Java Programming ulimi

Abaningi bethu baye babona wake izinhlelo, noma mhlawumbe nje wezwa ngakho. Ngesisekelo yesimiso uHlelo izilimi. izilimi Ukuhlela zifane olunye ulimi, kodwa lapha sikhuluma hhayi ngokuphathelene nendlela yokusebenzelana nabantu, futhi ngokukhuluma umshini - computer.

Kuyini kakhulu nomqondo ulimi lokwakha izinhlelo? Ngaphansi ulimi lokwakha ibeke uhlelo esisemthethweni uphawu ukuthi isetshenziswa ukuchaza algorithm ezihlukahlukene kuba ifomu ukuthi kwakuyoba lula ngomculi (isibonelo, i-computer). Noma yiluphi ulimi izinhlelo ichaza iqoqo imithetho syntactic, semantic futhi lucebe isicelo womshini uhlelo lwekhompyutha. Kuyasiza uMklami ukucacisa kahle izodluliselwa kanjani futhi idatha egciniwe lapho izenzakalo kuyoba yokusabela phezu ingxenye ikhompyutha, kanye lokho izenzo amaKristu okufanele ukwenziwa idatha ethile ngaphansi kwezimo ezihlukahlukene.

Njengoba kungenzeka uye ukuyichaza, uHlelo izilimi, kunezindlela eziningi, isibonelo, Pascal noma Java ulimi lokwakha izinhlelo. Kodwa zonke awela ezimbili eziyisisekelo amaqembu: izilimi ka ezingeni eliphezulu futhi ezingeni eliphansi.

Izilimi ezingeni eliphansi ngendlela ehlukile ngokuthi umhlangano ulimi. Kuyinto notation kuphela ongokomfanekiso asetshenziswa imiyalo ehlukene, okuyinto ngokushesha ngekhanda futhi kulula ukuyiqonda. Ngezinye izikhathi ulimi assembler ngokuthi autocode noma ngekhanda.

High-level izilimi ukudlala indima umlamuli phakathi kwekhompyutha nangabantu. Benza-ke kungenzeka ukuthi ixhumane ne-ikhompyutha ngendlela evamile kubantu. Ngaphambi kokubhala hlelo nganoma yiluphi ulimi lokhu ezingeni, uMklami kudingeka sokuhlanganiswa algorithm ukuxazulula inkinga, igxathu negxathu plan of action ayewadinga ukuze enze lo msebenzi. Algorithmic ulimi lokwakha izinhlelo - ulimi ezidinga algorithm, ihlanganiswe kusengaphambili.

Manje sizoxoxa ngalezi zilimi ethandwa kakhulu esikhathini sethu. Ngalokhu sisho Java ulimi lokwakha izinhlelo. Java ulimi lokwakha izinhlelo kanye platform Computing ngesikhathi esifanayo, eyakhishwa okokuqala ngo-1995 SunMicrosystems. Kuyinto ubuchwepheshe core evumela ukukhiqiza esiningi izinhlelo ezintsha, kuhlanganise ahlukahlukene, izicelo ibhizinisi kanye, yebo, imidlalo. Lolu limi usebenza izigidigidi amadivayisi ezahlukahlukene, kufaka phakathi omakhalekhukhwini nama-TV, kanye computer angaphezu kuka-860 kwezigidi ezingu emhlabeni wonke.

Java kufanele ifakiwe kukhompyutha yakho ngenxa ubukhulu uhlelo lwayo lokusebenza. Ngokwesibonelo, kukhona inani elikhulu webhusayithi kanye zokusebenza, omsebenzi wakhe oyokwenziwa kuphela ngaphansi kombandela wokuthi ozifakile Java. Cabanga nje indlela ebalulekile Java ulimi lokwakha izinhlelo. Wabuye lunikeza ukulondeka, ukuthembeka kanye nesivinini. Java zisetshenziswa cishe kuyo yonke indawo, kusukela amageyimu ukuba izikhungo idatha, kusukela laptops kwi-Inthanethi kusuka kumaselula ukuba anamandla ngokwesayensi.

Libuye isibuyekezo esibalulekile inguqulo yakho ye-Java. Inguqulo yakamuva, isibonelo, iqukethe izithuthukisi ezibalulekile ukuthuthukisa ukusebenza, ukuphepha nozinzo kwezicelo kwi-Java namalogo esetshenziswa kukhompyutha yakho. Izibuyekezo amahhala, futhi ungakwazi uwathole kalula kwi-Inthanethi.

Mayelana ukuthi kubaluleke ezobuchwepheshe zanamuhla nezindlela akudingeki phikisana. A Java ulimi lokwakha izinhlelo kudlala indima ebalulekile konke lokhu. Besingaba yini nje namuhla ngaphandle lolu limi, okuyinto oluthatha liyindawo efanelekayo phakathi kwamanye amalungu izwe elikhulu lwezinhlelo?
