Keeb kwm hom ntaub ntawv yog cov general andfundamental hom ntaub ntawv uas peb muaj nyob rau hauv Java thiab cov no yog byte, luv, int, ntev, ntab, ob npaug, char, boolean. Muab los hom ntaub ntawv yog cov uas tau ua los ntawm kev siv lwm yam hom ntaub ntawv Piv txwv li, arrays. Tus neeg siv txhais cov ntaub ntawv yog cov ntawd neeg siv / programmer nws tus kheej txhais.
Yog li ntawd, tus neeg siv txhais cov ntaub ntawv yog dab tsi?
A neeg siv - hom ntaub ntawv txhais (UDT) yog a hom ntaub ntawv uas tau los ntawm ib qho uas twb muaj lawm hom ntaub ntawv . Koj tuaj yeem siv UDTs los txuas ntxiv cov khoom tsim hom twb muaj thiab tsim koj tus kheej customized hom ntaub ntawv.
Ib sab saum toj no, vim li cas chav kawm hu ua tus neeg siv cov ntaub ntawv txhais hom hauv Java? Cov neeg siv - cov chav kawm uas tau teev tseg yog ib qho programming toobject-oriented thiab siv los sawv cev rau cov khoom uas nws cov ntaub ntawv tuaj yeem tiv thaiv, pib, thiab nkag mus los ntawm cov txheej txheem tshwj xeeb. Cov neeg siv - cov ntaub ntawv teev tseg typeand chav kawm ob leeg tuaj yeem muaj ntau qhov sib txawv ntawm qhov sib txawv hom ntaub ntawv . 3.4. 8 votes.
Kuj kom paub yog, dab tsi yog tus neeg siv txhais cov ntaub ntawv nrog piv txwv?
Tus neeg siv txhais cov ntaub ntawv hom yog hom ntaub ntawv tsim los ntawm tus tsim tawm siv primitive hom ntaub ntawv , thiab siv rau lub hom phiaj tshwj xeeb. Piv txwv : Tus neeg ua haujlwm ntawm lub txhab nyiaj muaj ntau yam cwj pwm, xws li lub npe, tus lej neeg ua haujlwm, nyiaj hli, chaw nyob, xov tooj.
Dab tsi yog tus neeg siv txhais cov chav kawm?
A chav kawm tuaj yeem tuav txhua hom ntaub ntawv, suav nrog cov xwm txheej ntawm cov chav kawm ua txhais . Cov chav kawm yog tus kheej muaj kom nws yooj yim siv tib yam chav kawm lwm daim ntawv thov. Piv txwv li, ib daim ntawv chav kawm uas muab cov ntaub ntawv tawm tswv yim / tso tawm ua haujlwm tuaj yeem sib koom nrog lwm cov ntawv thov.

Dab tsi ntawm algorithms xav kom tus neeg xa khoom thiab tus neeg txais kev sib pauv pauv tus yuam sij zais cia uas siv los xyuas kom tsis pub leej twg paub cov lus? Kev piav qhia: Symmetrical algorithms siv tib tus yuam sij, tus yuam sij zais cia, los encrypt thiab decrypt cov ntaub ntawv. Tus yuam sij no yuav tsum tau muab qhia ua ntej ua ntej kev sib txuas lus tuaj yeem tshwm sim
Cov chav kawm li cas yog tus neeg siv txhais cov ntaub ntawv?
Chav Kawm: Lub tsev thaiv ntawm C ++ uas ua rau Object-Oriented programming yog chav kawm. Nws yog tus neeg siv cov ntaub ntawv teev tseg, uas tuav nws tus kheej cov ntaub ntawv cov tswv cuab thiab cov tswv cuab kev ua haujlwm, uas tuaj yeem nkag mus thiab siv los ntawm kev tsim ib qho piv txwv ntawm chav kawm ntawd. Union: Zoo li Cov Qauv, union yog cov neeg siv cov ntaub ntawv teev tseg
Dab tsi yog tus lej ncaj qha uas yuav tsum raug tshem tawm ntawm cov ntaub ntawv tshawb fawb kom ua raws li kev siv cov ntaub ntawv txwv?
Cov ntaub ntawv qhia ncaj qha hauv qab no yuav tsum raug tshem tawm rau PHI kom tsim nyog raws li cov ntaub ntawv txwv: (1) Cov npe; (2) Cov ntaub ntawv chaw nyob xa ntawv, tsis yog lub nroog lossis nroog, xeev, thiab ZIP code; (3) xov tooj; (4) fax xov tooj; (5) email chaw nyob; (6) social security naj npawb; (7) cov ntaub ntawv kho mob; (8) kev npaj kho mob
Dab tsi yog cov teeb meem ntawm kev tswj cov ntaub ntawv hauv cov ntaub ntawv ib txwm muaj?
Nyob rau tib lub sijhawm, qhov kev tswj hwm cov ntaub ntawv ib puag ncig tsim teeb meem xws li cov ntaub ntawv rov ua dua thiab tsis sib xws, cov kev pab cuam-cov ntaub ntawv dependence, inflexibility, tsis muaj kev ruaj ntseg, thiab tsis muaj cov ntaub ntawv sib qhia thiab muaj
Dab tsi yog cov ntaub ntawv kos npe lossis cov ntaub ntawv headers raws li siv hauv digital forensics?
Hom Cov Ntaub Ntawv Ib daim ntawv kos npe yog ib qho tshwj xeeb ntawm kev txheeb xyuas bytes sau rau hauv cov ntaub ntawv header. Ntawm lub Windows system, cov ntaub ntawv kos npe ib txwm muaj nyob hauv thawj 20 bytes ntawm cov ntaub ntawv. Cov ntaub ntawv sib txawv muaj cov ntaub ntawv sib txawv; Piv txwv li, Windows Bitmap duab file (
