Kotlin Vs Java
Kotlin is 'n hoë werkverrigting taal (ontwikkel deur JetBrains), loop op die JVM en gebruik bestaande Java biblioteke en gereedskap. On the other hand, Java kan ook in wisselwerking met Kotlin komponente moeiteloos. Die primêre doel van Kotlin is om dit te nuttig vir praktiese werklike lewe projekte, so dit is ontwikkel van nuuts en aantreklik gemaak om die bestaande Java-ontwikkelaars. Dit is ook maklik om te leer in vergelyking met die ander JVM gebaseer tale soos Scala. As Java het 'n diep interoperabiliteit met Kotlin, Java-ontwikkelaars is meer aangetrokke tot leer en toets dit. Kotlin het 'n sterk kommersiële ondersteuning en stabiele sakemodel, so dit sal nie geneig om te kry verlate in die nabye toekoms. Uit die oogpunt van ontwikkelaar se, Kotlin is baie belowend en dit sal meer geleenthede in die komende dae te bring. So kan ons veilig voorspel dat Kotlin die volgende groot ding vir die Java gemeenskap sal wees.
Die oplossing van Java ontwikkelingskwessies
JetBrains did not intend to do anything revolutionary with Kotlin. It wanted to provide a useful language that solves existing problems. Kotlin het die volgende doelwitte wat jou sal help om op te los of bestaande probleme in Java te vermy en beter te presteer.
- Provide an intuitive language that can infer from codes written by developers and do a lot of work on behalf of developers.
- Improve productivity by reducing the effort needed to write code. For example, 'n 50 lyne (ongeveer.) kode geskryf in Java kan verminder word tot 2/3 (ongeveer.) lyne in Kotlin.
- Prevent null pointer exceptions.
- Provide quick code compilation.
- Reduce learning time for developers by providing documentation and support.
- Kotlin kode sintaksis is maklik om te verstaan, sodat die kode resensie is eenvoudig, selfs vir 'n nuwe hoek.
- Runtime oorhoofse is ook laag as die standaard biblioteek is klein en kompak.
Afgesien van die bogenoemde groot voordele, Kotlin bied ook baie ander stutte soos maklike kode omskakeling tussen Java en Kotlin, maklik IO integrasie, volle ontfouting, Re-faktor en profilering ens. So, in totaal, Kotlin gaan beslis die pyn punte in die gesig gestaar deur die Java-ontwikkelaars te verminder.
Wees lief vir Kotlin funksies
Die belangrikste kenmerke van Kotlin beskryf onder watter Java-ontwikkelaars moet lief om te gebruik.
No more null pointer exceptions
This is probably the most important feature. The null pointer exception is one of the most dreaded, unsolved issues developers face. Kotlin’s type system does not compile code that assigns or returns null. See the below example.
val name: String = null // tries to assign null, won’t compile
stephen getName() : String = null // tries to return null, won’t compile
Since every method call on a nullable type can potentially cause a null pointer exception, the Kotlin compiler forces the developer to use the Elvis operator whenever the call result is assigned to a non-null type.
Lesser coding
Kotlin compiler can infer or understand from the code written by a developer and can develop or write the remaining code unlike in Java. Java requires the developer to explicitly write everything which consumes a lot of time and effort. Kotlin saves effort and time and improves productivity. For example, Kotlin compiler can infer types in variable declarations as well as compiler-generated getters/setters/equals/hashCode. On the other hand, the Java compiler does not infer as much and requires the developer to explicitly write code.
Maklik om te leer en te gebruik vir Java-ontwikkelaars
Since Kotlin is nothing revolutionary, any software developer can learn and start to use it especially the Java and Scala developers. The main reason is Kotlin is dependent on Java in a lot of ways and extensively uses the Java library, byvoorbeeld. Also, Kotlin was inspired by Scala and according to many; it looks a lot like Scala. Die kode maak gebruik van die JVM en die Javac, the primary Java compiler. The learning curve for Java developers is not steep and they can leverage the Kotlin documentation and get started quickly with coding.
backwards compatible
Kotlin offers backward compatibility for Java versions 6 en 7. It states in its blog that over the next few releases, it is going to speed up development workflow, reduce the size of the runtime library and provide more tooling support. Kotlin will be introducing a feature known as incremental compilation in its Gradle build plug-in. This will enable Kotlin to compile and build only the changes in the code and not the whole code over. This is going to save a lot of time.
IDE interoperabiliteit
Kotlin het 'n baie steun vir die verbetering van produktiwiteit. Dit is hoogs participating met die Ides, sodat refactoring, ontfouting, soek, eenheid toets is baie maklik om te presteer.
Implementering en gebruik van die bogenoemde kenmerke is baie interessant, sodat die Java-ontwikkelaars moet dit 'n probeer en proe die skoonheid van Kotlin. Kan wees, 'n Java ontwikkelaar kan deel van sy Java-kode te omskep in Kotlin en sien hoe dit presteer. Wat ook al manier waarop ons volg, Kotlin is beslis gaan jou 'n goeie indruk te gee.
Kom ons sluit
Its evolving state notwithstanding, Kotlin already looks like a tool that is going to improve productivity significantly. Many developers are positive about Kotlin enabling them to achieve a breakthrough in their productivity. A discussion on Hacker News website which hosts a discussion on Kotlin reveals that Kotlin solves many Java pain points without really reinventing how coding should be done. What are the challenges ahead? To find huge acceptance, it needs to be able to impress firms like Google which is a huge Java user and has been working on other alternatives to Java. It will be interesting to watch how Kotlin goes about its plans and how it faces the challenges ahead.
