Kotlini Vs Java
Kotlin on suure jõudlusega keeles (poolt väljatöötatud JetBrains), töötab JVM ja kasutab olemasolevaid Java raamatukogud ja tööriistad. On the other hand, Java saab ka koostoimeid Kotlini komponendid sujuvalt. Esmane eesmärk Kotlini on teha see kasulik praktiline reaalses elus projektid, nii et see on välja töötatud alates nullist ja atraktiivseks olemasoleva Java arendajad. Samuti on lihtne õppida võrreldes teiste JVM keeltele nagu Scala. Kuna Java on sügav koostalitlusvõime Kotlini, Java arendajad on rohkem huvitatud õppida ja katsetada seda. Kotlini on tugev kaubandusliku toetuse ning stabiilne ärimudel, Nii et see ei ole tõenäoline, et saada mahajäetud lähiajal. Alates arendaja seisukohast, Kotlini on väga paljulubav ja see toob rohkem võimalusi lähipäevil. Nii saame julgelt ennustada, et Kotlini on järgmine suur asi Java kogukond.
Probleemide Java arendamise küsimustes
JetBrains did not intend to do anything revolutionary with Kotlin. It wanted to provide a useful language that solves existing problems. Kotlini on järgmised eesmärgid, mis aitab lahendada või vältida olemasolevate probleemide Java ja edukamad.
- 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, a 50 read (u.) kood kirjutatud Java võimalik vähendada 2/3 (u.) read Kotlini.
- Prevent null pointer exceptions.
- Provide quick code compilation.
- Reduce learning time for developers by providing documentation and support.
- Kotlini koodi süntaks on lihtne mõista, nii koodi kontroll on lihtne isegi uus tulija.
- Kestus üldkulud on ka madal kui standard raamatukogu on väike ja kompaktne.
Lisaks eespool suured eelised, Kotlini pakub ka palju muud toetust, nagu lihtne koodi muundamise vahel Java ja Kotlini, lihtne IDE integratsiooni, täis silumine, re-faktooring ja profiilide jne. So, kokku, Kotlini on kindlasti kavatse vähendada valu punktid seisvad Java arendajad.
Love Kotlini omadused
Olulisemad aspektid Kotlini on kirjeldatud allpool, mis Java arendajad peaksid armastavad kasutada.
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.
Lihtne õppida ja kasutada Java arendajad
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, näiteks. Also, Kotlin was inspired by Scala and according to many; it looks a lot like Scala. Kood kasutab JVM ja 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.
tahapoole ühilduvad
Kotlin offers backward compatibility for Java versions 6 ja 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 koostalitlusvõime
Kotlini on palju toed suurendada tootlikkust. On väga ühilduma IDES, nii refactoring, silumine, otsimine, üksus katsetamine on väga lihtne teha.
Rakendamisel ja kasutamisel eespool funktsioonid on tõesti huvitav, nii Java arendajad peaksid seda proovida ja maitsta ilu Kotlini. Võib olla, Java arendaja saab teisendada osa oma Java kood Kotlini ja näha, kuidas see toimib. Ükskõik, kuidas me järgime, Kotlini on kindlasti annan teile hea mulje.
Olgem sõlmida
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.
