Encapsulation yog ib qho tseem ceeb ntawm OOP (object-oriented programming). Nws hais txog cov ntaub ntawv bundling nrog cov txheej txheem ua haujlwm ntawm cov ntaub ntawv ntawd. Encapsulation yog siv los nkaum qhov tseem ceeb lossis lub xeev ntawm cov khoom siv cov ntaub ntawv hauv chav kawm, tiv thaiv cov tog neeg tsis raug cai nkag mus rau lawv.

Ib yam li ntawd, encapsulation piav qhia yog dab tsi?

Encapsulation yog ib lub ntsiab lus tseem ceeb hauv object-oriented programming (OOP). Nws piav qhia txog lub tswv yim ntawm kev sib sau cov ntaub ntawv thiab cov txheej txheem uas ua haujlwm ntawm cov ntaub ntawv hauv ib chav, xws li chav kawm hauv Java. Lub tswv yim no feem ntau yog siv los zais qhov sawv cev sab hauv, lossis lub xeev, ntawm ib qho khoom los ntawm sab nraud.

Tsis tas li ntawd, dab tsi yog encapsulation thiab piv txwv? Encapsulation hauv Java yog txheej txheem ntawm wrapping code thiab cov ntaub ntawv ua ke rau hauv ib chav tsev, rau piv txwv , ib qho tshuaj ntsiav uas sib xyaw ntawm ntau yam tshuaj. Tam sim no peb tuaj yeem siv cov txheej txheem setter thiab getter los teeb tsa thiab tau txais cov ntaub ntawv hauv nws. Chav kawm Java Bean yog qhov piv txwv ntawm ib tug tag nrho encapsulated chav kawm

Ib yam li ntawd, nws raug nug, dab tsi yog encapsulation thiab nws cov txiaj ntsig?

Encapsulation - Cov Qhov tseem ceeb ntawm kev siv Object Oriented Programming lus zoo li Java yog tias nws muab koj cov cai - kev ruaj ntseg, yooj thiab nws yooj yim tswj los ntawm encapsulation . Encapsulation kuj tseem siv tau hauv kev zais tus cov ntaub ntawv (piv txwv li hloov pauv) ntawm chav kawm los ntawm kev nkag mus ncaj qha tsis raug cai.

Encapsulation yog dab tsi koj ua tiav nws li cas?

Encapsulation txhais tau tias yog kev sau cov ntaub ntawv nyob rau hauv ib chav tsev. Encapsulation tuaj yeem ua ua tiav los ntawm: Tshaj tawm tag nrho cov kev hloov pauv hauv chav kawm ua tus kheej thiab sau cov txheej txheem pej xeem hauv chav kawm los teeb tsa thiab tau txais cov txiaj ntsig ntawm qhov sib txawv.
