Tsis zoo li Java lossis C ++, peb tsis tuaj yeem txhais tau ntau constructors hauv python . mas, we ua tau txhais ib tug default value yog hais tias ib tug tsis dhau los yog peb siv tau *args, **kwargs as arguments.
Cov lus nug tseem yog, koj puas tuaj yeem muaj ntau tus tsim?
Ib chav kawm tuaj yeem muaj ntau tus tsim qauv , tsuav yog lawv kos npe (cov tsis lawv coj) tsis zoo ib yam. Koj ua tau txhais raws li ntau tus tsim raws li koj xav tau . Thaum Java chav kawm muaj ntau constructors , peb hais tias lub tus tsim yog overloaded (los hauv ntau versions).
Ib yam li ntawd, koj puas tuaj yeem overload constructors hauv Python? Peb kawm txog parameterized thiab tsis-parameterized Python Constructors , lub neej ntawd Python Constructor , tus kheej lo lus tseem ceeb, khoom tsim, thiab khoom pib. Tsis tas li ntawd, peb pom tias tsis muaj ib yam li constructor overloading hauv Python . Tseem, yog koj muaj lus nug, xav tias dawb nug hauv cov lus tab.
Kuj Paub, muaj pes tsawg tus neeg tsim khoom tuaj yeem muaj Python?
Peb muaj ob hom tus tsim hauv Python.
Dab tsi yog constructors hauv Python?
A tus tsim yog ib hom kev tshwj xeeb uas Python hu thaum nws instantiates ib yam khoom siv cov ntsiab lus pom hauv koj chav kawm. Python tso siab rau tus tsim los ua cov dej num xws li pib (xws li muab qhov tseem ceeb rau) ib qho piv txwv hloov pauv uas tus kwv yuav xav tau thaum nws pib.

Puas tuaj yeem sim muaj ntau tus ntes hauv Java?
Java ntes ntau qhov kev zam Ib sim thaiv tuaj yeem ua raws los ntawm ib lossis ntau qhov ntes blocks. Txhua qhov thaiv thaiv yuav tsum muaj qhov sib txawv tshwj xeeb handler. Yog li, yog tias koj yuav tsum ua cov haujlwm sib txawv ntawm qhov tshwm sim ntawm qhov sib txawv, siv java multi-catch block

Puas muaj tus qauv tsim qauv hauv Java?
Tsis muaj tus qauv tsim qauv hauv Java. Txawm li cas los xij, peb tuaj yeem luam tawm qhov tseem ceeb ntawm ib qho khoom mus rau lwm qhov zoo li luam tus tsim hauv C ++
