is supported in Kotlin, which means we don’t have to indicate the data type of variables directly, whereas we do in Java.
  • In kotlin, we don’t have checked exceptions, which is a drawback because it leads to error-prone code, but java has, which allows us to manage errors.
  • Although Java compiles 15-20% faster than Kotlin, in terms of incremental build compilation, Kotlin takes the same amount of time as Java.
  • We can’t assign null values to variables or return values in kotlin; if we want to, we can declare a variable with a specific syntax; in Java, we can assign null values, but accessing objects pointing to null values raises an exception.
  • Regardless of the differences between Java vs. Kotlin, they are interchangeable. We can refer to kotlin code as java code and java code as kotlin code. As a result, we can use both Java and Kotlin classes in the same project and have no problems compiling them. We were unable to determine if the class was written in Java or Kotlin after compilation. 

Does Kotlin take the place of java language? 

The response to this inquiry relies upon the different assessments of versatile application developers. Since Java is an outstanding programming language having different open-source instruments and libraries to help developers.

No language accompanies perfectness. Java itself can be difficult for some. For this, Kotlin has come, which tends to regular programming stress with its successful arrangements and furthermore improves the Java system. 

We currently realize that Kotlin has turned into an increasingly steady and consistent improvement choice for Android Studio. Some Android engineers appear to accept that Kotlin will remove Java for versatile application advancement sooner rather than later.  

In Kotlin vs Java conversation, it is Kotlin which is spotless, naturally lightweight and less repetitive as far as data classes, getters/setters and writing callbacks. It is explicitly made for improving the current Java models utilizing answers for API structure lacks. 

Thus, we can say that Kotlin isn’t a substitution for Java; it’s an improvement.

Java vs. kotlin: which one is better?

  • When all of Java’s flaws are considered, particularly the problem with null pointer exceptions, kotlin appears to be the superior language.
  • Although, because the android OS is based on java, it is still an important language for any android app development.
  • If you want to ensure that your android app development services are future-proof, you should engage kotlin developers.

Quick Links


At last, its a review of the difference between Java vs Kotlin. From this, you will have a superior understanding of both Java and Kotlin language, after perusing this Java vs Kotlin article. In my view, we can continue with Kotlin for Android application advancement without stressing over the accumulation time even though Java has few favorable circumstances over Kotlin.
