«Ndaqhekeza nentombi yam umdwelisi wenkqubo. Akayazi iJava »Ndasiva isiqhulo okokuqala kwinkqubo yerediyo ejolise kuluntu ngokubanzi. Oko kubonisa ukuba Ukuthandwa kolu lwimi lweminyaka engama-25 ubudala kudlula indawo yesayensi yekhompyuter.
Igama Java lisetyenziswa kakhulu ukubhekisa kulo iqonga leJava, oko kukuthi, iseti yezixhobo zokuphuhliswa okukhawulezayo kwezicelo zeplatform ezininzi, kunye nolwimi lwenkqubo ngokubanzi yenziwe yinkampani yeLanga yokuphuhlisa iinkqubo zeli qonga.
Umahluko weJava ngokubhekisele kwezinye iilwimi zenkqubo yile Yenzelwe ukuba ikhowudi ebhaliweyo ibaleke kuyo nayiphi na inkqubo enokuqhutywa ngumatshini oqinisekileyo IJava (JVM).
Ngokwenyani. IJava ayizalwanga ukuba isetyenziswe kwinkqubo yekhompyuter. Kwiminyaka engama-90 ishishini losasazo lalibheja kumabonwakude osebenzisanayo kwaye abaphuhlisi babecinga ukuba kuya kuba luncedo ekusetyenzisweni kwidesekhowudi kwaye yintoni eza kuthi kamva yaziwe ngokuba ziithelevishini ezihlakaniphile. Nangona kunjalo, iinkampani zikamabonakude wentambo zazingenamdla. FNgabaphuhlisi be-Intanethi ababone ukubanakho kunye neNetscape, isikhangeli sokuqala, sayifaka.
IJava ijika i-25. Imbali encinci
Ukuqala kweprojekthi kufuneka kulandelwe ukuya ku-1991 xa uJU-Ames Gosling, uMike Sheridan, kunye noPatrick Naughton babumba iqela elibizwa ngokuba liGreen kwiqela leSun Microsystem. (Iqela eliluhlaza). Iinjongo zabo zazinomdla, bafuna ukwenza ulwimi lwenkqubo
Ilula, irobust, iyaphatheka, iqonga elizimeleyo, likhuselekile, ukusebenza okuphezulu, imisonto emininzi, uyilo olungathathi hlangothi, ukujolisa kwinto, ukutolikwa kunye namandla.
Ekuqaleni ulwimi lwamva lwalubizwa ngokuba yi-Greentalk kwaye iifayile zalo zazinolwandiso. I-Oak ithathwa njengophawu lwamandla kwaye ikhethwe njengomthi wesizwe kumazwe amaninzi anjenge France, Germany, Romania kunye ne United States. Kwakhona, yayiluphawu lwentengiso olubhalisiweyo lwenye inkampani.
Kutheni le nto Java ephela sele ebizwa?
Xa abaphuhlisi bafumanisa ukuba abanakukwazi ukuyibiza ngokuba yi-Oak, baxuba amanye amagamas. Babefuna igama elibonisa intsingiselo yolu lwimi lutsha: inguquko, amandla, uyaphila, upholile, wahlukile, kulula ukuba upele, kwaye kuyonwabisa ukutsho.
Bavavanya ukuguqula amandla, ukuguqula, iSilk, iJolt kunye neDNA. Okokugqibela, bakhetha igama elize neGosling ngaphezulu kwekofu. UJI-ava ayisosifinyezo, ibhekisa kwisiqithi sase-Indonesia apho kuveliswa khona ezinye zeentlobo ezilungileyo zokufakwa.
Ngo-1995 inguqulo yokuqala yesilingo sekhiti yonjiniyela yakhutshwa Kwaye, kwakuloo nyaka, iphephancwadi i-TIme labiza enye yeemveliso ezilishumi zonyaka. Namhlanje ulwimi isetyenziselwe ukwenza i-desktop, iselfowuni, iwebhu kunye nokusetyenziswa okungaphakathi. Iinkqubo ezininzi zomthombo ovulekileyo zibhalwa kusetyenziswa iJava.
Impikiswano malunga neelayisensi zabo
Uninzi lwezinto zeqonga leJava ziyafumaneka phantsi kweelayisensi ezivuliweyo, kwaye, ezo zingakhange zithathelwe indawo zezinye iiprojekthi eziyimithombo evulekileyo. Nangona kunjalo, esi ayisosiqinisekiso. I-Oracle (ethe yathenga i-Sun Microsystem) imangalela uGoogle ngokumiliselwa kwakhona kweenkqubo zesicelo seJava kwi-Android. Iziphumo zolu gwebo ziya kuxhomekeka ekubeni izinto ezinokutshintsha zinokuqhubeka nokusetyenziswa.
Sebenzisa usetyenziso lweJava kwiLinux
Uninzi lwezicelo zeJava zibandakanya imodyuli encinci evumela ukuba zisetyenziswe ngaphandle kwesidingo sokufaka izinto ezongezelelweyo. Nangona kunjalo, ukubaleka uninzi kufuneka ufake indawo yexesha lokusebenza kweJava. Uninzi lwe Ulwabiwo lweLinux lubandakanya iphakheji ebizwa ngokuba yi-OpenJDK kwiindawo zokugcina zabo ezinokufakwa ngendlela eqhelekileyo.
Unako kwakhona ukufaka indawo esemthethweni yexesha lokubaleka kwiphepha lakho. Kodwa inelayisensi kuphela kwaye inezithintelo ekusebenziseni urhwebo.
Kuzo zombini iimeko, kuya kufuneka ubeke isikhombisi semouse ngaphezulu kwesicelo kunye neqhosha lasekunene ukhethe ukulivula ngendawo ekhethiweyo yeJava.
Inkqubo kwiJava
Ukwenza iinkqubo kwiJava kuphela nKufuneka sifake le phakheji ye-OpenJDK esele ikhankanyiwe kunye nemeko yophuhliso oluhlangeneyo NjengeNetBeans, i-Eclipse, okanye i-Intellij Idea. TZonke zinokufakwa ngokulula kulwabiwo lweLinux usebenzisa oovimba kunye neephakeji zePlPPak kunye ne-Snap.
