Cov khoom tsis hloov pauv tau tuaj yeem siv tau hauv ntau cov ntawv thov. Ntau cov xov tuaj yeem ua rau cov ntaub ntawv sawv cev los ntawm cov khoom hloov pauv tsis muaj kev txhawj xeeb ntawm cov ntaub ntawv raug hloov los ntawm lwm cov xov. Yog li ntawd, cov khoom tsis hloov pauv tau suav tias yog cov xov zoo dua li cov khoom sib hloov.
Dab tsi yog qhov taw qhia ntawm cov khoom hloov tsis tau?
Kev tso siab siab tshaj plaws ntawm cov khoom tsis hloov pauv tau txais dav raws li lub suab zoo rau kev tsim cov lej yooj yim, txhim khu kev qha. Cov khoom tsis hloov pauv tau tshwj xeeb yog qhov tseem ceeb hauv cov ntawv thov sib txuam. Txij li thaum lawv hloov tsis tau lub xeev, lawv tsis tuaj yeem raug cuam tshuam los ntawm xov cuam tshuam lossis pom hauv lub xeev tsis sib xws.
Yam khoom twg yuav tsum hu ua hloov tsis tau?
Imutable objects yog tsuas yog cov khoom uas nws lub xeev (cov khoom cov ntaub ntawv) hloov tsis tau tom qab kev tsim kho. Piv txwv ntawm cov khoom tsis hloov tau los ntawm JDK suav nrog String thiab Integer. Cov khoom tsis hloov pauv tau yooj yim heev rau koj qhov kev pab cuam, vim lawv: yooj yim rau kev tsim, sim, thiab siv.
Yuav ua li cas koj siv cov khoom hloov tsis tau?
Txhawm rau tsim cov khoom hloov pauv tsis tau koj yuav tsum ua raws qee cov cai yooj yim:
- Tsis txhob ntxiv cov txheej txheem setter.
- Tshaj tawm tag nrho cov teb kawg thiab ntiag tug.
- Yog tias daim teb yog ib qho khoom sib hloov tau tsim cov ntawv tiv thaiv ntawm nws rau txoj kev tau txais.
- Yog tias qhov khoom sib pauv tau dhau mus rau tus tsim tsim yuav tsum raug xa mus rau thaj chaw tsim ib daim ntawv tiv thaiv ntawm nws.
Peb nyob qhov twgsiv immutable class hauv Java?
chav kawm tsis hloov pauv ua kev sib koom ua ke yooj yim dua. Cov chav kawm hloov pauv tsis tau ua kom paub tseeb tias cov txiaj ntsig tsis hloov pauv hauv nruab nrab ntawm kev ua haujlwm yam tsis siv cov blocks synchronized. Los ntawm kev zam synchronization blocks, koj tsis txhob deadlocks.

Dab tsi yog qhov hloov pauv thiab hloov pauv hloov pauv?
Point mutations hloov ib leeg nucleotide. Frameshift kev hloov pauv yog ntxiv lossis tshem tawm ntawm nucleotides uas ua rau muaj kev hloov pauv hauv kev nyeem ntawv. frameshift thiab point mutation yog dab tsi? Ib qho kev hloov pauv cuam tshuam rau ib khub hauv paus.
Qhov kev hloov pauv no puas yuav ua rau muaj kev hloov pauv hloov pauv?
Yog li, yog tias muaj kev hloov pauv, piv txwv li, kev ntxig lossis tshem tawm ntawm nucleotide, tshwm sim, qhov no tuaj yeem ua rau kev hloov pauv ntawm kev nyeem ntawv. Nws hloov tag nrho cov amino acid ib ntus. Cov kev hloov pauv no yog hu ua frameshift mutation (tseem hu ua kev nyeem ntawv hloov pauv, nyeem ntawv hloov pauv, lossis framing yuam kev).
Puas yog jurassic ntiaj teb hloov pauv hloov pauv hloov pauv?
Qee zaum, paub meej, koj yuav tau rov qab mus rau lub sijhawm dhau los - txuag manually, thiab feem ntau, raws li game's autosave yog… tsis zam txim - tab sis feem ntau ntawm cov lub sijhawm koj tuaj yeem khaws cov khoom thiab khaws cia nrog.
Qhov twg yog qhov kev hloov pauv hloov pauv hloov pauv?
Semiconservative replication piav qhia txog cov txheej txheem ntawm DNA replication nyob rau hauv tag nrho cov paub hlwb. DNA replication tshwm sim ntawm ntau lub hauv paus pib ntawm kev rov ua dua raws DNA qauv strand. Raws li DNA ob chav helix yog unwound by helicase, replication tshwm sim nyias ntawm txhua tus qauv strand nyob rau hauv antiparallel cov lus qhia.
Qhov kev hloov pauv twg yog xav tias yuav cuam tshuam los ntawm kev hloov pauv hloov pauv?
Dependent Variable Qhov sib txawv uas nyob ntawm lwm yam uas ntsuas. Cov kev hloov pauv no yuav tsum tau hloov pauv raws li qhov kev sim ua haujlwm ntawm tus kheej hloov pauv lossis hloov pauv. Nws yog cov nyhuv presumed. Qhov kev tshawb fawb hloov pauv twg yog qhov tshwm sim?
