Soosaarka Java

Modern idiomatic Java oo loogu talagalay Java 21 (LTS) si default ah - waxaa ku jira diiwaanada, fasallada la xidhiidha, isbeddelka isku-dhafka, xirmooyinka dhabta ah, blokada qoraalka, isku-dhafka dhismaha. Jadwalka hoos u dhaca ilaa Java 17, 11, ama 8 iyada oo loo marayo doorbidka taraafikada. Soosaar kasta oo soo saar ah ayaa lagu soo bandhigaa sida ay tahay soo dejinta, bayaanka pakiga, iyo Maven / Gradle coordinates oo lagu magacaabo faallooyin marka libs-ka dibadda la isticmaalo. 8 qaababka hore (soosaar / Spring Boot / isku-dhafan / Streams / Classic OOP / Android SDK / Jakarta EE / JUnit imtixaanka).

Haa — mid dhexdhexaad ah-sized fasalka dhalasho ku kacaysaa ~ 1,500 calaamadaha ku default Qwen 3 Coder tusaale, raaxo leh gudaha 2,500 aan la aqoon ama 10,000 signed-up maalin kasta. Premium Claude Sonnet / GPT-5 oo ku jira per-dhalaal u fudud multi-qaab Spring Boot jawaabaha halkaas oo tusaale bilaash ah marar badan ku fashilantay xaddidaad.

Copilot ($10-19/mo) waa IDE plugin in autocompletes sida aad daabacdo — si adag u midoobay laakiin u baahan yahay subscription. Cursor ($20/mo) waa IDE buuxa. CodeWhisperer waa AWS-focused, bilaash ah oo loogu talagalay dadka. qalabkeena waa web generator for marka aad prototyping, in code-eegista context, ama doonayaan mid-shot wax soo saarka-tayada fasalka aan waxba ku rakibi.

Java 21 (LTS hadda jira) ee mashaariicda cusub - waxaad ka heli doontaan xirmooyinka dhabta ah, isku-dhafka qaabka, diiwaanada, fasalada la xidhay. Java 17 ee mashruucyada horeyba u jira 17 (LTS, sidoo kale, si ballaaran loo taageeray). Java 11 haddii bixintaada loo xiro baabuur hore. Ka fogaada Java 8 haddii kale ma aha in la ilaaliyo koodka dhaxalka - afaf badan oo casri ah ma jiraan oo Oracle ayaa dib u cusbooneysiiyay 2022 ee isticmaalayaasha aan bixinin.

Haa — qaabka loo dhigay "Spring Boot" iyo qoto dheer in "Multi-file" (4/4). Wax soo saarka isticmaalaa `// === src / main / java /... / Name.java ===` madaxa in faylasha kala sooca. Waxaa ka mid ah @RestController, @Service, @Repository darajooyinka, @Valid input DTOs, @ControllerAdvice khaladka guud ee xalinta, iyo injiis dhismaha. Jackson serialization waa si otomaatig ah loo xallin karaa diiwaanada sida DTOs. Spring Boot 3.x (jakarta.* dhoofinta) waa la soo saaray marka la rabo> = 17.

Haa - dooro qaabka "Android SDK". Soosaarka wuxuu isticmaalaa qaababka Activity / Fragment / ViewModel ee nolosha, LiveData ama StateFlow oo loogu talagalay observables, Retrofit for network. Coroutines waa la doorbidayaa marka la ogaado Kotlin interop - qalabkani wuxuu soo jeedin doonaa inuu u dhaqaaqo soosaarka Kotlin ee Android-ka oo dhan.

Qwen 3 Coder xakamayn kartaa caadiga ah bounded generics wanaagsan (`<T kordhisa Comparable<T>>`, wildcards, PECS). For aad u adag oo ka sarreeya-qaab generics, noocyada soo noqnoqda, ama xoog badan ee iftiinka trickery, u beddelaan Claude Sonnet ama GPT-5 in kooxda premium - iyaga oo multi-tallaabo talooyin qabtaa cidhibta kiisas oo ah qaabka bilaashka ah misses.

Haa — labadaba waa toggles kor ku button soo saarka. Javadoc defaults ON qaabka wax soo saarka (sida dadweynaha oo dhan ka helaa @param / @return / @throws). Imtixaanku waa off by default; u beddelaan si aad u hesho JUnit 5 + Mockito imtixaan fasalka tababarka jidka farxad iyo mid ka mid ah cidhibta kiis.

Haa — u dhaqaaqo "Paste starter / stub" tab iyo paste aad fasalka qaabka, habka saxiixyada, ama hirgelinta qayb ka mid ah. Muuqaalka dhamaystira dhismaha aad si daacad ah aan waxba loo magacaabin ama dib u habeynta paketka.

For Jakarta EE / Spring Boot 3 (target Java> = 17) waxaan soo saar `jakarta.*` dhoofinta. For Spring Boot 2.x wadooyinka ama dhaxal Java 11 waxaan soo saar `javax.*`. Pick your target si taxadar leh — isku darka labada sababaha qaladaadka soo ururiyaan Spring Boot isticmaalayaal ku dhuftay badanaa.

Codsiga waa caadi ahaan sax ah oo raacaya heshiisyada Oracle, laakiin qaabka ma laha xaddidaadyada runtime, qaabka amniga, ama context codebase buuxa. Si aad u code amniga-qasab ah u socdaan / code / amniga / xisaabinta ku saabsan natiijada, iyo refactors isticmaalka / code / review /.
