The world of Android app development can be complicated, but it doesn’t have to be if you stick to one of the most important aspects of app development: language. If you’re an Android developer looking to switch over to Kotlin, or you’re just getting started with programming and haven’t chosen a language yet, this comparison will help you get up to speed.
Let’s take a look at Java vs Kotlin to see which will give your apps the best start in life.
What is Java?
Java is a general-purpose computer programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible. It was originally developed by James Gosling at Sun Microsystems and released in 1995. The original name was Oak but it was renamed to Java, probably because the Java coffee cup logo looked better. Java's syntax largely resembles C++ but has fewer low-level facilities.

Lightweight
Java is a lightweight programming language that compiles to bytecode and runs on any system that has a JVM. This means you can run the same program on Linux, Windows, or OSX without worrying about the underlying operating system. It also includes automatic memory management so developers don't have to worry about memory leaks and lets developers create classes with inheritance, polymorphism, interfaces, threads, among other things.
Java was designed from the start as an object-oriented language so this helps simplify how objects are created in code.
Robust
Java is a robust programming language that is widely used in enterprise-level applications. It can be used to create cross-platform applications, has a large and active community, and is supported by major corporations.
Java has been around since the 1990s and will continue to evolve with new updates from Oracle. Java's syntax consists of keywords, punctuation, identifiers (names), literals (constants), operators, expressions and statements.
Secure
Java is a programming language that can be used to develop Android apps, websites, and more. One of the reasons it has been so popular is that it’s platform-independent and runs on any operating system with a JVM (Java Virtual Machine). This means you can write one program in Java and run it on Windows, Mac OS X, Linux, iOS, or Android with no additional work. It also supports multiple programming paradigms like object-oriented programming and procedural programming.
What is kotlin?
Kotlin is a statically-typed programming language that runs on the Java virtual machine and also can be compiled to JavaScript source code or uses the LLVM compiler infrastructure. The first stable release was announced in February 2016, after being in development since 2010.
Kotlin is a general-purpose programming language designed with JVM and mobile applications in mind. It is fully interoperable with existing Java code, so you don't have to worry about whether your favorite library will be supported or not.

Function types
Kotlin is a statically typed programming language that runs on the JVM, Android, and browser. Kotlin's primary development team is led by JetBrains programmers who were primarily responsible for developing IntelliJ IDEA. The key features of Kotlin include:
– Null safety without exceptions – no runtime overhead – powerful extension functions and properties (e.g., String kotlins)
– type inference in local variables and when returning values from methods or functions. Hire kotlin app developers in India to meet the standard requirements of the Android app development services.
String Templates
Kotlin is a statically typed programming language that runs on the Java Virtual Machine and also can be compiled to JavaScript source code or uses the LLVM compiler infrastructure.. Kotlin was designed to be a pragmatic language, aiming to combine the ease of programming of a high-level language with efficiency.
Default Arguments
Kotlin is a statically-typed programming language that runs on the Java virtual machine and can also be compiled to JavaScript source code. It offers object-oriented programming and a strong focus on null safety. Kotlin has been developed by JetBrains, the same company behind the IDE IntelliJ IDEA. Kotlin is fully interoperable with existing Java code, meaning you can use libraries written in Java without any hassle.
Collections Library
The Kotlin library provides a rich set of tools to manage and manipulate collections. From arrays, to lists, to sets, to maps and more, the Kotlin Collections Library is an excellent starting point for any developer looking to work with collections in their application.
Null Safety
Kotlin's null safety is the most important feature for me. Kotlin distinguishes between references and values. A reference can be null, whereas a value must not be null. So, to get the length of a list in Kotlin, you would do: list.size() instead of len(list). This might seem like a small detail but it goes a long way towards eliminating errors from unhandled nulls that can cause major problems when writing Java programs.
Major Differences between Java and Kotlin
Overview Difference
Java is a programming language created by James Gosling and released in 1995 as a core component of Sun Microsystems' Java platform. It is based on C++, with additions from Objective-C, but not object-oriented. Kotlin was developed by JetBrains and first released in 2011. Kotlin is compatible with the JVM and compiles directly to Java bytecode.
Nullability
Java and Kotlin have different approaches when it comes to handling nullability. In Java, variables are by default non-nullable; but in Kotlin, they're nullable by default. This means that Kotlin will allow you to assign a value of null to any variable while Java won't.
Annotation Processing
Java vs Kotlin Annotation Processing –
One of the major differences between Java and Kotlin is in annotation processing. In Java, annotations are compiled at the time of compilation. They are used for validation, initialization, and for passing parameters. On the other hand, Kotlin does not use annotation processing.
Functional Programming
While there are many differences between Java and Kotlin, one of the most significant is that Java is a strictly object-oriented programming language while Kotlin is a multi-paradigm language.
This means that while Java only supports object-oriented programming, kotlin can also be written in other styles such as procedural or functional programming.
Kotlin and Java are two popular programming languages in the world of software development. Here,we have listed the key differences between these two languages. Kotlin was created by a team at JetBrains as an alternative to Java for writing Android apps. Kotlin app development services are the new trend and Java is more widely used because it's been around longer, but Kotlin is growing in popularity because it provides more flexibility and interoperability with other languages.
