In this concept we are trying to know about the two different terms. Both terms are different from each other. Java and Kotlin both are object oriented- programming languages. In this discussion we learn the differences between Java vs Kotlin. When you read this article you surely understand Java vs Kotlin. And you also know the point of difference why they both are necessary and why it’s necessary to know the difference between them. To know this term for making people comfortable to enhance their knowledge. So let’s start the journey to know more about the terms Java vs Kotlin.

WHAT IS JAVA ?
The term java defines that it is a class-based, high-level, object-oriented, that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language.
Java is the most popular, object-oriented and widely used programming language introduced by James Gosling. Using the programming language, we can create a lot of applications like enterprise applications, web-based applications, and cloud-based applications. Usually it is helpful to develop the back-end. Java is most used and the primary choice option for developers when it comes to android app development. Note that Android itself is written in java.
WHY JAVA ?
When we talk about java, why is it ? so they no longer used it only for the officially supported language for Android development, and surely it is the only choice for web programming.
And the reason why is because it is highly scalable, secure, and robust. That’s the reason it is so widely used.
Here we will expalin the major difference between Java vs Kotlin.
EXAMPLE OF JAVA CODE – HelloWorldExample.java
Some pros and cons of Java
Pros –
- Java is more securable.
- It provides vast community support.
- Java memory is managed by the JVM automatically.
Cons –
- Its performance is too poor.
- Its code is Verbose and complex code.
- Syntaxes in Java are large and complex.
WHAT IS KOTLIN ?
Kotlin is similar to Java, an object-oriented programming language. And it is just like Java developed by JetBrains. Kotlin is an open-source, general-purpose, cross-platform,and sterically-typed pragmatic programming language with type inference.
Kotlin is particularly designed to be related with Java and it is also to improve the existing Java models by offering the solutions to API design deficiencies. It is specially designed for Android and JVM. It mostly focuses on clarity, safety, and Interoperability.
Most of the companies like Pinterest, Uber, Netflix, twitter, etc. are moving to Kotlin for android app development. Because it is one the clean, lightweight, concise, data classes, callbacks, and less verbose especially, and getter/setters.
WHY KOTLIN ?
Kotlin is a concise, modern, interoperable, and the safest programming language. It provides a productive way to write a server-side application. Kotlin is also compatible with the Java ecosystem.
EXAMPLE OF KOTLIN CODE – HelloWorld.kt
Some pros and cons of kotlin
Pros –
- Kotlin is easy to maintain.
- Kotlin is interoperable with Java.
- It is more reliable and less buggy.
- It is easily compatible with exciting Java code.
Cons –
- Kotlin Memory consumption is high.
- The speed of compilation kotlin is too slow.
- It has a smaller developer community.
DIFFERENCE BETWEEN JAVA AND KOTLIN
Let us know the difference between both of them, in the following points, we try to make up the head to head comparison between Java vs Kotlin. So let’s see which language won the fight.
PRIMITIVE TYPE –
Java – The primitive types in Java are not objective.
Kotlin – The primary types in Kotlin are objective.
PRODUCT –
Java – Java is a product of oracle corporation.
Kotlin – kotlin is a product of jetBrains.
USES –
Java – Java is basically used to develop stand-alone applications and enterprise applications.
Kotlin – Kotlin is basically used for developing server side applications and for android application development.
FILE EXTENSIONS –
Java – It uses the extensions: .jar(for archived file), .java(for source file), . class(for class file).
Kotlin – It uses the extensions: .ktm(for kotlin module), .kt( for Kotlin source file), .kts(for Kotlin script file).
COMPILATION TIME –
Java – Its compilation time is pretty fast.
Kotlin – Its compilation time is too slow compared to Java.
CODE COMPARISON –
Java – The code line in Java is doubled than Kotin.
Kotlin – The code line in Kotlin reduces to half.
COMMUNITY SUPPORT –
Java – In Java it provides a very large community.
Kotlin – In kotlin it can’t provide as large as Java.
FUNCTIONAL PROGRAMMING –
Java – It is not functional programming.
Kotlin – It is a combination of procedural and functional programming language.
NULL VALUES –
Java – In Java we can assign the null values to the values but we can’t assign null values to an object.
Kotlin – In kotlin we can assign the null values to any of the objects and variables.
DATA CLASSES –
Java – In Java if we need a class that could hold the data only, for this we need a setter method, define getter, constructors, and the other functions.
Kotlin – In Kotlin if we do something similar in Kotlin, we decide the class with the keyboard data. Rest of the getter, creating constructor, and for the setter methods to the fields are done by the compiler.
FINAL THOUGHT –
Finally we can reach the last pont after reading all of the points related to both of the concepts. Now we are able to understand both of the terms. We say after reading these both terms, we can optimise for Kotlin if we are able to develop an android application or we want to develop to do server-side programming.
And if we should go with Java we want to develop the enterprise application or web application or desktop application.
Java is a more complex programming language, that’s why it is easier to learn. Kotlin is mostly clearer, but also more widely applicable and flexible, which makes it too difficult.
