Ib array yog siv los khaws cov ntaub ntawv khaws tseg, tab sis feem ntau nws muaj txiaj ntsig zoo los xav txog ib qho array raws li ib tug sau los ntawm variables ntawm tib hom.
Koj muab ib qho array hauv Java li cas?
Tau txais ib array yog ob-kauj ruam txheej txheem. Ua ntej, koj yuav tsum tshaj tawm qhov sib txawv ntawm qhov xav tau array hom. Qhov thib ob, koj yuav tsum faib lub cim xeeb uas yuav tuav lub array , siv tshiab, thiab muab nws mus rau array sib txawv. Yog li ntawd, hauv Java tag nrho arrays yog dynamically faib.
