Hloov kev nkag mus rau thaj chaw - Cov kev hloov pauv nkag public, pob, tiv thaiv, thiab ntiag tug tsis muaj txiaj ntsig rau lub peev xwm ntawm serialization los muab cov txiaj ntsig rau thaj teb.
Qhov twg ntawm cov kev hloov pauv hauv qab no Tsis tuaj yeem ua raws Mcq?
Kev piav qhia: Txhua qhov hloov pauv zoo li qub thiab hloov pauv hloov pauv tsis yog serialized.
Cov kev hloov pauv twg tsis tuaj yeem suav tau?
Ib qhov hloov pauv zoo li qub tsis tuaj yeem raug txheeb xyuas. Thaum de-serializing tus nqi tuaj yeem muaj rau Static variables yog tias tib yam yog muab thaum pib ntawm chav kawm hauv paus.
Dab tsi yog qhov tsis tuaj yeem ua hauv Java?
Yog tias koj cov khoom muaj kev siv (kev hloov pauv lossis ncaj qha) rau ib qho twgtsis yog cov khoom siv sib txuas, thiab qhov kev siv no tsis raug cim nrog cov lus tseem ceeb, ces koj cov khoom yuav tsis ua serializable. Feem ntau, nws tsis muaj kev nkag siab zoo rau serialize cov khoom uas tsis tuaj yeem rov qab siv tau thaum deserialized tom qab lossis lwm qhov.
Cov chav kawm Java twg tsis tuaj yeem ua tau?
Serializable interface. Qhov no tsuas yog ib qho cim interface uas qhia rau Java platform tias cov khoom yog serializable. Qee cov chav kawm theem xws li Xov, OutputStream thiab nws cov subclasses, thiab Sockettsis yog serializable.

Puas yog qhov hloov pauv hloov tau tuaj yeem hloov kho?
Qhov kev ywj pheej (lossis tswj hwm) qhov sib txawv yog qee yam uas tus kws sim lub hom phiaj hloov pauv lossis txawv ntawm qhov kev tshawb nrhiav. Qhov dependent (los yog teb) sib txawv yog ib qho uas tau pom thiab yuav hloov pauv hauv cov lus teb rauqhov sib txawv ntawm tus kheej .
Qhov twg ntawm cov hlau hauv qab no tuaj yeem muab rho tawm los ntawm autoreduction?
Qhia: Cov txheej txheem txo nws tus kheej yog cov txheej txheem kev lag luam dav siv ntawm cov hlau rho tawm los ntawm cov zaub mov lossis cov ore tshwj xeeb tshaj yog rau cov hlau tsis tshua muaj electropositive xws li tooj liab (Cu), lead (Pb), mercury (Hg) thiab lwm yam .
Qhov twg hauv qab no yog qhov tsis muaj zog ntawm txoj kev them rov qab?
Txawm hais tias txoj kev no muaj txiaj ntsig zoo rau cov thawj tswj hwm kev txhawj xeeb txog cov nyiaj tau los, qhov tsis muaj zog loj ntawm txoj kev no yog tias nws tsis quav ntsej lub sijhawm tus nqi ntawm cov nyiaj, thiab nws tsis quav ntsej cov nyiaj ntws tom qab lub lub sijhawm them rov qab .
Qhov twg ntawm cov tshuaj hauv qab no ntawm diazotization ua raws li kev sib txuas?
Teb: Cov tshuaj ntawm diazotization ua raws li kev sib txuas nrog yog p-Toluidine becoz nws yog thawj cov tshuaj tsw qab amines. thawj amines lossis thawj cov tshuaj tsw qab amines yog cov nucleophiles zoo uas yog vim li cas lawv tau txais kev sib txuas lus.
Dab tsi ntawm cov hauv qab no cuam tshuam nrog kev hloov pauv ntawm cov dej hauv photosynthesis?
Manganese (Mn 2 + ) yog siv rau photolysis ntawm dej los tsim oxygen thiab electrons thaum lub teeb tshwm sim ntawm photosynthesis. Nws yog qhov tshwm sim ntawm kev tawg ntawm cov dej mus rau hauv hydrogen thiab oxygen nyob rau hauv lub illuminated chloroplast.
