Java Programming Language

Abaninzi kuthi baye ngonaphakade kweenkqubo, okanye mhlawumbi nje weva ngalo. Isiseko zenkqubo lwenkqubo iilwimi. iilwimi lwenkqubo ziyindawo ulwimi lwasemzini, kodwa apha sithetha nje malunga usebenza nabantu, yaye ngokunxibelelana kumatshini - ikhompyutha.

Yintoni kanye ingqiqo ulwimi lokuprograma? Phantsi ulwimi lokuprograma vule inkqubo esesikweni uphawu esetyenziswa ukuchaza ubuchule ezahlukeneyo oko ngendlela eza kuba lula njengophume (umzekelo, ikhompyutha). Naluphi na ulwimi lokuprograma ichaza uluhlu lwemithetho syntactic, lwesemantiki kunye lungelelanisa isicelo ekwenziweni kwenkqubo yekhompyutha. Inceda umdwelisi nkqubo yokwazi ukuba uza kusasazwa ize igcinwe data apho iziganeko ziya kuba basabela phezu inxalenye computer, ngokunjalo nezenzo kufuneka izakwenziwa idatha ethile phantsi kweemeko ezahlukeneyo ngayo.

Njengoko unokuba ugqibe lwenkqubo iilwimi, kukho ezininzi, umzekelo, Pascal okanye Java ulwimi lokuprograma. Kodwa bonke awela ezimbini ezingundoqo kumaqela: iilwimi of kwinqanaba eliphezulu kwinqanaba elisezantsi.

Iilwimi izinga eliphantsi ngokwahlukileyo ekuthiwa ulwimi ibandla. Kuyinto notation kuphela zokomfuziselo imiyalelo ezahlukeneyo asetyenziswa, ezithi ngentloko ngokukhawuleza kwaye kube lula ukuyiqonda. Ngamanye amaxesha ulwimi assembler ekuthiwa autocode okanye mnemonic.

iilwimi kwinqanaba eliphezulu kudlala indima umlamleli phakathi ikhompyutha kunye nabantu. Zenza kube lula ukunxibelelana nalo ngekhompyutha ngendlela eqhelekileyo abantu. Phambi kokubhala inkqubo kulo naluphi na ulwimi kweli nqanaba, uhlelo kufuneka algorithm ekuqulunqweni ukusombulula le ngxaki, inyathelo isicwangciso inyathelo amanyathelo afunekayo ukwenza lo msebenzi. ulwimi Algorithmic lokuprograma - ulwimi ezifuna algorithm, oluqulunqwe kwangaphambili.

Ngoku siza kuthetha olunye lweelwimi zithandwa ngexesha lethu. Ngale nto sithetha Java ulwimi lokuprograma. Java ulwimi lokuprograma kunye umgangatho wecomputing ngexesha elinye, nto leyo wakhululwa okokuqala ngqa ngo-1995 yi SunMicrosystems. It is a iteknoloji ongundoqo evumela ukuvelisa izixa ezikhulu iinkqubo ezintsha, kuquka Unezixhobo ezininzi, izicelo zoshishino, kakade, imidlalo. Olu lwimi isebenza iibhiliyoni izixhobo ezahlukeneyo, kubandakanywa neefowuni ezingasebenzi mobile nomabonakude, kwakunye ngaphezu kwezigidi 860 iikhompyutha zobuqu ehlabathini lonke.

Java kufuneka efakwe kwikhompyutha yakho ngenxa ubukhulu isicelo sayo. Umzekelo, kukho inani elikhulu leendawo web kunye izicelo, umsebenzi siya kwenziwa kuphela phantsi komqathango ukuba sele efakiwe Java. Cinga nje kubaluleke kangakanani le Java ulwimi lokuprograma. Kwakhona inika ukhuseleko, ukuthembeka kunye nesantya. Java zisetyenziswa Phantse kuyo yonke indawo, ukususela midlalo kumaziko data, ukususela laptops kwi Internet ukusuka iifowuni eziphathwayo ukuba computer zenzululwazi.

Kwakhona uhlaziyo ebalulekileyo inguqulo yakho ye Java. Inguqulo entsha, umzekelo, iqulathe izincedisi ezibalulekileyo nokuphucula intsebenzo, ukhuseleko kunye nozinzo izicelo Java-based lisetyenziswa kwi khomputha yakho. Updates bakhululekile, kwaye unako lula kwi-Internet.

Malunga nendlela kubaluleke ubugcisa bale mihla kwaye musa ukuba baxabane. A Java ulwimi lokuprograma ludlala indima ebalulekileyo konke oku. singenza ngayo kwimisibenzi ntoni namhlanje ngaphandle olu lwimi, nto leyo ithatha indawo ufanelwe phakathi kwezinye amalungu zehlabathi enkulu kweenkqubo?
