Ngaba kuluncedo ukufunda Java?

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.

Izicelo ze-GIS ku-C ++

Izicelo ze-GIS kwiJava

Kwinqanaba ledesktop

  • I-GUM ye-Quantum. Eyona ndlela iphunyezwe kakhulu kwiNgingqi yase-Anglo-Saxon, ngokuqhelekileyo ihamba neGrass.
  • GRASS. Inkqubo ye-OpenSource endala, ebalulekileyo kwi-raster.
  • yomlando. Wazalelwa eJamani, ngokugxininiswa ngokuphambili kwiphando.
  • Uluhlu Iprojekthi eyazalwa eHolland, kwaye nangona ivela kwiminyaka eyi-80, ukuphuhliswa kwayo phantsi kokubandakanya uluntu kuyimpofu.

  • gvSIG. Mhlawumbi isisicelo esisasazwa kakhulu kwi-OpenSource kwisiqhelo seSpanishi, kwaye mhlawumbi omnye nombono onobukrakra wehlabathi jikelele. Ukuza kube ngaphezu kwe-100 yamanqaku am, akhomba kwesi sixhobo.
  • SEXTANTE. Ukukhuthazwa yiYunivesithi yase-Extremadura, incedisa kakhulu i-gvSIG, nangona kukho iilayibrari ze-OpenJump, iKosmo kunye nokudibanisa ne-GRASS.
  • UDig. Olu luphuhliso olucacileyo, nangona lukhutshwe kancinci, olunamandla, oludalwe yinkampani efanayo ye-PostGIS, iGoSServer neGeotools.
  • IKosmo. Ndisebenza ku-OpenJump, ozalelwa eSpanish.
  • OpenJump. Ifa lomsebenzi weCanada obizwa ngokuba yiJump, oye wayeka.
  • CatMDEdit. Lo ngumhleli weemethadatha.

Kwinqanaba lomncedisi

  • MapServer. Ixhaphake kakhulu, nangona kukho inkqubela phambili ekuphuhliseni nasekuhlanganiseni okufutshane kuneGeoserver.
  • MapGuide OS. Exhaswa yi-AutoDesk, inamandla kakhulu.

  • GeoServer. Kungenzeka ukuba ngumsebenzisi wesetyenzisi esetyenziswa kakhulu.
  • GeoNetwork. Ingumphathi wekhathaloji yemethadatha, ilungele ukufa okanye ukucima indlu.
  • 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 nomdla a eziphakam iingcali zokuhlela ukuthetha malunga kutheni ukhetha okanye intiyo Java, mhlawumbi kuxoxwa ukuba yokukhomba okanye nqubo elula, ukuba amandla multithreading aventajaría nezinye iilwimi ayisekho kumatshini onesiqhamo ukuba ukhuseleko kubalulekile ; kodwa enye into ndiqinisekile wonke umntu uyavumelana:

Inyaniso yokuba yi-platform-cross platform, kuba izicelo zingasebenza kwi-Windows, Linux, Solaris kunye ne-Mac (ukuphazamisa ukunyaniseka kukaSteve Jobs nje). Oku kubangela ukuba babe ubenomtsalane izicelo omhlaba, apho abasebenzisi ziya kusebenzisa iinkqubo zokusebenza ezahlukeneyo kunye bakhangeli beencwadi, iingxaki phantse yonke into kunye Umatshini odumileyo Virtual ngaphandle ekwenzeni imisebenzi multithreaded, elisombulula ingxaki yokusiwa ngapha nangapha futhi inikezela ucoco ekhuselekileyo phakathi umxhasi kunye nomncedisi.

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.

Mhlawumbi oko kuqaliswe i-Teen Green kuba iphrojekthi ehlukileyo yokusebenza kwiTV kunye neVHS ayisabonakali ngathi iJava iphumelele ekumiseni, nangona yenzayo kwiinjongo. Okwangoku, izicelo zeJava zi-3:

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.
