Kotlin vs Java, Which One is the Best?

There is no comparison between Kotlin and Java because one is best than another, so we could not decide which is best. Because Kotlin is a vibrant, advanced software programming language. It is simple to learn, particularly if you are already familiar with Java (it is completely compatible with Java).

Kotlin is used to create Android applications, web server applications, and many other things.

Java is a well-known software program. It is used to create smartphone applications, web applications, desktop applications, games, and many other things.

It depends, as with everything, so we'll take a glance at the main differences here. But first, consider why someone could ask this question in the first place.

What do you Mean by Kotlin Programming Language?

Kotlin is a newish software program language that was first released in 2011 by JetBrains, a software company best known for its well-liked IntelliJ IDEA Java Integrated Development Environment(IDE).

Kotlin is a new programming language prompted by it, but it's an advanced version with many more features. When tried compared to other programming, it is modern, simple, and has very few procedures and guidelines.

Designers must understand basic programming skills and structuring to employ this language to create Android applications.


We described below what a Kotlin programming language looks like it.

fun main() { println("Hello World") }

What is Java Programming Language?

James Gosling developed Java in the early 1990s while working at Sun Microsystems, which Oracle later purchased.

Java has become the most widely used and adopted software program. It is simple, object-oriented, and designed to have as few operational interconnections as potential.

Java is a powerful language that helps guide the development of various custom application operating systems as well as new programming languages. Its features are among the reasons for its outstanding performance.


It is a simple program that is described below how a Java program looks.

public class Main { public static void main(String[] args) { System. out.println("Hello World"); } }

Kotlin vs Java

That is what we will discuss here. What are the important factors that differentiate Kotlin and Java?

Java is an Oracle Corporation product. Kotlin is a JetBrains product.
Java employs the following file extensions: .java, .class, and .jar, etc. Kotlin uses the following file extensions: .kt, .kts, and .ktm, etc.
Java is employed to create both standalone apps and business requirements. Kotlin is employed to create server-side applications as well as Android applications.
Java has a large user community. Kotlin user base is not as large as that of Java.
Java isn't a functional programming language. Kotlin is a fully functioning and procedural language of programming hybrid.
Java programming code's compilation time is relatively short. Kotlin Its compilation time is slower than that of Java.
Info classes in Kotlin are simple to create. Java programmers build a large number of elements to build classes.
In Java, Primitive types are not objects. In Kotlin, Primitive types are objects.
The try-catch block is how we handle checked exceptions in Java. Here in Kotlin you do not need to catch or declare any exceptions.
In Java, mandatorily you need to specify the data type, explicitly. In Kotlin, it is not mandatorily you need to specify the type of variable explicitly.
Ternary operator is available in Java. Ternary operator is not available in Kotlin.
Java is not a functional programming. Kotlin is a combination of functional and procedural programming language.


From the above discussion, you will be clear that if you are interested in creating an android application or a backend programming language, then Kotlin is good.

On the other hand, if you want to create web applications, enterprise applications, and desktop applications then Java is the best choice.

Java is a tried-and-true programming language that has been used for many years, is simple to learn, and boasts a large developer community that can assist. Kotlin is a completely new language with less support, but its numerous advantages mean that more developers are starting to employ it for programming. Selecting the best one for your needs is a matter of personal choice.
