Yog tias koj txoj cai ua haujlwm nyob rau hauv ib puag ncig ntau txoj xov, koj xav tau synchronization rau cov khoom, uas tau koom nrog ntau cov xov, kom tsis txhob muaj kev noj nyiaj txiag ntawm lub xeev lossis txhua yam. tus cwj pwm tsis xav txog. Synchronization hauv Java tsuas yog xav tau yog tias cov khoom sib koom yog hloov tau.
Vim li cas peb thiaj xav tau synchronization hauv multithreading?
Lub hom phiaj tseem ceeb ntawm kev sib koom ua ke yog kom tsis txhob muaj xov cuam tshuam. Qee lub sij hawm thaum ntau tshaj ib txoj xov sim nkag mus rau cov peev txheej sib koom, peb yuav tsum xyuas kom meej tias cov peev txheej yuav raug siv los ntawm ib qho ntawm ib lub sijhawm. Cov txheej txheem uas qhov no ua tiav yog hu ua synchronization.
Vim li cas thiaj xav tau synchronization?
Synchronization yog ib qho tseem ceeb vim nws tshuaj xyuas qhov sib txawv ntawm ob lub thawv cov ntaub ntawv txhawm rau zam qhov tsis xav tau hloov pauv ntawm cov ntaub ntawv uas twb nyob hauv ob qhov chaw cov ntaub ntawv. Yog li ntawd, synchronization schemes feem ntau hloov kho ob qho tib si cov ntaub ntawv los ntawm kev hloov pauv tsuas yog ntxiv, hloov pauv, thiab tshem tawm.
Vim li cas peb thiaj xav tau synchronization hauv Java?
Synchronization hauv java yog lub peev xwm los tswj kev nkag mus ntawm ntau cov xov rau txhua qhov chaw sib koom. Hauv lub tswv yim Multithreading, ntau cov xov sim nkag mus rau cov kev sib koom ua ke ntawm ib lub sijhawm los tsim cov txiaj ntsig tsis sib xws. Lub synchronization yog tsim nyog rau kev sib txuas lus txhim khu kev qha ntawmxov xwm.
synchronization txhais li cas hauv multithreading?
synchronized txhais tau hais tias nyob rau hauv ib cheeb tsam ntau threaded, ib yam khoom uas muaj synchronized method(s)/block(s) tsis cia ob threads mus rau synchronized method(s)/block(s) code ntawm tib yam. sij hawm. Qhov no txhais tau hais tias ib xov nyeem tsis tau thaum lwm xov hloov kho nws.
