Access Modifiers Hom . C# muab plaub hom ntawm nkag mus modifiers : ntiag tug, pej xeem, tiv thaiv, sab hauv, thiab ob qho tib si: tiv thaiv-hauv thiab ntiag tug-tiv thaiv.

Ib tug kuj yuav nug, dab tsi yog qhov txwv tsis pub nkag mus hloov kho? Tus kheej
Ib yam li ntawd, dab tsi yog qhov sib txawv nkag mus hloov pauv hauv Java?
Java muab kev tswj xyuas los ntawm peb lo lus tseem ceeb - tus kheej , tiv thaiv thiab pej xeem. Peb tsis tas yuav siv cov kev hloov pauv kev nkag mus ib txwm, yog li peb muaj lwm qhov hu ua " ua ntej nkag", "package- tus kheej "los yog "tsis muaj kev hloov pauv".
Vim li cas peb thiaj siv cov kev hloov pauv hloov?
Access modifiers yog siv rau encapsulation: lawv tso cai rau koj los npaj koj cov cai hauv cov pob khoom thiab cov chav kawm, thiab tsuas yog muaj "kev cai" pej xeem cuam tshuam pom rau sab nraud, thaum zais cov ntsiab lus siv (uas koj xav tau. ua , yog li koj tuaj yeem hloov pauv yam tsis tau qhia leej twg).

Dab tsi yog qhov sib txawv ntawm qhov sib xyaw ua ke thiab qhov qub txeeg qub teg?
Txawm hais tias ob qho tib si Inheritance thiab Composition muab code reusablelility, qhov sib txawv tseem ceeb ntawm Composition thiab Inheritance nyob rau hauv Java yog tias Composition tso cai rov qab siv code yam tsis tau ncua nws tab sis rau Inheritance koj yuav tsum ncua chav kawm rau ib qho kev rov qab siv code lossis functionality
Dab tsi yog qhov qub txeeg qub teg Dab tsi yog qhov sib txawv ntawm qhov qub txeeg qub teg piav nrog piv txwv?
Inheritance yog ib txoj hauv kev kom tau txais cov yam ntxwv thiab kev coj cwj pwm ntawm ib chav kawm los ntawm lwm chav kawm. Cov chav kawm uas cov tswv cuab tau txais qub txeeg qub teg yog hu ua chav kawm hauv paus, thiab chav kawm uas tau txais cov tswv cuab tam sim no hu ua chav derived. Inheritance siv IS-A kev sib raug zoo
