Java vs Kotlin

Java Assignment Help experts will explain you Java vs Kotlin in a better way. If you are a mobile app developer, Java is probably your language for building Android apps. But new languages are popping up everywhere that might challenge Java’s dominance in the Android world. One of them is Kotlin, a relatively new programming language, already announced by Google as a “first-class” language supported on Android.


Kotlin v1.0 was published only on 15, February 2016, the history of this programming language defines back to 2011. JetBrains founded Kotlin for their practical needs.

Java to Kotlin story

The company had 70% of its outputs build on Java but began to understand its shortcomings – mainly unnecessary wordiness. They wanted a programming language that would be Java-compatible since rewriting everything into a new programming language appeared as a no-go option. Everybody started experimenting with Scala but were not fulfilled. That is when the concept of a new programming language, Kotlin, was born.


Null

Safety

As mentioned earlier, Kotlin avoids NullPointerException. Whenever NullPointerException can be thrown, The Kotlin fails at compile-time.

Difference Between Java vs Kotlin

Data

Classes

Kotlin consists of boilerplate data classes, hashcodes, tostring, getters/setters and much more such as boilerplates lead to autogeneration.


/* Java programming */ class Book { private String title; private Author author; public String getTitle() { return title; }

Example of Java vs Kotlin

public void setTitle(String title) { this.title = title; } public Author getAuthor() { return author; } public void setAuthor(Author author) { this.author = author; } }


But the above one class in Kotlin may be briefly defined in a row /* kotlin programming */

Example of Java vs Kotlin

data class Book(var title: String, var author: Author) It will also allow us to easily make copies of data classes with the help of copy() val book = Book(“Kotlin”, “JetBrains”) val copy = book.copy()


Extension Functions Kotlin allows us to expand the functionality of existing classes without having inherited from them. That is to say, Kotlin provides the ability to extend a class with new functionality without inheriting from the class.

Java vs Kotlin

This is done by expansion works. To declare an extension function, we have to prefix its name with a receiver type, that is. The type is being increased. Functional Programming The main important thing is that Kotlin is a functional programming language. Originally Kotlin includes several useful methods, including high-order tasks, longrate expressions, operator overloading, lazy valuations, operator overloading and much more.
