Cov neeg tsim khoom parameterized yog cov neeg tsim khoom muaj tus lej tshwj xeeb ntawm cov lus sib cav kom dhau Lub hom phiaj ntawm tus neeg tsim khoom parameterized yog txhawm rau muab cov neeg siv xav tau tshwj xeeb rau qhov piv txwv sib txawv ntawm qhov sib txawv khoom. Tus tsim qauv parameterized yog sau qhia meej los ntawm tus programmer.
Pab parameterized constructor muab piv txwv yog dab tsi?
Example of Parameterized Constructor
Piv txwv, thaum peb tsim cov khoom zoo li no MyClass obj=tshiab MyClass(123, "Hi"); ces lo lus tseem ceeb tshiab invokes tus Parameterized constructor nrog int thiab hlua tsis (MyClass(int, String)) tom qab khoom tsim.
Dab tsi yog parameterized hauv Java?
Ib hom parameterized yog an instantiation ntawm ib hom generic nrog tiag tiag cov lus sib cav … Hom parameter E yog qhov chaw tuav uas yuav tom qab hloov los ntawm hom kev sib cav thaum lub generic hom yog instantiated thiab siv. Qhov instantiation ntawm ib hom generic nrog cov lus sib cav tiag tiag yog hu ua hom parameterized.
Dab tsi yog qhov sib txawv ntawm tus tsim qauv tsim thiab tus tsim qauv parameterized?
Tus tsim lub neej ntawd yog tus tsim tsim uas lub compiler tau txais kev tsim tawm thaum tsis muaj tus tsim qauv tsim los ntawm programmer. Conversely, tus parameterized constructor yog ib tug constructor uas tus programmer tsim nrog ib tug los yog ntau tsislos pib qhov piv txwv ntawm cov chav kawm.
Dab tsi yog cov yam ntxwv ntawm tus qauv tsim qauv?
Parameterized constructors
Thaum ib qho khoom raug tshaj tawm hauv tus tsim khoom parameterized, tus nqi pib yuav tsum dhau los ua kev sib cav rau tus tsim ua haujlwm Txoj kev ib txwm ntawm kev tshaj tawm cov khoom yuav tsis ua haujlwm. Cov neeg tsim khoom tuaj yeem hu tau meej lossis implicitly.
