Android Application Development is a fantastic way to boost the success of your business. However, selecting the right software programming languages is the biggest issue. For a lot of us, it’s obvious that Java is the best, as it is widely used and everyone is praising it. But, following the introduction of Kotlin, the prevailing belief about Java is questioned and developers begin searching for different queries.

To help you choose between Kotlin Vs Java, we will go over several of the major characteristics of each language, so you can decide which you’d like to learn. We will first discuss the two languages in detail.

Kotlin: Overview

Kotlin is a much more recent language than Java and was first introduced in 2016. It’s an open-source programming language that also allows you to compile code into bytecode, and run on the Java Virtual Machine (JVM) which allows it to run with almost every platform. Furthermore, the frameworks and libraries created by Java are also compatible with the ability to be used within the Kotlin project.

Inspired by Java, Kotlin aims to create a better version that is more efficient and simpler to compile and includes the combination of object-oriented programming as well as functional programming.

Java: Overview

Java was introduced in 1995 at Sun Microsystems. Java is an open-source, general-purpose computing language. Being a multiplatform programming language, Java can be used on virtually any computer, device & server. Furthermore, because it is written in the bytecode format, it runs with all Java Virtual Machine (JVM).

Additionally, Java is statically typed and performs type checking as part of the compilation process. In reality, Java’s syntax has similarities with C and C++ however, it has fewer lower-level features.

Kotlin Vs Java: The Comparison

Now that we’ve got some context it is possible to ask how Kotlin’s expansion affects Java. Does it mean Java will go away? The answer isn’t that easy. This topic has many different opinions. To comprehend both sides of the debate we must first examine the differences between Kotlin Vs Java.

Extension Functions: Kotlin Vs Java

Contrary to Java, Kotlin allows the developer to expand the capabilities of classes, without needing to inherit from the classes. To enable the extension function in Kotlin, developers need to precede the title of the class with the title of the program that was created with a ‘.’ notation.

In Java, to expand the capabilities of a class, one needs to create a new class, and then inherit the functions of the class it is derived from. This means that the extension function isn’t accessible.

Smart Casts:  Kotlin Vs Java

When it comes to casting, the compiler of Kotlin is smart. Many times, it ain’t necessary to make explicit casting operators in Kotlin. However, in contrast to Java, Kotlin has “is-checks” for unchangeable values, & automatically inserts casts when needed.

Static Members:  Kotlin Vs Java

Kotlin does not have a provision for static members. However, in the Java programming language, the term static indicates that the member is related to a specific type rather than an instance belonging to that type. This simply means that only an instance of this static element is made and shared among each instance in the class.

Null Safety:  Kotlin Vs Java

NullPointerException (NPE) is one of the main drawbacks of Java, and the only possible reason for NPE is an explicit call to throw NullPointerException. There are data inconsistencies caused by initialization, or other issues that are caused through the external Java code. Kotlin avoids NullPointerException. Kotlin will fail at the time of compilation if it is notified that a NullPointerException could be in the process.

Code Conciseness:  Kotlin Vs Java

Comparing a Java class to a comparable Kotlin class shows the simplicity of Kotlin code. To perform the same function similar to what the Java class does, but with less code Java class, the Kotlin class will require less code.

For instance, one section where Kotlin could drastically reduce the number of boilerplate codes is findViewById. Kotlin Android Application Development Extensions allow the import of references to View within an Activity’s file. This lets you work with the View in the same way as it were an element of the Activity.

Implicit Conversions:  Kotlin Vs Java

Kotlin is not able to offer support for implicit widening conversions. So, smaller types cannot be converted into larger types. To get around this issue, Kotlin developers must carry out an explicit conversion to accomplish the type of conversion desired. However, Java supports implicit conversions so developers don’t need to make explicit conversions.

Higher-Order Functions & Lambdas:  Kotlin Vs Java

A higher-order function uses functions as parameters or returns functions. Additionally, Kotlin functions are first-class. This means they can be saved in structures of data as well as variables and can be used as arguments for and returned from higher-order functions.

It is simply that functions are able to be used in any way that is feasible for functions. Being a statically typed system, Kotlin uses functions of various types to represent functions. Additionally, it has an array of language concepts, including Lambda Expressions.

Type Inference:  Kotlin Vs Java

In Kotlin, it is an advantage that all variables need not be explicitly defined. However, if you wish to specify a type of data clearly between Kotlin and Java Android, you can also do so.

Functional Programming:  Kotlin Vs Java

The primary thing to consider in Kotlin’s comparison to Java efficiency is the fact that Kotlin is a functional language. Essentially, Kotlin consists of many helpful methods, such as lambda expressions of higher-order operators overloading, lazy evaluation operator overloading, and a lot more. Functional programming makes Kotlin more efficient when it comes down to collections.

Last Say

This blog provides an overview of the differences between Kotlin Vs Java. We hope that you will be able to understand the difference between Java as well as Kotlin languages after having read this Java and Kotlin article. According to our opinion, we could use Kotlin for Android Application Development without worrying about the process of compilation even though Java offers a few benefits over Kotlin.
