Kotlin Vs Java
Kotlin errendimendu handiko hizkuntza bat da (garatutako JetBrains), JVM exekutatzen eta dauden Java liburutegiak eta tresnak erabiltzen ditu. On the other hand, Java halaber Kotlin osagaiak elkarreragin ahal izango baitituzte. Kotlin helburu nagusia da erabilgarria da praktikoa bizitza errealeko proiektuetarako egiteko, horregatik, duela hutsetik garatu dira eta egindako erakargarria du dauden Java garatzaileei. ere erraza beste aldean JVM oinarritutako Scala bezalako hizkuntza ikasi behar da. Java Kotlin elkarreraginkortasuna sakona du As, Java garatzaileei dira gehiago erakarri ikasteko eta probatzeko. Kotlin merkataritza laguntza sendo eta negozio-eredu egonkorra dauka, Ez da, beraz, litekeena da behar etorkizun hurbil batean abandonatu emateko. sustatzailearen ikuspuntutik, Kotlin oso itxaropentsua da eta aukera gehiago ekarriko ditu datozen egunetan. Beraz, segurtasunez aurreikus dezakegu Kotlin hori hurrengo Java komunitatearentzat gauza handia izango da.
Konpontzeko Java garapenerako gaiak
JetBrains did not intend to do anything revolutionary with Kotlin. It wanted to provide a useful language that solves existing problems. Kotlin honako helburu horrek konpondu edo lehendik gaiak saihesteko Java eta burutzeko hobeto lagunduko du.
- 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, bat 50 lerroak (gutxi gorabehera.) Java idatzitako kodea murriztu daiteke 2/3 (gutxi gorabehera.) Kotlin lerro.
- Prevent null pointer exceptions.
- Provide quick code compilation.
- Reduce learning time for developers by providing documentation and support.
- Kotlin kodea sintaxia erraz ulertzeko, hain kodea berrikuspena erraza da, nahiz eta comer berri baterako.
- Runtime gardenki ere baxua da liburutegi estandarra txiki eta trinkoa da gisa.
Horiez gain abantaila nagusien, Kotlin halaber Java eta Kotlin arteko kode erraza bihurketa bezalako beste euskarri asko eskaintzen, erraza IDE integrazioa, erabateko arazketa, re-factoring eta profilaketa etc. So, Guztira, Kotlin da betiko aurrean Java garatzaileei mina puntu murrizten joan.
Love Kotlin ezaugarri
Kotlin ezaugarri nagusiak deskribatzen dira horren azpitik Java garatzaileei erabiltzea maite behar.
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.
ikasteko eta Java garatzaileei erabiltzeko erraza
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, adibidez. Also, Kotlin was inspired by Scala and according to many; it looks a lot like Scala. Baliteke kodea JVM eta javac erabiltzen du, 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.
atzera bateragarri
Kotlin offers backward compatibility for Java versions 6 eta 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 elkarreragingarritasuna
Kotlin euskarri asko produktibitatea hobetzeko ditu. oso IDEen batekin egingarria da, beraz refactoring, arazketa, bilatzen, Unitate probak oso erraza egin dira.
Ezartzea eta erabiliz Aipatutako ezaugarriak dira benetan interesgarria, beraz, Java garatzaileei eman behar saiatu eta Kotlin edertasuna dastatzeko. Agian, Java developer bere Java kodea zati bihur dezake Kotlin sartu eta ikusi nola burutzen. Whatever modu jarraitu dugu, Kotlin da behin betiko duzu inpresio ona eman joan.
Dezagun ondoriozta
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.
