Umenzi we Java

I-Java yexesha elidlulileyo elingagqibekanga i-Java 21 (LTS) ngokumiselweyo - iquka iirekhodi, iindidi ezitywiniweyo, i-pattern-matching switch, imisonto ebonakalayo, iibhloko zombhalo, ukuhambelana okudityanisiweyo. Nciphisa kwi-Java 17, 11, okanye 8 nge-target picker. Imveliso nganye idibanisa njenge-is ngee-imports, i-package declaration, kunye ne-Maven / Gradle coordinates ezibizwa ngokuba ngezantsi xa i-libs yangaphandle isetyenziswa. 8 iimfuno zohlobo (Ukwenza / Isiqendu seBoot / I-Concurrent / I-Streams / Classic OOP / Android SDK / Jakarta EE / JUnit test).

Ewe - udidi oluphakathi-ubukhulu lo generatio lubiza ~1,500 iitokeni kwi Qwen 3 Coder model engagqibekanga, ngokukhululekileyo ngaphakathi kwe 6,000 engaziwayo okanye 30,000 ebhalisiweyo-up pool yosuku. Premium Claude Sonnet / GPT-5 efumanekayo nge-generatio ye complex multi-class Spring Boot izimvo apho imodeli ekhululekileyo rhoqo ilahleka umda.

Copilot ($10-19/mo) yi-IDE plugin egqiba ngokuzenzekelayo njengoko ubhala - idityaniswe ngokuqinileyo kodwa ifuna ukubhalisa. Ikheshi ($20/mo) yi-IDE epheleleyo. I-CodeWhisperer ibhekisa kwi-AWS, ikhululekile kubanini bamashishini. Isixhobo sethu sisixhobo se-web generator xa usenza iprototype, kwimeko yokujonga kwakhona kwekhowudi, okanye ufuna udidi lwemveliso-umgangatho we-one-shot ngaphandle kokufakela nantoni na. Siqhagamshelane nathi nge-Copilot - sibhale i-scaffolding, i-Copilot igcwalisa i-loops.

Java 21 (i-LTS yangoku) yeeprojekthi ezintsha - ufumane imisonto ebonakalayo, ukuhambelana kwepateni, ii-records, iindidi ezitshixiwe. Java 17 yeeprojekthi esele kwi-17 (kwaye LTS, ixhaswe ngokubanzi). Java 11 ukuba unikezelo lwakho lutshixiwe kwisitya esidala. Ungayisebenzisi i-Java 8 ngaphandle kokuba ugcina ikhowudi ye-legacy - i-idiomes eninzi yexesha elidlulileyo ayikho apho kwaye i-Oracle ihlaziya intengiso yaphelile ngo-2022 kubasebenzisi abangahlawuliyo.

Ewe — misela uhlobo kwi "Spring Boot" nobunzulu kwi "Fayili-eninzi" (4/4). Imveliso isebenzisa `// === src/main/java/.../Igama.java ===` okubhalwe emantla ephepha ukuhlukanisa iifayile. Iquka @RestController, @Service, @Repository layers, @Valid input DTOs, @ControllerAdvice global error handling, kunye nokufaka umenzi. Ukulandelana kweJackson kuphathwa ngokuzenzekelayo ngee-records njenge-DTOs. I-Spring Boot 3.x (jakarta.* import) ikhutshwa xa injongo >= 17.

Ewe - khetha "Android SDK" uhlobo. Imveliso isebenzisa Umsebenzi / Icandelo / Imodeli yokujonga iipateni zexesha lokuphila, I-LiveData okanye i-StateFlow yezinto ezibonisiweyo, Ukubuyisela umva kuthungelwano. Ii-Coroutines zikhethwa xa i-Kotlin interop ifunyenwe - isixhobo siza kucebisa ukutshintshela kwi-Kotlin generator yethu ye-Android epheleleyo-ye-idiomatic. Musa ukutshixa umsonto omkhulu.

Qwen 3 Ikhowudi iphatha i-typical bounded generics kakuhle (`<T iqhuba i-Comparable<T>>`, i-wildcards, i-PECS). Ii-generics ezinzima kakhulu eziphezulu-ezithandekayo, iintlobo eziphinda-phindayo, okanye uxinzelelo olunzima lokucinga, tshintshela kwi Claude Sonnet okanye GPT-5 kwiqela eliphezulu — inkqubo yabo ye-multi-step ithatha iziganeko zesiphelo imodeli ekhululekileyo ilahlekile.

Ewe - zombini zitshintshela ngaphezulu kweqhosha le Yenza. I-Javadoc emiselweyo ku-ON yohlobo lokwenza (indlela nganye yomphakathi ifumana @ parameter / @ return / @ throws). Uvavanyo lukhubazekile ngokumiselweyo; yenza ukuba lusebenze ukufumana i JUnit 5 + Mockito udidi lovavanyo oluqeqesha indlela emnandi nenye iimeko yomda.

Ewe - tshintshela kwi "Ncamathisela isiqalisi / isiqalo" tab kwaye uncamathisele udweliso lwesiqulathi seefayili seqela lakho, utyikityo lwendlela, okanye unikezelo oluchaziweyo. Imodeli igqiba ubeko lwakho ngokunyanisekileyo ngaphandle kokunika izinto igama kwakhona okanye ukucwangcisa kwakhona ipakethi yakho.

I-Jakarta EE / Isiqalo se Java 3 (isiphelo se Java >= 17) sikhupha `jakarta.*` ukurhweba ngaphakathi. I-Java 2. x isiqalo sendlela okanye iJava 11 egcinwe sikhupha `javax.*`. Khetha isiphelo sakho ngokucokisekileyo - ukuxuba iingxaki ezimbini zokudibanisa abasebenzisi beSiqalo se Java babetha rhoqo.

Khangela yonke imveliso phambi kokubekwa, efanayo njengoko ungenza umphuhlisi ophantsi icela ukutsala. Ikhowudi ihlala ilungile kwaye ilandela i-Oracle iinkokheli, kodwa imodeli ayinazo iimpembelelo zakho zexesha lokuqhuba, imodeli yokhuseleko, okanye ikhowudi epheleleyo yesiseko semeko. Kuba ikhowudi ekhuselekileyo-e sensitive qhuba / ikhowudi / ukhuseleko / uvavanyo kwimveliso, kwaye kuba refactors sebenzisa / ikhowudi / uvavanyo /.

Ewe — UTHENGA kwi /v1/chat/ ngenkqubo efanayo ecela iphepha eliyenzayo. Kulungile kwikhowudi-yokwakha umatshini kwi CI/CD imibhobho okanye i-IDE iinkqubo ezifakiweyo. Ugunyaziso lomthwalo, umyinge omiselweyo. IiDoc kwi /api/.
