- 4. Introduction • Kotlin is a statically-typed programming language • It is jvm targeted language • It support object oriented programing and functional programing feature • It can also can be compiled to JavaScript source code • Its primary development is from a team of JetBrains
- 5. History… In July 2011 JetBrains Start Project Kotlin, a new language for the JVM, which had been under development for a year. JetBrains hopes that the new language will drive IntelliJ IDEA sales. Kotlin v1.0 was released on February 15, 2016. In may 2017 Google I/O Declared as the First class language for android development
- 6. Features of Kotlin programming language • Kotlin is open source. • Full Java Interoperability. • Kotlin compiles to JVM bytecode or JS. • Null Safety in Kotlin. • Kotlin wants you to write less code. • Higher order function
- 7. Basic syntax PACKAGE:- Package specification should we at the top of the application similar to java Example- package Bu.Iet; import java.util;//import util package Defining local variables Example- var a:Int=12//immediate assignment var a=123;//type inference
- 8. Difference Between Kotlin and java No Semicolons // Java System.out.println("Hello world!); // Kotlin println("Hello world!")
- 9. No 'new' // Java Boa a = new Boa(); // Kotlin val a = Boa()
- 10. No Checked Exceptions • // Java code often looks like this • Try • { • Connection con=DriverManager.getConnection()//this sta throw an checked exception • } catch(SqlException r) • { • } • // Kotlin has no checked exception
- 11. Type Inference // Java Int a = 1; String b = “sachin"; Program p; // Kotlin var a = 1 var b = “sachin" var p: Program
- 12. Size of Code • // Java • class Person • { • String firstName; Person(String firstName) { this.firstName = firstName; • } • } • // Kotlin class with primary constructor • class Person(firstName: String)
- 13. Data Classes • // Java • To hold the data we must make simple classes with getter and setter method in data • // Kotlin • In kotlin they provide the concept od data classes to hold the data • To define an data class in kotlin we use the keyword data before the class keyword • data class Student(val name: String,val age: int)
