«Ngahlukana nentombi yami umqambi. Akayazi iJava »Ngezwa ihlaya okokuqala ngqa ohlelweni lomsakazo olubhekiswe emphakathini jikelele. Lokho kukhombisa lokho Ukuthandwa kwalolu limi lwezinhlelo lweminyaka engu-25 kudlula indawo yesayensi yamakhompyutha.
Igama Java lisetshenziswa esikhathini esiningi ukubhekisa kulo ipulatifomu yeJava, okungukuthi, isethi yamathuluzi wokuthuthukiswa okusheshayo kwezinhlelo zokusebenza ze-multiplatform, kanye nolimi lohlelo olujwayelekile eyenziwe yinkampani yeLanga ukuthuthukisa izinhlelo zale nkundla.
Umehluko weJava maqondana nezinye izilimi ezihlelayo ngukuthi Yenzelwe ukuthi ikhodi ebhaliwe ikwazi ukusebenza kunoma yiluphi uhlelo umshini obonakalayo ongasebenza kulo IJava (JVM).
Empeleni. IJava ayizalwanga ukuthi isetshenziswe ezinhlelweni zekhompyutha. Ngama-90s imboni yezindaba yayibheja kuthelevishini exhumanayo futhi abathuthukisi bacabanga ukuthi kuzoba wusizo ekusetshenzisweni kwama-decoder nokuthi yini ezokwaziwa kamuva ngokuthi amathelevishini ahlakaniphile. Kodwa-ke, izinkampani zethelevishini zentambo bezingenandaba. FKwakungabathuthukisi be-Intanethi ababona amandla ayo kanye neNetscape, isiphequluli sokuqala, wasifaka.
IJava iba neminyaka engama-25. Umlando omncane
Ukuqala kwephrojekthi kufanele kulandelwe ngonyaka we-1991 lapho uJU-Ames Gosling, Mike Sheridan, noPatrick Naughton bakha iqembu elibizwa ngeGreen Team enkampanini yeSun Microsystem (Ithimba eliluhlaza). Izinhloso zabo zazifisa ukuvelela, babefuna ukwakha ulimi lohlelo olwalukhona
Ilula, inamandla, iyaphatheka, ipulatifomu izimele, ivikelekile, isebenza kahle kakhulu, inemicu eminingi, ayakhelwanga ngaphakathi, iqondiswe entweni, ihumushiwe futhi inamandla.
Ekuqaleni ulimi lwangakusasa lwalubizwa nge-Greentalk futhi amafayela alo ayene-extension .gt kodwa ngokuhamba kwesikhathi igama lika-Oak lakhethwa. I-oki libhekwa njengophawu lwamandla futhi likhethwe njengesihlahla sikazwelonke emazweni amaningi njengeFrance, iJalimane, iRomania kanye ne-United States. Futhi, kwakuwuphawu lokuhweba olubhalisiwe lwenye inkampani.
Kungani uJava agcina ukubizwa?
Lapho onjiniyela bethola ukuthi abakwazi ukuyibiza nge-Oak bashintsha amanye amagamas. Babefuna igama elibonisa ingqikithi yolimi olusha: izinguquko, amandla, uyaphila, upholile, uhlukile, kulula ukubhalwa, futhi kumnandi ukusho.
Bavivinye amandla, izinguquko, uSilika, iJolt, ne-DNA. Ekugcineni, bakhetha igama uGosling aqhamuka nalo phezu kwekhofi. UJI-ava ayisona isifinyezo, ibhekisa esiqhingini sase-Indonesia lapho kukhiqizwa ezinye izinhlobo ezinhle kakhulu zalesi simiso.
Ngo-1995 kukhishwe inguqulo yokuqala yesilingo sethuluzi lonjiniyela futhi, ngawo lowo nyaka, umagazini i-TIme wawuqamba njengomunye wemikhiqizo eyishumi yonyaka. Namuhla ulimi isetshenziselwe ukudala izinhlelo zokusebenza zedeskithophu, iselula, iwebhu nezinhlelo ezishumekiwe. Izinhlelo eziningi zomthombo ovulekile zibhalwa kusetshenziswa iJava.
Impikiswano ngamalayisense abo
Iningi lezinto zepulatifomu leJava ziyatholakala ngaphansi kwamalayisense avulekile, futhi, lezo ezingathathelwanga isikhundla ngamaphrojekthi ahlukile angumthombo ovulekile. Kodwa-ke, lesi akusona isiqinisekiso. I-Oracle (ebithenge iSun Microsystem) imangalela iGoogle ngokuqaliswa kabusha kwezindawo zokufaka izinhlelo zeJava ku-Android. Umphumela walesi sinqumo uzoncika ekutheni ukufakwa esikhundleni kungaqhubeka yini ukusetshenziswa.
Isebenzisa izinhlelo ze-Java ku-Linux
Izinhlelo eziningi ze-Java zifaka imodyuli encane evumela ukuthi zisetshenziswe ngaphandle kwesidingo sokufaka ezinye izinto. Noma kunjalo, ukugijima iningi udinga ukufaka imvelo yesikhathi sokusebenza seJava. Okuningi Ukusatshalaliswa kweLinux kufaka iphakheji ebizwa nge-OpenJDK ezinqolobaneni zabo ezingafakwa ngendlela ejwayelekile.
Ungafaka futhi imvelo esemthethweni yesikhathi sokusebenza se-Oracle kusuka ekhasini lakho. Kepha inamalayisense kuphela futhi inemikhawulo yokusetshenziselwa ukuthengisa.
Kuzo zombili lezi zimo, kufanele ubeke isikhombisi segundane phezu kohlelo bese ngenkinobho yesokudla ukhethe ukusivula ngemvelo ekhethiwe yeJava.
Ukuhlela kuJava
Ukwenza izinhlelo kuJava kuphela nSidinga ukuthi kufakwe iphakethe le-OpenJDK eselikhulunywe ngenhla kanye nemvelo yentuthuko ehlanganisiwe njenge-NetBeans, i-Eclipse, noma i-Intellij Idea. TZonke zingafakwa kalula ekusatshalalisweni kweLinux usebenzisa amakhosombe namaphakeji we-FlatPak ne-Snap.
