Ngaba iJava kufanelekile ukuba ifundwe?

Ngaphandle kwe-OpenOffice, Vuze, Woopra, Okanye applet ukuba zenzeka ezithile websites, kuba iinkqubo mobile kakhulu positioning, TV, GPS,-ATM, iinkqubo zoshishino kunye ezininzi amaphepha abahamba yemihla ngemihla iyasebenza ku Java.

Le tshati ilandelayo ibonisa indlela ubuchwepheshe Java abe domain ngamandla ukususela 2006 2011 kuthelekiswa C # .net, PHP kunye Ruby, mhlawumbi esathathwayo esasilandela inikeza umsebenzi.

iJava

Kwimeko yesimo se geospatial, iC ++ kunye neJava yimihlaba emibili ephakamileyo apho i-App Source Source iyakhiwe; Itheyibhile elandelayo ifingqa into ethile, ngenxa yesigxina sesithuba ndigxila ekunyuseni kwizicelo zeJava kodwa ekuqalekeni (okungekho), kwicala leJava lidlulile kwiC ++ ebubudlelwaneni 15 ku-10.

Kwinqanaba ledesktop

 

  • I-GUM ye-Quantum. Olona phunyezo lusebenzayo kwimeko yeAnglo-Saxon, ikhatshwa ngokubanzi yiGrass.
  • GRASS. Inkqubo endala ye-OpenSource, ene-raster ephambili.
  • yomlando. Uzalelwe eJamani, ujolise phambili kuphando.
  • Ilwis. Initiative eyazalelwa eHolland, kwaye nangona isuka phakathi kwiminyaka yee-XNUMX, ukukhula kwayo phantsi komdibaniso woluntu akulunganga.

 

  • gvSIG.  Ngokufanelekileyo esasazwe ngokubanzi isicelo se-OpenSource kwindawo ye-Hispanic, kwaye mhlawumbi leyo inombono wobundlongondlongo bamanye amazwe. Ukuza kuthi ga ngoku ngaphezulu kwe-100 yam amanqaku akhomba kwesi sixhobo.
  • SEXTANTE. Ukukhuthazwa yiDyunivesithi yase-Extremadura, isincedisi esikhulu kwi-gvSIG, nangona kukho amathala eencwadi e-OpenJump, eKosmo kwaye iyadibana ne-GRASS.
  • UDig. Olu lucoceko, ukuba ngaba ukusasazwa okungaphantsi kophuhliso olunokubakho okuphezulu, okwenziwe yinkampani efanayo yePostGIS, iGeoServer kunye neGeotools.
  • IKosmo. Ndisebenza e-OpenJump, ndizalelwe eSpain.
  • OpenJump. Ilifa lelinge laseKhanada elibizwa ngokuba yiJump, elalingasasebenzi.
  • CatMDEdit. Lo ngumhleli wemethadatha.

Kwinqanaba lomncedisi

  • ImephuServer. Isasazeke kakhulu, nangona inkqubela phambili kancinci kuphuhliso kunye nokudityaniswa kuneGeoserver.
  • Imephu yeGuide OS. Ixhaswe yi-AutoDesk, yomelele kakhulu.

 

  • GeoServer. Isenokuba yeyona seva yedatha esetyenziswa kakhulu.
  • GeoNetwork. Ngumphathi wekhathalogu yemetadast, efanelekileyo yegopopal okanye indlu yokucoca.
  • Degree. I-Initiative ezalwe kwiYunivesithi yaseBonn, eJamani, enekhono elilinganayo neGeSServer.

i-course-javaUkusuka apha ngasentla, ubuncinane 5 ezenzeka kwi Java lubalwa iiprojekthi OSGeo Foundation, abanye bafukanywe, ekhangela uzinzo complementarity.

Kuya kuba lunomdla ukuba netafile ejikelezayo yeengcali zenkqubo ukuba zithethe malunga nokuba kutheni bekhetha okanye bayithiyile iJava, kunokwenzeka ukuba kuxoxwe ngokuba ingaba ii-pointers ziyenza inkqubo ilula okanye akunjalo, ukuba ukufundwa okuninzi kuya kuba nethuba ngaphezulu kwezinye iilwimi ukuba akukho matshini, ukuba ukhuseleko luhlobene. ; kodwa kwinto enye bayavumelana bonke:

Inyani yokuphindaphindeka, kuba usetyenziso lunokuqhuba kwiWindows, iLinux, iSolaris kunye neMac (ukungahoyi inkani yakutshanje kaSteve Jobs). Oku kuyenza ibe nomtsalane kwizicelo ezinobubanzi behlabathi, apho abasebenzisi baya kusebenzisa iinkqubo ezahlukeneyo zokusebenza kunye neebrawuza, ukusombulula phantse yonke into ngoMatshini oQhelekileyo odumileyo ngaphandle kokwenza imisebenzi emininzi, esombulula ingxaki yokuphatheka kwaye inike ukuhluza okukhuselekileyo phakathi umxhasi kunye neseva.

Kwakhona yokuba Open Source ngumba ukuvavanya, nangona Oracle wafumana SUN (Java umbhekisi phambili), yaye ezinye ukuthandabuza ukuba oko kuya kwenzeka kwixesha elizayo kunye SQL (mvume GLP), phantse akukho namnye imibuzo elizayo ulwimi lweJava.

Ngokunokwenzeka oko i-Green Teen yaqala njengeprojekthi engaphumeleliyo ukuqhuba kumabonakude kwaye i-VHS ayisafani noko kuphunyezwe yiJava ekubekeni, nangona isenza iinjongo. Ukuza kuthi ga ngoku, zintathu izicelo zeJava:

 

iimveliso zeJava

I-J2SE (i-Standard Edition), eyona isetyenziswa ngokubanzi ekwakhiweni kwezicelo ezipapashwe kunye nama-applets.

I-J2EE (I-Edishini yoShishini), ngokuqhelekileyo kumatye e-multilayers, kwiinkxaso ezikude kunye nezorhwebo.

I-J2ME (i-Micro Edition), apho izixhobo zeefowuni, i-GPS kunye neebhokisi ze-TV zedijithali zakhiwa.

Learn21 y Globalmentoring Ziyimimiselo yamagumbi okufundela apho ungafunda khona iJava.

 

Ngoko, kubuyela kumbuzo wokuqala, ukuba iJava iyafaneleka ukufunda ...

Ewe.
