Java Programming Questionnaire

Cesar Becerra Santamaria

Mayelana nalolu hlelo lokusebenza

Uhlelo lokusebenza lufaka phakathi iqoqo lemibuzo ukuhlola ulwazi lwakho lweJava kanye nemodyuli evumela umfundi ukuthi abhale isizathu sokuthi kungani akhethe impendulo yanoma yimuphi umbuzo.

Ngokwengeziwe, izivivinyo esihlokweni ngasinye kuhlongozwa ukuba umfundi athuthukise futhi asebenzise ulimi lweJava.

Imibhalo ehlotshaniswa nohlu lwemibuzo ngalunye, kanye nemibuzo ngayinye, ingasetshenziswa ukutadisha izihloko zombuzo ngamunye futhi ufunde izici ezintsha ezibalulekile zolimi lweJava.

Lapho usuqedile ukuphendula uhlu lwemibuzo, uhlelo lukuvumela ukuthi ubone ukuthi izimpendulo ozikhethile beziqinisile yini.

Isihloko umsebenzisi azosithola futhi angasibuyekeza ohlwini lwemibuzo sithi:

Ama-opharetha nezinhlobo zedatha:
- Izinhlelo zokubala: idesimali, i-octal ne-hexa
- Isikhunta (cast)
- Ukulandelana opharetha
- Ukugcinwa kwezinombolo ezingezinhle
- Ama-opharetha we-Bitwise ne-arithmetic
- Funda bese ubhala imiyalelo

Abasebenza ngokuqondakalayo nobudlelwano

Ukuhlukahluka kohlobo lweBoolean

Imiyalo yesinqumo
- I switch imfundo
- ikhefu,
- uma kungenjalo, isidleke
- uma isitatimende? :

Imijikelezo
- for, while and do-ngenkathi
- Ukusebenza kwe-accumulator ngaphakathi komjikelezo
- Ukubalwa kwe-factorial.
- Umsebenzi we-Math.random ()
- Izinhlanganisela C (n, r)
- Ukulandelana kweFibonacci
- Ukuphatha isidleke somjikelezo nangesikhathi

Amalungiselelo
- Izinkambo ezinama-indices
- Imijikelezo eyakhiwe
- Incazelo yamalungiselelo.
- Qalisa ekuchazeni kwakho
- Qalisa ukusebenzisa imijikelezo
- Ingxenye yamalungu afanayo asetshenziswe njengenkomba yolunye uhlu
- Ukuguqulwa komlingiswa abe inombolo
- Izinhlelo ezinamalungiselelo amabili

- Izindlela nezimpawu
- Abakhi bayalayisha ngokweqile
- Ipharamitha ngenani nangereferensi
- Ukusetshenziswa kokuguquguqukayo kwasendaweni
- Izindlela zokushaya ucingo zisebenzisa izinto
- Ububanzi eziguquguqukayo
- Umsebenzi womphakathi we-static void main ()
- Ubudlelwano phakathi kwamakilasi:
Ukwakheka
Ukuhlanganisa
Inhlangano

Amakilasi eJava
